该烃原料的流化催化裂化工艺包括：①在提升管反应器的催化剂密相段中反应；②大量的催化剂与烃产品分离，气态烃夹带少量催化剂；③在汽提段中除去夹带的催化剂颗粒；④使用汽提介质汽提富集于从步骤②分离的催化剂上的挥发性烃，形成汽提过的再生剂、汽提介质和烃物流；⑤烃
The fluid catalytic cracking process of the hydrocarbon feedstock comprises: (i) reaction in the catalyst dense phase of the riser reactor; (ii) separation of a large amount of catalyst from the hydrocarbon product, entrainment of a small amount of catalyst by the gaseous hydrocarbon; (iii) removal of the entrained catalyst in the stripping section Particles; (4) stripping the volatile hydrocarbon enriched in the catalyst separated from step (2) using a stripping medium to form stripped regenerant, stripping medium and hydrocarbon stream;
