Description

technical field

[0001] The invention belongs to the technical field of auxiliary equipment for a hydrocarbon feedstock fluidized catalytic conversion device, in particular to a high-efficiency fluidized catalytic conversion stripper. Background technique

[0002] In the settler of the hydrocarbon feedstock fluidized catalytic conversion device, when the reaction is over, the catalyst after gas-solid separation still entrains some oil and gas, resulting in an increase in the amount of coke, energy consumption, and light oil yield. In this regard, steam stripping is often used to replace the oil and gas in the catalyst. The research results show that if all the oil and gas are replaced from the catalyst, the amount of coke can be reduced by about one-third, and the ratio of hydrogen to carbon in the coke can be reduced to 6%. Currently applied technology is still far from this goal.

[0003] The oil-gas displacement and desorption in the stripper is a typical gas-solid phase...
