Problems solved by technology

[0005] (1) It is used to extract chemical products such as phenol, benzene, naphthalene, anthracene, etc., but the residues after extraction of chemicals still have pollution problems;
[0006] (2) Light fractions or whole fractions of coal tar are light fractions after delayed coking, fixed-bed hydrofining, and hydrocracking to produce ordinary gasoline and diesel products, and the added value of the products is low;
[0007] (3) After reconciliation, it is directly used as low-quality fuel and extensive fuel, causing serious environmental pollution and a great waste of precious coal tar resources
Due to the use of an acidic catalyst, this method has certain requirements on the nitrogen content of the feedstock oil, so it is not suitable for all coking gasoline and diesel raw materials, and it is also difficult to deal with inferior naphthenic coking distillates

Embodiment 1

[0067] Using a low-temperature coal tar as raw material, the purified coal tar after dehydration and deslagging (solid impurities) pretreatment enters the distillation unit and is cut into high phenolic distillate oil less than 230°C, distillate oil from 230°C to 350°C and distillate oil greater than 350°C ℃ distillate oil. The distillate oil with high phenol content below 230°C is mixed with the distillate oil at 230°C to 350°C after the crude phenol product is extracted by the phenol extraction unit. The light distillate oil after mixing is the raw material oil for preparing military fuel in the present invention, and its properties are shown in Table 1. Mixed light distillate oil can be processed into 3# jet fuel, common battlefield fuel, rocket kerosene and high specific gravity jet fuel after deep hydrofining and proper blending. The main process conditions of each process unit are shown in Table 2. Each military fuel product The main properties are shown in Table 3. The...

Embodiment 2

[0069] Using a medium-temperature coal tar as raw material, the purified coal tar after dehydration and slagging (solid impurities) pretreatment enters the distillation unit, and is cut into high-phenol fraction oil less than 230°C, distillate oil from 230°C to 450°C, and distillate oil greater than 450°C ℃ distillate oil. The distillate oil with high phenol content below 230°C is mixed with the distillate oil at 230°C-450°C after the crude phenol product is extracted by the phenol extraction unit. The light distillate oil after mixing is the raw material oil for preparing military fuel in the present invention, and its properties are shown in Table 1. Mixed light distillate oil can be processed into 3# jet fuel, common battlefield fuel, rocket kerosene and high specific gravity jet fuel through deep hydrorefining, tail oil hydrocracking, product fractionation and proper processing and blending. Each process unit mainly The process conditions are shown in Table 2, and the main...

Embodiment 3

[0072] Using a high-temperature coal tar as raw material, the purified coal tar after dehydration and slagging (solid impurities) pretreatment enters the distillation unit, and is cut into high-phenolic distillate oil less than 230°C, 230°C-365°C distillate oil and >365°C ℃ distillate oil. The distillate oil with high phenol content below 230°C is mixed with the distillate oil at 230°C-365°C after the crude phenol product is extracted by the phenol extraction unit. The light distillate oil after mixing is the raw material oil for preparing military fuel in the present invention, and its properties are shown in Table 1. Mixed light distillate oil can be processed into 3# jet fuel, common battlefield fuel, rocket kerosene and high specific gravity jet fuel through deep hydrorefining and proper processing and blending.

Abstract

The invention discloses a coal-based military fuel and a preparation method thereof. The method comprises the steps of: (1) carrying out distillation cutting on raw oil so as to at least obtain a light fraction and a heavy oil fraction, wherein the raw oil is one or more of oil produced through direct coal liquefaction, oil produced through refining coal and oil together, and pretreated coal tar; (2) enabling the light fraction to enter a hydrofining reactor for hydrofining; and (3) enabling oil produced through hydrofining to enter a fractionating tower for fractionating after the oil is subjected to cooling and gas-liquid separation, thereby obtaining the military fuel. According to the method, the scope of application is wide, the process flow is reasonable, the raw material utilization ratio is high, the varieties of products are multiple, and the operation is flexible, so that the method can be applied to the mass production of various special oils.

Description

technical field [0001] The invention belongs to the field of coal chemical industry, and relates to a method for deep processing and utilization of coal-based oil products, in particular to a method for producing various military fuels by using coal tar, and is also suitable for the production of oil produced by direct liquefaction of coal and co-refining of kerosene Various methods of military fuel. Background technique [0002] Today, the world situation is unstable, and the possibility of local wars and emergencies is increasing. In future wars, military fuel supply has become one of the key links in determining the outcome of a war. In military fuel consumption, the consumption of fuel is far greater than that of other fuels. At present, my country's military fuels are all petroleum-based fuels, and my country's resources are characterized by rich coal, poor oil, and lack of gas. The dependence on foreign oil has exceeded 50%, and international oil prices continue to ri...
