Spent catalyst sorting apparatus for Residue Fluid Catalytic Cracking

摘要

The present invention relates to a waste catalyst sorting apparatus used in a Residue Fluid Catalytic Cracking (RFCC) process, and to a waste catalyst sorting apparatus installed in an RFCC process for treating residues using a reactor and a regenerator. The waste catalyst screening device is installed in a catalyst input path connecting the regenerator and the reactor so that the regenerated catalyst can be re-supplied to the reactor, but a discharge pipe is installed in the catalyst input path so as to discharge the catalyst. By installing a catalyst selector for separating and discharging the catalyst according to the particle size in the outlet pipe, it is possible to increase the process efficiency by allowing the selection of the highly active catalyst to be reused through physical screening of the catalyst, Waste catalyst screening device for heavy oil catalytic cracking device that can significantly reduce the amount of catalyst used. One will.
