Analysis of the Current Status and Prospects of the Industrialization of Coal-to-Oil Technology in China – An analysis report provided by Xinhua News Agency. For a long time, the energy exploration landscape in China, characterized by abundant coal, limited oil reserves, and available natural gas, has led to a general shortage of liquid fuels in the country. With tight crude oil supplies and rising prices, many regions in the country have been facing oil shortages recently, putting energy security to the test. Meanwhile, calls in the country for the development of the coal-to-oil industry are growing louder, accompanied by ongoing controversies. Experts believe that, given the nearly 80-year history of coal-to-oil technology, there are risks associated with China’s development of this industry, yet its strategic significance is immense. ——An overview of the development of coal-to-oil technologies at home and abroad. According to Tang Hongqing, deputy chief engineer and professor-level senior engineer at Sinopec Ningbo Engineering Co., Ltd., which provided technical support for Inner Mongolia Yitai Group’s coal-based indirect oil production demonstration project, coal-to-oil conversion can be achieved through two processes: synthetic oil production (indirect liquefaction) and direct liquefaction. Synthetic oil production refers to the technology of converting coal into oil through processes such as gasification, desulfurization, purification, and catalysis. As early as the 1920s, German scientists discovered that liquid fuels could be produced by using iron catalysts to synthesize gas. In 1934, the German company Ruhrchemie began building the first coal-fueled synthetic oil plant, designed to produce 40 million liters per year. By the end of World War II, Germany had built 9 synthetic oil plants, with a total production of 570,000 tons. During the same period, countries such as France and Japan also built 5 synthetic oil plants, with an annual total production capacity of 340,000 tons. During and after World War II, these factories were either destroyed or closed due to their inability to compete with oil companies. South Africa, which is rich in coal, was subject to **international economic sanctions for much of the mid-20th century; lacking oil supplies, it was forced to develop coal-to-oil technology. In 1955, SASOL’s first coal-to-oil plant came online; two more plants of the same type were built in 1980 and 1982 respectively, with continuous improvements being made to coal-based indirect oil production technology. Currently, SASOL produces over 7.6 million tons of oil products and chemicals per year, making it the largest coal-to-oil company in the world. The direct coal liquefaction process is a technology in which coal is ground into powder and mixed with liquefying heavy oil to form a coal slurry; under high temperature, high pressure, and catalytic conditions, the organic compounds in the coal are directly converted into liquid fuels and other chemical products through hydrocracking. In 1913, German scientists conducted research and obtained the world’s first patent for coal direct liquefaction technology. In 1927, Germany built the world’s first plant for direct coal liquefaction, which the chemical industry referred to as the first generation of direct coal liquefaction technology. Subsequently, between 1936 and 1943, Germany put into operation another 11 sets of coal direct liquefaction plants; by 1944, the country’s direct liquefaction capacity had reached 4.23 million tons, meeting two-thirds of Germany’s aviation fuel needs and 50% of its vehicle fuel requirements at that time. Some of these plants were destroyed during **, while the rest were shut down due to high costs. The second generation of coal direct liquefaction technologies emerged after the 1973 oil crisis, when energy-consuming countries began to pay renewed attention to this technology. Various new processes were developed, all of which completed pilot tests; however, high costs and substantial investment requirements prevented their industrialization. Currently, the third-generation coal direct liquefaction technology is under development internationally. What is little known is that our country was **one of the earliest in the world to have coal-to-oil plants**. According to Tang Hongqing, in 1937, Japan introduced German coal-to-oil technology at the Jinzhou No. 6 Oil Plant; the project came online in 1943, and production ceased after Japan’s defeat in 1945. After the founding of the People’s Republic of China, China restored and expanded the Jinzhou coal-to-oil facility; at its peak in 1959, it had 70 box-type reactors and produced 47,000 tons of oil products per year. Operations were halted in 1967 due to the discovery of the Daqing oil field. ——China’s technical barriers in coal-to-oil production have been overcome. According to data released by the General Administration of Customs, in the first half of 2007, China’s imports of crude oil and refined oil amounted to 81.54 million tons and 18.05 million tons respectively, resulting in an import dependence rate of 47%. Since the second half of the year, import volumes have continued to reach new highs, with crude oil prices once reaching nearly 100 dollars per barrel. Recently, the ex-factory prices of gasoline and diesel in our country have been increased by 500 yuan per ton. Although CNPC and Sinopec have been tasked with maintaining stable market supply, some cities still faced shortages of fuel in the short term; therefore, it has become urgent to explore alternative sources for liquid energy supply. Since the founding of the People’s Republic of China, the former Dalian Petroleum Research Institute and the Shanxi Coal Research Institute of the Chinese Academy of Sciences have carried out research on kiloton-scale pilot plants for synthetic oil, making continuous breakthroughs. In the 1950s, the Chinese Academy of Sciences also carried out research on direct coal liquefaction for oil production, and built a pilot plant with an annual output of 5,000 tons; however, operations were halted due to the shutdown of the Daqing oil field. Since the 1970s, our country has resumed research on direct coal liquefaction technology; in recent years, breakthroughs have been achieved in this field, and a team of researchers has been developed. In August 2002, Shenhua Group’s project for direct coal-to-oil conversion was approved by the State Council and designated as a **major energy strategic project, marking a new milestone in China’s coal-to-oil technology. In recent years, coal-to-oil technology in our country has advanced rapidly. Li Yongwang, a researcher at the Shanxi Institute of Coal Chemistry under the Chinese Academy of Sciences, deputy director of the Key Laboratory of Coal Conversion, and the lead scientist on the \"coal to oil\" project, revealed that in recent years, organizations such as the China National Coal Research Institute, Shenhua Group, the Shanxi Institute of Coal Chemistry of the Chinese Academy of Sciences, and Yankuang Group have been involved in this area of research.

Research institutions have successively developed technologies for the direct and indirect liquefaction of coal to produce oil; pilot tests have been successful, and breakthroughs have also been achieved in the development of related hardware, control software, and catalysts. The pilot-scale test results from the 1,000-ton facility at the Shanxi Coal Chemistry Institute of the Chinese Academy of Sciences show that the cost of producing oil using the indirect liquefaction process is on par with or even lower than the international level. According to Li Yongwang, since breakthroughs were achieved in this technology, the world’s largest coal-to-oil company, South Africa’s SASOL, no longer designates any restricted areas in various technical processes when receiving Chinese officials for inspections, and it sends people to China frequently for exchanges. Based on theoretical, technical, and pilot-scale test results, China has fully mastered the core technologies for coal-to-oil conversion, and the time is ripe for industrialization. ——Analysis of the development scale of China’s coal-to-oil industry in the short to medium term. With tight crude oil supplies, there is growing enthusiasm and demand for the construction of coal-to-oil projects in China. Since 2004, the coal-to-oil demonstration projects of Shenhua Group and Yitai Group in Ordos City, Inner Mongolia, have progressed smoothly and are now in the final stage of completion. The total planned capacity for these two projects is 5 million tons and 480,000 tons respectively. By the end of 2007, Shenhua Group’s first oil production line with a capacity of 1.08 million tons for direct oil production, and Yitai Group’s first oil production line with a capacity of 160,000 tons for indirect oil production, will be largely completed, with trial production to begin in 2008. Meanwhile, the other 5 demonstration projects developed by enterprises such as Yankuang Group and Lu’an Mining Group are also being accelerated, with plans for them to enter the trial production phase over the next two years. At present, the Shanxi Institute of Coal Chemistry under the Chinese Academy of Sciences is providing technical support for demonstration projects such as those carried out by Shenhua Group, Yitai Group, and Lu’an Mining Group. Following the success of the initial pilot projects, it will promote the industrialization of China’s independent coal-to-oil technology at a scale of over one million tons per year. Furthermore, once the 1 million-ton coal indirect liquefaction oil production project of Yankuang Group is completed successfully, it will be the first coal indirect liquefaction oil production project to operate at a scale of one million tons. The follow-up plans for the demonstration projects of Yitai Group and Lu’an Mining Group are also being formulated, with an planned annual production capacity of over 3 million tons, above the economic threshold. However, the emerging coal-to-oil industry also currently faces the risk of reckless planning. According to interviews with journalists, in addition to the first batch of 7 **pilot projects, provinces and autonomous regions such as Inner Mongolia, Shaanxi, Henan, Anhui, Ningxia, Guizhou, Xinjiang, Heilongjiang, and Shanxi are also preparing or planning other coal-to-oil projects. Some areas have planned more than one such project, with capacities ranging from several hundred thousand tons to over a million tons. Experts predict that, given the current trend of development, by around 2020, the scale of China’s coal-to-oil industry will reach 30 million to 50 million tons. ——Analysis of the Risks and Opportunities Facing the Coal-to-Oil Industry The shortage of liquid fuels poses a serious threat to China’s energy security. Currently, there is both the technology and the need to develop the coal-to-oil industry; it can provide a new way to ensure **energy supply and significantly reduce China’s reliance on imported oil. However, the technology required for coal-to-oil projects involves an investment of around 100 million yuan per 10,000 tons of production capacity – an amount that is quite high. Additionally, China lacks experience in industrializing such technologies on its own, and there are also technical risks involved. For example, if a 160,000-ton coal-to-oil production line fails, the losses could range from 500 million to 700 million yuan. The investment for a million-ton oil production facility exceeds 10 billion yuan, meaning that any failure would result in enormous losses. Furthermore, it is argued that the market risks associated with coal-to-oil production are also relatively high. Although China has large total coal resources, when distributed among its 1.3 billion people, the per capita amount of these resources is relatively low on a global scale. Indirect and direct oil production technologies require approximately 3.5 tons and 4.2 tons of coal respectively to produce one ton of oil, with resource utilization rates of less than 30% and 50% in each case. Not only is there high coal consumption, but the low utilization rates also lead to serious waste. Producing one ton of oil products requires more than 10 tons of water, and pollution from waste gases and other substances is also much higher than that of ordinary refining projects. Since developed countries such as the United States have not developed the coal-to-oil industry on a large scale, some even argue that coal-to-oil is a \"technical trap\". It is normal for any new thing to be questioned or even opposed; understanding takes time. According to Li Yongwang, from the perspective of the overall energy strategy, coal-to-oil production holds extraordinary strategic significance and long-term benefits; moreover, pollution issues can be overcome through the adoption of technological innovations and cleaner production methods. Regarding technical risks, industrial production of oil from coal was already carried out on a large scale internationally in the 1920s and 1930s. Today, China’s chemical technologies and industrial equipment are **more advanced than they were back then, resulting in lower technical risks and a significantly shortened industrialization timeline. Regarding market risks, based on current coal prices at the mine site, the cost per barrel of oil produced through direct and indirect coal liquefaction demonstration projects is around $35 to $38. Li Yongwang analyzed that if the optimal economic scale of 3 million tons is reached, and assuming a coal price at the mine site of 150 to 200 yuan, the cost per barrel of oil products would drop to around 30 dollars. Especially once the fifth-generation catalysts under development are successfully implemented, the catalytic efficiency is expected to increase by about 30%, further reducing costs. ——Experts offer suggestions for the development of the coal-to-oil industry. Relevant experts point out that although there is already the necessary technology and market demand for developing this industry in China, it should still be advanced in a scientific and steady manner to avoid a rush to enter this field. First, although the coal-to-oil industry has a history of nearly 80 years, it remains a completely new industry for China. At present, there is a severe shortage in China of experience and talent in areas such as technology and operation; therefore, research institutions must provide support, and it is recommended to offer assistance in research and talent development. Second, strictly enforce the regulations on restricting approvals; first establish demonstration projects, and the scale of such projects should also start small before increasing. It is reported that industrial facilities with a capacity of over 100,000 tons require low initial investment, and the cost for a single trial run ranges from 20 million to 30 million yuan; companies have the capacity to absorb such costs. Investing in a plant with a capacity of millions of tons requires billions of yuan; the cost of a single trial run can amount to two or three hundred million yuan, and any failure would result in huge losses. For example, if the first production line fails, Yitai Group would suffer overall losses of around 600 million to 700 million yuan, which is a substantial amount; such a loss could severely weaken an ordinary company. Third, calculations show that the current volume of 3 million tons represents the economic scale for coal indirect liquefaction oil production projects. At present, the planned scale for the follow-up projects of these demonstration projects is all above one million tons; among them, Yitai Group plans 5 million tons, Lu’an Mining Group plans 5.2 million tons, while the projects planned by companies such as Xuzhou Mining Group are all 3 million tons. With the advancement of technology and the accumulation of production experience, as coal-to-oil production shifts from industrial demonstration to large-scale industrialization, small enterprises are unable to survive. Fourth, coal-to-oil projects consume large amounts of coal, and low coal prices are the foundation for their development. The first batch of demonstration projects are all located near large coal enterprises, in the heart of major coal fields. Therefore, when planning industrial development in the future, it is still necessary to adhere to the pithead principle and pursue co-production of coal and oil; coal should be sufficient to meet the needs of oil production projects for 30 to 50 years, in order to minimize costs and enhance resilience to market risks. It is particularly important to note that similar projects should not be established in areas lacking coal resources.
