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...
