Separation method for solid particles in catalytic slurry oil

Abstract

The invention relates to a separation method for solid particles in catalytic slurry oil and belongs to the technical field of petrochemical complex. Special assistant is added into the high-solid-content catalytic slurry oil and is stirred and mixed reasonably; and then solid-liquid separation equipment is adopted to conduct separation effectively, so as to obtain lower-ash-content and good-quality catalytic slurry oil. The invention has the advantages that the process and the equipment are simple, the operation is easy, the production is continuous, and the solid-liquid separation is complete, so as to obtain the lower-ash-content and good-quality catalytic slurry oil and broaden the application range of the lower-ash-content and good-quality catalytic slurry oil.

Description

technical field

[0001] The invention relates to the technical field of petrochemical industry, in particular to a method for separating solid particles of catalytic oil slurry. Background technique

[0002] Catalytic oil slurry is the remaining part of crude oil after catalytic cracking and catalytic cracking, accounting for about 10% of processed crude oil, which contains a large number of solid particles. In the prior art, the catalytic oil slurry is only used as a fuel oil blending component or a raw material for producing petroleum coke, and the added value is not high. However, the catalytic oil slurry containing a large amount of condensed aromatic hydrocarbons is an excellent raw material for the production of carbon products such as carbon fiber, carbon black oil, and needle coke. But the solid particles in the catalytic oil slurry affect its use. The solid particles in the catalytic oil slurry mainly come from the entrainment of catalyst powder in the reactor. Th...
