Abstract

The invention relates to a hydrogen cracking method of Fischer-Tropsch synthetic oil, which divides Fischer-Tropsch synthetic oil cut into light component and heavy component, wherein, the light is subjected to moderate hydrogenation processing; hydrogenation processing products and the heavy component are subjected to a second hydrogenation processing, products of which undergo separation and the separated tail oil is treated with hydrogen cracking, products of which and the products of the second hydrogenation processing enter a same separation system. Cetane value of diesel oil acquired from fractionation of liquid phase by employing the method of the invention is higher than 70, solidifying point is below 0 DEG C and content of sulfur and nitrogen is extremely low; therefore, the diesel oil acquired can produce 0 model high-quality clean diesel oil and can also serve as high-quality harmonic component to promote the cetane value of diesel oil; meanwhile, the naphtha acquired is high-quality raw material used for producing ethylene by steam cracking.

Description

technical field [0001] The invention relates to a hydrocracking method for Fischer-Tropsch synthetic oil, in particular to a hydrocracking method for processing Fischer-Tropsch synthetic oil into high-quality motor fuel and high-quality chemical raw materials. Background technique [0002] Fossil fuels mainly include coal and petroleum. From a global perspective, the reserves of coal far exceed the reserves of petroleum. Therefore, how to replace petroleum with coal is an important topic in the energy field. The important process for coal to replace petroleum is the liquefaction process of coal and the further processing process of coal liquefaction products. [0003] According to different routes of chemical processing, coal liquefaction can be divided into two categories: direct liquefaction and indirect liquefaction. Coal direct liquefaction is the direct conversion of coal into liquid products. The main processes include Exxon hydrogen-donating solvent method (EDS met...
