1·After the cracking reaction in downflow reactor, reaction products are separated and spent catalyst is directed to stripping and regeneration sections.

在下流式反应器内的裂化反应之后，分离反应产物，并将废催化剂引导到汽提与再生部分。

2·The method further separating the gas product and the trapped hydrocarbon from the spent catalyst with a stripping gas.

该方法进一步包 括用汽提气体从废弃催化剂中分离气体产品和捕获的烃。
