As of the end of last week, China's first high-temperature coal tar hydrogenation unit has been running smoothly for 398 days, indicating that the high-temperature coal tar hydrogenation technology independently developed by China has matured. This is China's succession of energy ladders following the application of low-temperature coal tar and medium-temperature coal tar hydrogenation technology, which has opened up a new way for coal tar processing. Song Xixiang, president of Baotailong Coal Chemical Co., Ltd. in Qitaihe, Heilongjiang Province, introduced that the 100,000-ton high-temperature coal tar hydrogenation unit was completed by the company in cooperation with Shanghai Shengbang Petrochemical Technology Co., Ltd. The project makes use of the market advantage of shortage of fuel oil in our country, the advantages of coal tar resources in Qitaihe and surrounding areas, and uses coal tar hydrogenation technology to produce clean oil products that are in short supply in the market. Compared with medium- or low-temperature coal tar hydrogenation technology adopted by enterprises in Shanxi, Shaanxi, etc., the high-temperature coal tar hydrogenation of the raw material fraction is more heavy, the asphaltene content is high, and the coal tar density in the raw material is higher by 0.1%~ 0.15%. It borrowed from the petrochemical industry heavy oil and high pressure hydrocracking process, higher than the hydrogenation pressure of low temperature coal tar 5.0MPa, to achieve the high temperature coal tar polycyclic aromatic hydrocarbons hydrocracking. The special catalysts used in this technology are more selective, refining and cracking effects are more thorough. In the northern cold regions, especially in the high latitudes and cold regions such as Heilongjiang and Inner Mongolia, high-temperature coal tar hydrogenation products can solve the problem of winter diesel's dew condensation, and it has already begun to be applied. It is understood that the 300,000 tons/year high-temperature coal tar deep-processing project, which is supported by a 100,000-ton/year high-temperature coal tar hydrogenation unit, was started in Baotailong Company in May of this year, including 300,000 tons of coal tar pretreatment. Project and 50,000 tons/year needle coke project. Among them, the 50,000-tonne/year needle coke project is the third similar project in China and will innovate the circular economy development model of China's coal chemical industry, realizing the leap from traditional coal chemical industry to modern coal chemical industry. It is also known that the high-temperature coal tar hydrogenation technology uses a fixed bed hydroprocessing technology to remove the sulfur and nitrogen contained in the coal tar, and to saturate the olefins and aromatic compounds therein, thereby producing clean oil products. . Its technological innovation is reflected in three aspects: First, targeted selection of coal tar hydrorefining and cracking catalysts, suitable reactivity, rapid hydrogenation in the cracking process, reducing the catalyst coking probability in the hydrocracking process, The catalyst life is extended; the second is to control the vacuum tower under proper vacuum conditions to avoid the use of steam jet pumps to discharge a large amount of oily sewage and reduce the energy consumption of the device; third is to use proprietary technology to carry out the energy at each temperature level. Fully optimize the design and achieve energy ladder utilization.
