The groundbreaking ceremony for Qitaihe Hongtaixing’s project to upgrade its coking facilities in order to produce clean chemicals (via coke gasification and Fischer-Tropsch synthesis) was held on September 4, 2015. The total investment in this project is 3.5 billion yuan, and it covers an area of 66 hectares; completion and operation are scheduled for December 2016. Once the project is in full operation, it will produce 200,000 tons of Fischer-Tropsch synthesized oil, 180,000 tons of synthetic ammonia, and 300,000 tons of urea per year. Additionally, it will generate 32,000 tons of LNG and 5,000 tons of LPG per year, as well as 600 million kWh of electricity. It is expected to generate sales revenue of 2,115.98 million yuan, profits of 444.71 million yuan, and taxes of 310.65 million yuan, while providing employment for 1,200 people. Using the abundant local chemical coke as raw material, this project produces syngas through pure oxygen-steam continuous gasification. Its main products are light liquid paraffin and heavy liquid paraffin, with LPG, LNG, and sulfuric acid by-products as secondary outputs. The production capacity of this unit is such that the gasification unit can produce 157,623 Nm3 of useful gas (CO+H2) per hour. Longpeng Coal Development Co., Ltd. has partnered with Beijing Sanju Environmental Protection Company to establish Hongtaixing New Energy Co., Ltd., with the aim of building a project for the upgrading of coking processes to produce 400,000 tons per year of clean chemicals; the total investment is expected to be 3.2 billion yuan. The project is divided into two sub-projects; one of them is the 200,000 tons per year FTO synthesis project, which is currently in the planning stage, with trial operation expected to begin in June 2016 ； The second is the 300,000 tons per year coal tar slurry bed hydrogenation project, which is expected to start construction in September 2015 and begin trial operation in December 2016. Based on information available online, the design of this project should be carried out by China Fifth Ring Engineering Design Company. Under the backdrop of low oil prices, Beijing Sanju Environmental Protection has leveraged its traditional coal chemical infrastructure for transformation, in order to reduce the costs associated with energy and hydrogen supply in the petrochemical industry. Essentially, this approach involves using coal as a substitute for oil. By partnering with coking companies, it is able to enter the high-margin field of coal-to-oil production; such collaborations result in investment costs that are 2/3 lower than those of new projects of similar scale, project timelines that are reduced by half, and gross margins that can reach 20%, which is 800% higher than the returns from traditional coking operations. According to Beijing Sanju Environmental Protection’s quarterly report for 2015, the technology used in this project is derived from the cobalt-based slurry-bed Fischer-Tropsch synthesis technology developed by the Dalian Institute of Chemical Physics under the Chinese Academy of Sciences. It is similar to the 150,000-ton/year cobalt-based slurry-bed Fischer-Tropsch synthesis demonstration project that was previously carried out by the Dalian Institute of Chemical Physics in collaboration with Yan’an Petroleum. In addition, Beijing Sanju Environmental Protection and the Dahu Research Institute are also advancing two other synthetic oil projects: the 200,000 tons per year clean chemicals (synthetic oil) project by Heilongjiang Huaben Bioenergy, and the 100,000 tons per year synthetic wax–environmentally friendly solvent oil project by Jiangyou Wanli Chemical. The construction period is about one and a half years.
Using the abundant local chemical coke as raw material, machine coke? Semicoke? Chemical coke? Metallurgical coke. ?
The Qitaihe Longpeng Coal Chemical Group is a private coal and coke chemical enterprise whose main business is the deep processing of coal. Founded in 2003, it has four subsidiaries. The group company has total assets of 1.86 billion yuan, covers an area of 88 hectares, and currently employs 1,860 people. Qitaihe Longpeng Coal Development Co., Ltd. is one of the four subsidiaries of the Longpeng Coal Chemical Group. It is a private joint-stock enterprise that integrates coal production, chemical manufacturing, and its own power generation facilities. Located in the Xinxing District of Qitaihe City, it was established in 2003. With total assets of 700 million yuan, a floor area of 240,000 square meters, and 550 employees, the company mainly produces products such as refined coal, coke, coal tar, and crude benzene. In recent years, the company has invested 40 million yuan to build a processing facility with an annual design capacity of 7,000 tons of crude benzene ； An investment of 30 million yuan has been made to build a self-generated power plant with an installed capacity of 2,500 kilowatts using the remaining gas, which can save 5 million yuan in costs each year ； An investment of 65 million yuan has been made to build a new coal washing plant with a capacity of 1.2 million tons. In 2009, the company invested 933 million yuan to build a new coke oven with a capacity of 980,000 tons and a methanol production facility with a capacity of 100,000 tons; completion and commissioning of these facilities were expected by December 2010. In 2009, the company achieved sales revenue of 1.46 billion yuan and paid taxes amounting to 95.46 million yuan. By 2012, the company was expected to achieve annual sales revenue of 2.8 billion yuan and profits and taxes of 500 million yuan. To align with the development model of a circular economy, optimize and upgrade the industrial structure of enterprises, establish a relatively complete coal coking industry scale, and achieve the goals of energy conservation, emission reduction, cost reduction, and efficiency improvement. In 2010, Longpeng Company established a new biomass briquette production project with an annual capacity of 300,000 tons. The total investment in this project was estimated at 173 million yuan; once it reached full operation, it could generate additional sales revenue of 500 million yuan and profits and taxes amounting to 60 million yuan.
Since it also has a 300,000 tons per year coal tar slurry bed hydrogenation project, it is likely that the coal tar obtained from coal carbonization is used for slurry bed hydrogenation, with the resulting coke being used to produce syngas.
Isn’t it from Baotailong? To provide an outlet for coking. Only when the returns are poor does one think of advanced processing; having funds and technology would help as well
“In the “coking upgrading project,” high-temperature coal tar can also be used in suspended-bed reactors

Coking transformation refers to the process in which coal coking plants previously produced coke and a small amount of coal tar through methods such as high-temperature dry distillation. The coke was mainly sold to steel mills for use in steel production; however, with the downturn in the steel industry, it has become difficult to sell coke. As a result, coke is now gasified to produce syngas, which is then used in Fischer-Tropsch synthesis to create synthetic oil (that is, indirect coal liquefaction). The small amount of coal tar obtained from coal dry distillation is processed through suspended-bed hydrogenation to produce diesel naphtha – this corresponds to the 300,000-tonne per year suspended-bed hydrogenation project for coal tar mentioned in the second phase.
Qitaihe is the city with the most developed coal chemical industry in Heilongjiang. The well-known Baotailong is just one company based in Qitaihe. It is known to everyone because Baotailong was the first to engage in the hydrogenation of high-temperature coal tar, but actually this project does not belong to them. In fact, this does not fall under the category of advanced processing of coal tar. The technology used for converting coke into syngas and then using that syngas to produce synthetic oil comes from the research team led by Ding Yunjie at the Institute of Chemical Technology, Chinese Academy of Sciences, while the suspension bed hydrogenation of coal tar was developed by Beijing Sanju Environmental Protection using catalysts provided by the Fushun Petrochemical Research Institute. Beijing Sanju Environmental Protection has a strong ability to integrate the technologies of various research institutes and companies, which has enabled the rapid industrialization of these technologies.
In simple terms, coal dry distillation produces coke and coal tar; coke is used to produce syngas, which is then converted into paraffin, diesel, and naphtha through the Fischer-Tropsch process, while coal tar is transformed into diesel and naphtha via hydroprocessing in a suspended-bed reactor.
As far as I know, the suspended-bed hydrogenation technology is not yet very mature in China. Although this technology originated in Germany during World War II, there is little understanding of it in the context of Fischer-Tropsch synthesis
