Main technical principles and indicators: Coal is ground into fine powder, made into oil-coal slurry by circulating oil, and then directly hydrogenated and liquefied the coal through catalytic hydrogenation reaction at 440-470 ° C and 17-22MP high pressure conditions. Hydrogenation stabilization and hydrogenation upgrading are converted into liquid oil products.

Technical advantages: Completed the development of a complete set of core processes with independent intellectual property rights represented by "Direct Coal Liquefaction High-Efficiency Catalyst Preparation Process" and "Shenhua Direct Coal Liquefaction Process", and overcame the core process "Direct Coal Liquefaction High-Efficiency Catalyst" In the world-wide problem of amplifying 1000 times and "Shenhua Direct Coal Liquefaction Process" amplifying 30 times, the first set of million-ton/year demonstration projects has been successfully operated for 5 years and achieved long-term stable operation.

Application characteristics: The main products of direct coal liquefaction are diesel, naphtha and liquefied gas. The product has undergone multiple high-pressure hydrogenation processing and has the characteristics of high density, high volumetric calorific value, ultra-low freezing point, ultra-low sulfur and nitrogen content, and high naphthenic content. The exhaust gas after combustion contains very few pollutants, which can greatly reduce PM2.5 pollution and is a high-quality clean fuel; coal-to-liquids also have unique properties that petroleum products do not have, and can be used as high-quality special fuel in the aerospace field.

Economic and social benefits: A complete set of technologies with independent intellectual property rights and reaching the world's leading level has been formed, filling gaps at home and abroad; the sulfur content is less than 1mg/kg, which can be used as a high-quality blending component of gasoline and diesel; the development of special oils that are difficult to produce on petroleum routes, focusing on the development of military and aerospace special fuels, including special oils such as military ultra-low freezing point diesel, aviation jet fuel, and aerospace rocket kerosene.

Preliminary application demonstration situation:

Demonstration operation: In 2014, the direct coal liquefaction plant operated for 302 days a year and produced 902,000 tons of oil products.

Characteristic fuels: Carry out the development of coal-based special fuels by taking advantage of the advantages and characteristics of coal direct liquefaction oil products such as large proportion, high volumetric calorific value, high oxidation stability, low sulfur, and low freezing point. At the end of 2014, the test flight of fighter jets with a large proportion of jet fuel was completed, which can increase the endurance of my country's jet fighters by more than 8%; rocket engine tests have been successfully carried out in the development of liquid oxygen coal-based aerospace kerosene.

Status of R & D funding obtained: ■ "863"

Application situation or application prospects: In 2014, my country imported 310 million tons of oil, and my country has a large oil shortage; from the perspective of ensuring energy security, coal-to-liquids has important market space and strategic significance. With the development of my country's national defense, aviation and aerospace, characteristic fuels have broad application prospects.
