Hydrocarbon oil conversion method

Abstract

The present invention discloses a hydrocarbon oil convert method, wherein the method includes the following procedures: under cracking condition, contact hydrocarbon oil with energizing agent in a reactor to obtain reaction product and spent catalyst; separate the reaction product and spent catalyst, and contact the spent catalyst with water vapor and oxygen-containing gas inside a gasifying stove to obtain forming gas and semi-regenerated catalyst; separate the forming gas with the semi-regenerated catalyst, and transmit at least part of the semi-regenerated catalyst into the reactor for periodic duty, wherein reaction temperature inside the gasifying stove is from 500 DEG C to lower than 800 DEG C. The hydrocarbon oil convert method provided in the invention makes spent catalyst contactwith water vapor and oxygen-containing gas in the temperature from 500 DEG C to lower than 800 DEG C, and that can increase production quantity of carbon monooxide and hydrogen; carbon monooxide can be converted to hydrogen in the following course of working to obtain higher hydrogen rate of production; the energizing agent that regenerated in the temperature from 500 DEG C can improve hydrogen rate of production and improve product distribution of hydrocarbon oil reaction product.

Description

technical field

[0001] The invention relates to a hydrocarbon oil conversion method. Background technique

[0002] Catalytic cracking is one of the important means of petroleum secondary processing, which is used to produce gasoline, diesel, liquefied petroleum gas, etc. from heavy hydrocarbon oil. Generally speaking, the hydrocarbon oil cracking method includes contacting the hydrocarbon oil with a catalyst in a reactor under cracking conditions, and the hydrocarbon oil generates cracked products (the cracked products include light oil and gas) through a cracking reaction under the action of the catalyst. At the same time, the coke generated by the reaction is deposited on the catalyst, and the catalyst deposited with coke is generally called the spent catalyst; the spent catalyst and the cracked product are separated in the reaction settler, and the spent catalyst enters the reaction stripper to remove the carried oil gas After entering the regenerator for regeneration, t...
