Embodiment 1

[0024] The anthracene oil raw material is preheated and mixed with hydrogen into the first-stage hydrogenation reactor. The catalyst used is prepared with reference to the existing commercial hydrorefining catalyst, wherein molybdenum trioxide contains 17wt%, tungsten trioxide contains 11wt%, oxidation Nickel contains 3wt%, the rest is alumina carrier, the specific surface area is 160m 2 / g, the total pore volume is 0.7mL / g. The reaction conditions are: reaction temperature 380°C, reaction pressure 15MPa, hydrogen to oil volume ratio 1600:1, liquid hourly volume space velocity 0.3h -1 . The purpose of this refining stage is to carry out hydrodesulfurization, denitrogenation, and deoxygenation treatment on anthracene oil, and at the same time, part of the aromatics are saturated. After the resulting refined product is separated from gas and liquid by a high-pressure separator, the hydrogen-rich gas circulates and enters the reactor, and the obtained oil phase product enters t...

[0026] The first-stage refined product enters the second-stage hydrogenation reactor, and the catalyst used is prepared with reference to the existing commercial hydrocracking catalyst, wherein molybdenum trioxide contains 26wt%, nickel oxide contains 5wt%, silicon dioxide contains 30wt%, alumina Containing 39wt%, the specific surface area is 200m 2 / g, the total pore volume is 0.4mL / g. The reaction conditions are: reaction temperature 390°C, reaction pressure 15MPa, hydrogen to oil volume ratio 1600:1, liquid hourly volume space velocity 0.3h -1 . The purpose of this refining stage is to carry out deep aromatics saturation and ring-opening cracking treatment on the refined anthracene oil, so as to improve the low-temperature performance of the product and increase the calorific value. After the resulting refined product is separated from gas and liquid by a high-pressure separator, the hydrogen-rich gas circulates and enters the reactor, and the resulting oil-phase product ...

Embodiment 3

[0028] The second-stage refined product enters the third-stage hydrogenation reactor, and the catalyst used is a self-made noble metal / molecular sieve / alumina composite catalyst, in which platinum contains 0.5wt%, silica contains 8.8wt%, and alumina contains 90.7wt% , the specific surface area is 220m 2 / g, the total pore volume is 0.65mL / g. The reaction conditions are: reaction temperature 250°C, reaction pressure 4MPa, hydrogen to oil volume ratio 600:1, liquid hourly volume space velocity 0.6h -1 . The purpose of this refining stage is to further saturate the refined product with aromatics, so as to improve the stability of the product and further increase the calorific value. After the resulting refined product is separated from gas and liquid by a high-pressure separator, the hydrogen-rich gas circulates and enters the reactor, and the obtained oil phase product is tested as the final product.

Abstract

The invention discloses a method for producing high-energy hydrocarbon fuel through anthracene oil treatment. The method comprises the following steps: (1) carrying out first-stage non-noble metal catalytic hydrofining on anthracene oil, (2) carrying out two-stage non-noble metal catalytic selective hydrocracking on anthracene oil, and (3) carrying out third-stage selective hydrofining on the anthracene oil by a noble metal/molecular sieve composite catalyst. The method comprises the above three stage continuous hydrotreatment processes and efficiently converts anthracene oil into high-energyhydrocarbon fuel with high density (more than 0.88 g/mL), high calorific value (more than 40 MJ/L), low condensation point (less than -60 DEG C) and good stability. According to the method, full-fraction hydrotreatment is carried out by taking anthracene oil which is unique in China and takes polycyclic aromatic hydrocarbon as a characteristic as a raw material, so that the method has the advantages of high raw material utilization rate, environment-friendly process, reliable operation, stable product quality, long production and operation period and the like, and is very suitable for industrial promotion.

Description

technical field [0001] The invention relates to a method for processing anthracene oil to produce high-energy hydrocarbon fuel, and belongs to the technical field of coal chemical industry. Background technique [0002] As a general liquid fuel, hydrocarbon fuel is widely used in various aerospace vehicles such as airplanes, rockets, and missiles. In recent years, with the rapid development of my country's aerospace industry and military industry, the demand for various hydrocarbon fuels has increased significantly. Since the energy released by fuel combustion largely determines the important performance of the aircraft such as range, speed and load, the characteristics of the fuel itself are very important for different aircraft to fully perform their functions. Although the existing hydrocarbon fuel products can meet the needs of most aircraft, their volumetric calorific value is low. In order to achieve the ideal propulsion and range, the amount of use must be increased,...
