Problems solved by technology

Although it is possible to process low-quality diesel from catalytic cracking, which increases the processing methods of inferior raw materials and converts them into high-quality products, the proportion of blended catalytic diesel is still limited to a certain extent, and the amount of catalytic diesel that can be processed is very small. Diesel hydrogen consumption is high

Abstract

The invention discloses a processing method of catalytic diesel oil. A catalytic diesel oil material is cut into a light component and a heavy component; the light component is subjected to hydrofining and hydroupgrading reactions and gasoline and diesel oil components are obtained; the obtained heavy component is subjected to hydrofining and hydroconversion, and a gasoline component and a dieseloil component are obtained; a gasoline product is obtained after the two parts of gasoline are mixed, and a diesel oil product is obtained after the two parts of diesel oil components are mixed. Through reasonable separation and processing processes, different types of raw materials can be selectively and independently processed, so that qualified gasoline and diesel oil products can be produced by reasonably utilizing inferior catalytic cracking diesel oil .

Description

technical field [0001] The invention relates to a processing method of catalytic diesel oil, in particular to a method for processing catalytic cracking diesel oil to produce high-quality gasoline and simultaneously producing high-quality diesel oil. Background technique [0002] Catalytic cracking is currently the most important secondary processing process in the petroleum refining industry, and it is also the core process of lightening heavy oil. As the world's oil becomes increasingly heavy, the processing capacity of the FCC unit is also continuously improved. Using various heavy oils as raw materials, high-octane gasoline, the main product, is obtained through catalytic cracking reactions, and a large amount of sulfur, nitrogen, and aromatics are produced at the same time. Catalytic diesel oil with high content, low cetane number or cetane index, and extremely poor stability. Moreover, the requirements of environmental protection regulations are becoming more and more...
