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
[0006] CN103773455A The invention discloses a method for combined hydrogenation of animal and vegetable oils and catalytic diesel oil. Essentially, catalytic diesel oil is processed through hydrogenation and refining. Although catalytic diesel oil can be processed through a suitable raw material ratio, due to the limitation of diesel product indicators , the amount of catalytic diesel that can be blended is very small, which cannot completely solve the problem of processing a large amount of catalytic diesel in large catalytic refineries
Although catalytic diesel components can be processed to produce high-octane gasoline through a certain catalyst gradation, the chemical hydrogen consumption is relatively high, which requires a large amount of hydrogen resources for enterprises

Abstract

The invention discloses a processing treatment 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 tohydrofining and hydroupgrading reactions and gasoline and diesel oil components are obtained; the obtained heavy component is separated, a triaromatic hydrocarbon component and a non-triaromatic hydrocarbon component are obtained, the obtained triaromatic hydrocarbon component is subjected to hydrofining and hydroconversion, and a gasoline component and a diesel oil 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 inferior catalytic cracking diesel oil can be reasonably used to produce qualified gasoline anddiesel oil products can be produced by reasonably utilizing inferior catalytic cracking diesel oil.

Description

technical field [0001] The invention relates to a method for processing 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 mor...
