Abstract

The present invention provides catalytic reaction method and reactor capable of improving reaction condition and raising the product yield. The present invention features that catalyst is made to reflux in the reactor and this can lower the temperature of catalyst contacting with reacted material, increase the practical catalyst amount, inhibit thermal cracking reaction, raise product yield, raise the catalyst inventory and catalyst / oil ratio in the second reaction region, improve product distribution and raise product quality. The reactor of the present invention features its catalyst reflux without affecting the operation of the other parts and without needing improving or increasing depositor. The present invention can raise product yield and lower the olefin content in gasoline product.

Description

technical field

[0001] The invention belongs to the technical field of petroleum catalytic conversion devices, and in particular relates to a method and a riser reactor which can be used for catalytic conversion of petroleum hydrocarbon raw materials. Background technique

[0002] Almost all existing catalytic conversion devices for petroleum hydrocarbon raw materials (including atmospheric heavy oil, vacuum oil press, vacuum wax oil, coker wax oil, gasoline, etc.) use riser reactors, and the reaction raw materials are catalytically converted in the riser reactor to form Gasoline, diesel, liquefied petroleum gas and other reaction products.

[0003] With the deepening and popularization of research work, the catalytic conversion reaction process and equipment have been continuously improved. Advances in reaction engineering can be divided into two aspects: the associated conditions and the reaction process itself. In the field of related conditions, a variety of more effic...
