    • Disclosed is a fluid catalytic cracking system in which the catalytic cracking reaction takes place in a dilute phase region (3), and the reaction product contains a reduced volume of off gas having a low concentration of SOx and NOx. The use of off gas, which is produced during a regeneration step, to strip entrained vapor from spent catalytic cracking catalyst acts to reduce SOx and NOx byproducts, and eliminates the need to separately recover and treat the off gas stream from the regenerator portion of the system. The entire process, including the reaction step, the stripping step and regeneration step, can be performed in a non-partitioned vessel in the dilute phase reaction (3), stripping (6) and regeneration (9) regions, respectively.
    • 公开了一种流化催化裂化体系,其中在稀相区(3)中进行催化裂化反应,反应产物含有SO x和NOx低浓度的废气体积减少。 使用在再生步骤中产生的废气从废催化裂化催化剂中除去夹带的蒸汽起到减少SO x和NO x副产物的作用,并且不需要单独回收和处理来自废催化裂化催化剂的再生器部分的废气流 系统。 包括反应步骤,汽提步骤和再生步骤在内的整个方法可以分别在稀相反应(3),汽提(6)和再生(9)区域的非分隔容器中进行。
