In May 2014, Guanghui Energy announced that it intended to form Gansu Honghui New Energy Technology Co., Ltd. and Gansu Honghui New Energy Sales Co., Ltd. in a joint venture with Jiuquan Iron and Steel (Group) Co., Ltd. According to the announcement, Gansu Honghui New Energy Technology Co., Ltd. has a registered capital of 3 billion yuan. The two shareholders shall make their contributions in installments as required by the project’s funding needs; each shareholder is liable for the company’s debts up to the amount of capital they have committed to contribute, while the company is liable for its debts with all of its assets. Both parties hold 50% of the shares each ； Gansu Honghui New Energy Sales Co., Ltd. has a registered capital of 10 million yuan, with each party holding 50% of the shares; either party in the joint venture may transfer part of its investment rights to its affiliated company. Gansu Honghui New Energy will be responsible for the construction of a project in Jiayuguan City, Gansu Province, aimed at the selective conversion and utilization of 30 million tons per year of raw coal. This project focuses on improving the quality of low-quality coal through coal pyrolysis; by installing coal gas purification units, hydrogen production units, and coal tar hydrogenation units, it enables efficient and selective utilization of coal resources. The main products of this project are high-quality coal, Hydrogenated Oil No. 1 (naphtha), and Hydrogenated Oil No. 2 (diesel), while the by-products include liquefied gas, dry gas, and hydrogenation tail oil. Guanghui Energy stated that the total investment required for the pilot project of hydrogenation and refining of 500,000 tons of coal tar as part of the first phase of the 10-million-ton coal utilization project is 2.568 billion yuan. This amount includes construction costs, interest on loans taken during the construction period, and working capital. Once operational, the pilot project will generate good economic benefits: the pre-tax internal rate of return is 25.62%. Over its 15-year operational life, it will achieve an average annual profit of 655 million yuan. In the year when it reaches full capacity, it will pay 211 million yuan in value-added tax, 27.4309 million yuan in various business taxes and fees, and an average annual income tax payment of 98.217 million yuan. The total return on investment is 25.67%, while the net profit margin on the project’s capital is 72.49%. The 500,000-ton coal tar hydrogenation refining project, which is part of the first phase of Gansu Honghui Energy’s 10-million-ton coal value-added utilization project, was designed by Changling Refining & Chemical Yueyang Engineering Design Co., Ltd. It makes use of the third-generation wide-distillation coal tar hydrogenation catalyst technology developed by Hunan Changling Petrochemical Technology Development Co., Ltd. Currently, the project has begun the bidding process for equipment. At the beginning of this century, Changling Petrochemical Technology Company developed the second-generation wide-range coal tar hydrogenation technology. The main features of this technology are as follows: The coal tar feedstock is pre-distilled into light and heavy oil fractions. The heavy oil fraction is subjected to the company’s proprietary extraction pretreatment process to remove salts, metals, and residues; the resulting extractable substances are then mixed with the light oil fraction. Subsequently, this mixture is processed through a fixed-bed reactor equipped with the company’s specially developed series of catalysts for wide-range coal tar hydrogenation, thereby enabling hydrogenation reforming to produce clean products such as hydrogenated naphtha, hydrogenated diesel, and hydrogenated tail oil. The 120,000-ton/year industrial plant built by Yunnan Pioneer Chemical using this technology was completed and handed over in June 2015. The third-generation wide-range coal tar hydrogenation technology is a new generation of technology developed by Changling Petrochemical Technology Company based on the second-generation wide-range coal tar hydrogenation technology, specifically for coal tar feedstocks with high dust and salt contents. This technology focuses on upgrading the pretreatment stage of second-generation processes; it utilizes a combination of the company’s patented FITS hydrogenation technology and patented membrane-enhanced desalination pretreatment technology. This approach further improves the removal efficiency of dust, water, salts, metals, and highly polar organic compounds from coal tar feedstocks. It also enables the saturation of most diolefins, styrene, and other precursors prone to coking, as well as the removal of impurities such as sulfur, nitrogen, and oxygen. As a result, the stability of the coal tar feedstock used in hydrogenation is improved, thereby ensuring the stability of catalyst activity in subsequent hydrogenation stages, as well as the smooth operation and continuous long-term functioning of the facility. In addition to Gansu Honghui Energy, Henan Longcheng Group has decided to use this technology to build a coal tar hydrogenation plant with an annual capacity of 2.4 million tons (800,000 tons per unit).

On July 6, 2015, it was reported from Xixia that after 7 years of research and development, the private enterprise Henan Longcheng Group has put into large-scale industrial use a technology for the classified and quality-based utilization of low-grade coal through low-temperature dry distillation (rotating bed pyrolysis technology). (Rotary kiln, CITIC Heavy Industry) In October 2011, a coal classification, quality separation, and clean, efficient utilization facility with an annual capacity of 300,000 tons operated by Longcheng Group in Xixia County, Henan Province, was put into formal operation. Through on-site calibration by experts organized by the China Petroleum and Chemical Industry Federation, the processing capacity of a single unit using this technology is 100 tons per hour; the yield of clean coal is 71.53%, the yield of coal tar is 11.05%, and the yield of gas is 9.87%. Coal tar and coal gas can be converted into gasoline, diesel, and liquefied natural gas through further processing. The technical design for an expansion project that utilizes the produced coal tar and gas to carry out hydrocracking for the annual production of 500,000 tons of diesel and gasoline is currently in progress. (Coke used as blast furnace injection coke) It is reported that the **Action Plan for Clean and Efficient Utilization of Coal (2015–2020)** issued by the Energy Bureau includes the hierarchical utilization of coal by classifying it based on its properties, with medium- and low-temperature dry distillation used to produce gas and oil as the main output methods, as part of the strategy for clean and efficient coal utilization. Longcheng low-temperature carbonization technology involves continuously heating coal under air-free conditions to a certain temperature, thereby transforming low-rank coals such as lignite and bituminous coal into clean coal, low-temperature coal tar, and gas. It is a typical technology for the graded and differentiated utilization of coal. In September 2014, this technology passed an evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation, with five academicians participating in the assessment. The conclusion was that: “This technology possesses entirely independent intellectual property rights and has reached an internationally leading level.” ” At present, the 10-million-ton-per-year project in Caofeidian, Hebei, with a total investment of over 4 billion yuan, has begun trial production, and the 12 units with a capacity of 870,000 tons per year are operating smoothly. Cao Guochao, the project leader, said that the two units currently in operation consume 4,800 tons of long-flame coal per day, producing 3,600 tons of clean blast furnace charging coal, over 480 tons of coal tar, and 380,000 cubic meters of gas, which are sold to steel and tar processing enterprises within a radius of several hundred kilometers. (Blast furnace coke injection) Low-temperature dry distillation not only turns coal into a whiter and clearer substance, but also enables the simultaneous production of coal gas, oil, and electricity, thereby generating greater economic and social benefits. Currently, the cost of refined oil in the petrochemical industry is 4,270 yuan per ton, while the cost of refined oil produced through direct coal liquefaction is 3,957 yuan per ton. In contrast, the cost using Longcheng’s low-temperature carbonization technology is only 1,724 yuan per ton ； The cost of producing LNG from natural gas is approximately 1.77 yuan per cubic meter, while the cost for producing gas from coal is around 2.1 yuan; Longcheng’s low-temperature carbonization technology reduces this cost to only 1.57 yuan per cubic meter. What is even more valuable are its significant energy-saving and emission-reduction benefits; during the dry distillation process, the desulfurization rate reaches 98%.
As a native of Gansu who works in the coal chemical industry, I am pleased to see the progress of my home province; it would be great if I could return there in the future to work in this field
Several other organizations, such as the Fuyan Research Institute, Shanghai Xinyou, Beijing Coal Research Institute, and Beijing Sanju Environmental Protection, are also working on developing hydroprocessing technologies for coal tar using fluidized bed and suspended bed systems. It’s unclear why Changling has such confidence in continuing to use the extraction pre-treatment + fixed-bed hydroprocessing technique
I have been in contact with Guanghui Coal Tar, and I want to get involved in the sales of coal tar; I’ll seek your advice more often in the future
The market for medium- and low-temperature coal tar is concerning this year; good luck to you~~
Which friend can share some experience in the low-temperature dry distillation of rotary kilns? Thank you
In the fixed-bed era, the reliability of coal tar pretreatment technology directly affects the long-term, stable, and efficient operation of the plant; the quality of this pretreatment is also crucial for improving yield. However, I personally believe that extraction pretreatment combined with fixed-bed hydrogenation always has bottlenecks that cannot be overcome; the yield reaches a certain level after which it can no longer be increased. Future development will mainly depend on the application of fluidized bed and suspended bed technologies. Once this technology becomes operational and stable over the long term, the technology for hydrogenating low-quality oil will change as a result. Here are my humble opinions for your reference.
After mastering suspended-bed and fluidized-bed technologies, it is convenient to expand business into kerosene co-processing as well as direct coal liquefaction.
He started driving at a very young age, thanks to his skills. . . Shaanxi Shuangyi and Chifeng Boyuan’s medium-temperature coal tar plants have been in operation for a long period of time
If it’s a fixed-bed system, didn’t Haga, Baotailong, and Inner Mongolia Qinghua start operating earlier? It took 4 years for Qinghua catalysts to be replaced with new ones. Fixed-bed technology is already very mature.
