This layout is derected against reaction and regeneration system to compute.A high efficient and complete coke burning regenerator having high burning capacity was adopted because much coke was produced during RFCC process.In the design, Referring to the dates of feed and the same type reactors, I design a high-low parallel FCC reactor-regenerator system-riser reactor and coke container high temperature complete reactor-regenerator system. The part of reaction: the reactor develops sufficient room for feed oil and catalytic...
