Abstract

The present invention is catalytic conversion method and apparatus and belongs to the field of petroleum hydrocarbon catalytically converting technology. The catalytic conversion method is that beside the heavy oil reactor of heavy oil reaction-regeneration apparatus, one gasoline reactor sharing the regenerator is connected in parallel, so that catalyst after passing through the gasoline reactor can enter to the heavy oil reactor for being mixed with the regenerated catalyst from the regenerator before reacting with heavy oil. There are one settler set in the outlet of the gasoline reactor and one catalyst conveying pipe set between the settler and the heavy oil reactor. The present invention can raise catalytic cracking yield, improve product quality and, especially, lower the content of olefin in gasoline.

Description

technical field

[0001] The invention belongs to the technical field of catalytic conversion of petroleum hydrocarbons, and in particular relates to a catalytic conversion method and device capable of increasing catalytic cracking yield, improving product quality, and especially reducing olefin content in gasoline. Background technique

[0002] Catalytic cracking is an important secondary processing method for petroleum heavy fractions. Especially in China, about 80% of gasoline comes from catalytic cracking units. How to improve the efficiency of catalytic cracking unit and improve product quality are very important. Conventional catalytic cracking methods and devices use riser reactors, which have obvious deficiencies in the reaction process. Firstly, the temperature of the regenerant is high, which limits the ratio of reactant to oil and the preheating temperature of heavy oil; secondly, the efficiency of the second half of the riser reactor is low; in addition, the prod...
