Abstract

The invention discloses a hydro-conversion method, in particular to a long distillate raw oil hydro-cracking method. The method comprises: mixing a long distillate raw oil with the generated stream in a second hydrogenation reaction zone to enter a first hydrogenation reaction zone, separating the generated stream after the hydro-treating reaction to obtain hydrogen-rich gas and liquid, recycling the hydrogen-rich gas, putting the liquid into a fractionating tower for fractionation to obtain light-end products and tail oil, mixing the tail oil with hydrogen to enter the second hydrogenation reaction zone, and putting the generated stream in the second hydrogenation reaction zone into the first hydrogenation reaction zone. Compared with the prior art, the method realizes the direct production of clean automotive fuel and high quality chemical raw materials by long distillate raw materials in a set of hydrogenation systems, thereby reducing the equipment investment and operating cost.

Description

technical field [0001] The invention relates to the field of petroleum or alternative liquid fuel processing, in particular to a method for producing light clean fuel and chemical raw materials by hydrocracking wide-distillation raw material oil. Background technique [0002] Petroleum and its products have accelerated the process of modernization and continue to play an important role. According to a 2007 report by the American Journal of Oil and Gas, almost all crude oil in the world has tended to become heavier in the past five years. At present, the world's total oil consumption continues to increase, while environmental protection regulations are becoming increasingly stringent, requiring further reduction of sulfur content in high-quality motor fuels, and even some countries have reached the stringent standards for the production of sulfur-free fuels, while other product specifications are also restricted, such as gasoline, diesel Aromatics content, diesel cetane numb...
