| 摘要 |
An alkylating agent alkylates an alkylation substrate in a solid catalyst alkylation process in which an alkylation reactor produces a reaction efflue nt and a catalyst regeneration zone produces a hydrogen-containing regeneration effluent. The alkylation effluent passes to an alkylate fractionation zone, while the regeneration effluent passes to a hydrogen fractionation zone to remove hydrogen and produce a hydrogen-depleted stream that passes to the alkylate fractionation zone. The process recycles hydrogen, and can recycle halogen-containing species as well, within the process while preventing admixture of hydrogen with the alkylating agent. This invention is particularly applicable to alkylation processes that use an olefinic alkylating agent. |
