Abstract

The invention relates to a process for producing light aromatics and clean fuel oil by hydrocracking catalytic cracking diesel oil through moving bed. The process comprises the following steps: 1) mixing catalytic cracking diesel oil and hydrogen into a fixed bed hydrotreating reactor Hydrofining reaction to remove sulfur and nitrogen impurities, and carry out hydrogenation saturation of olefins and hydrogenation saturation of partial aromatic rings of condensed aromatic hydrocarbons; After mixing, enter the moving bed hydrocracking reactor for deep hydrocracking reaction, and realize the separation of hydrocracking products and deactivated catalyst at the outlet of the reactor; 3) The deactivated catalyst recovers the hydrocracking activity through online charring and sulfidation 4) Hydrocracking products are separated and fractionated to obtain liquefied gas, light aromatics, high-octane clean gasoline blending components and clean diesel blending components.

Description

technical field

[0001] The invention relates to the technical field of petrochemical industry, more specifically, the invention relates to a process or method for producing light aromatics and clean fuel oil by hydrocracking in a moving bed. Background technique

[0002] The environmental pollution caused by vehicle exhaust emissions has become a major problem that must be solved for the sustainable development of the national economy and society. For this reason, the standards for vehicle fuels in various countries in the world are becoming increasingly strict. The country has implemented the National IV clean fuel standard on January 1, 2015, and will implement the National V diesel quality index on January 1, 2017. The National VI diesel quality index is also being formulated, which will affect the development of my country's oil refining industry. posed great challenges. The annual processing capacity of catalytic cracking units in my country has exceeded 100 million ton...
