150万吨/年渣油催化裂化反应再生系统工艺设计 摘 要 在本设计中，使用大庆常压渣油作为原料，采用汽油生产方案，进行渣油催化裂化反再系统的工艺设计。 催化裂化装置由反应再生系统，分馏系统，吸收稳定系统和能量回收系统组成。本设计主要针对反再系统进行设计计算。由于渣油催化裂化的焦炭产率高，对再生器的烧焦能力要求较高，故本设计选用烧焦罐式再生器以实现高效完全再生。 0.1%以下，充分发挥了催化剂的选择性，延长了催化剂的寿命。 关键词：催化裂化，提升管，再生器，催化剂 TECHNOLOGCIAL DESIGN FOR REACTION AND REGENERATION SYSTEM OF 150wt/a RFCC Abstract Reaction and regeneration system technology of a 270wt/a RFCC processing DAQING atmospheric residue feedstock has been designed and calculated in this layout. The catalytic cracking unit is made up from reaction and regeneration system fractionation system， absorption and stabilization system and energy recover system. 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，eferring 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.he part of reaction: the reactor develops sufficient room for feed oil and catalytic contacting completely. This kind of design is to reduce coke promote recall ratio of light oil. The part of regenerator system: the regenerator can burn up remaining carbon about catalytic to recover activity of CAT. General speaking， my design can reduce the ratio of carbon in CAT to 0.1%，so it makes full use of choice of CAT， extend the life of the catalyst.
