Problems solved by technology
This method mainly describes that coal tar is fractionated first, and the heavy fraction obtained is not used as the raw material for hydroprocessing, but only the light fraction in coal tar is hydrotreated. Since no hydrocracking catalyst is used, the diesel fraction is obtained during the processing It can only be used as a blending component of diesel products, and coal tar has not been fully utilized, resulting in a significant reduction in the overall yield of light oil products

The invention discloses the coal oil hydrocracking method. The method comprises the following steps: mixing the coal oil and hydrogen gas, adding them into hydrogenation reaction chamber, getting the generating oil, putting the generating oil into heat-high pressure separator, getting light-end products and water from upper logistics, putting lower logistics and hydrogen gas into hydrocracker reaction chamber, getting hydrocracking product, putting the product into high pressure separator, getting hydrogen gas to be used again, and putting the liquid into fractionating tower to get gas, petrol, diesel, light-end products and tail oil. The invention uses low grade coal oil to produce premium grade gasoline and diesel.
Description
technical field [0001] The invention relates to the field of high-quality motor fuel production, and in particular relates to a coal tar hydrocracking method, that is, coal tar is used as raw material oil, and light oil is produced through methods such as hydrogenation pretreatment and hydrocracking widely used in the field of petroleum processing. Motor fuel oil products, so that not only clean use of coal tar, but also broaden the source of motor fuel oil. Background technique [0002] The world's demand for motor fuel is increasing, and the quality requirements for motor fuel are getting higher and higher. Due to political reasons and restrictions on the amount and total amount of oil resources extracted, the price of crude oil continues to remain high, coupled with increasingly stringent environmental protection regulations, it is necessary to produce motor fuels that meet environmental protection requirements, resulting in an increase in the production cost of the refin...
