Embodiment

[0052] The coal tar is subjected to hydrogenation and light treatment. The specific treatment conditions are: temperature 220°C, pressure 11.0MPa, weight hourly space velocity 2.4h -1 , the ratio of hydrogen to oil is 1300:1; the fractional distillation of the hydrogenation product obtains light coal tar, the initial boiling point of which is 40°C, the final boiling point is 175°C, 0.73g / mL, and the carbon-hydrogen ratio is 0.35 :1.

[0053] use as figure 1 The shown vehicle fuel preparation process carries out the isomerization reformation of light coal tar:

[0054] The above-mentioned light coal tar is cut into four fractions through splitter 1 (atmospheric fractionation tower): the first light fraction 25%, the first middle fraction 38%, the first heavy fraction 27% and kerosene product fraction 10%; The cut point of the first light distillate is 85°C; the cut point of the first middle distillate is 122°C; the cut point of the first heavy distillate is 163°C; the kerosen...

Abstract

The invention relates to a method for preparing vehicle fuel from light coal tar. According to the method, the light coal tar is subjected to fractionation, different isomerization treatment processesare adopted for different fractionation products, the vehicle fuel with the high octane number is obtained, and coal tar resources are fully utilized. The method has the advantages of being high in product purity, high in yield, simple in process and wide in application range.

Description

technical field [0001] The disclosure relates to the field of coal chemical industry, in particular to a method for preparing vehicle fuel from light coal tar. Background technique [0002] Vehicle fuel mainly includes vehicle gasoline, vehicle diesel, and vehicle alternative fuels (such as methanol, ethanol, emulsified fuel, natural gas, petroleum gas, hydrogen), etc. The use performance of vehicle fuel has a direct impact on the power and emission of vehicles. The consumption of vehicle fuel accounts for about 1 / 3 of the cost of vehicle transportation, which directly affects the economy of vehicle use. [0003] Vehicle fuel mainly includes vehicle gasoline, vehicle diesel, vehicle alternative fuels (such as methanol, ethanol, emulsified fuel, natural gas, petroleum gas, hydrogen), etc. The use performance of vehicle fuel has a direct impact on the power and emission of vehicles. The consumption of vehicle fuel accounts for about 1 / 3 of the cost of vehicle transportation...
