Process for wet aromatic alkylation and dry aromatic transalkylation |
摘要 |
A process for the production of alkylaromatic hydrocarbons uses a high water content in an alkylation zone and a low water content in a transalkylation zone to improve yields improve process yields and catalyst life. An aromatic feed and an acyclic feed are first passed through the alkylation reaction zone that operates at a high water content. A separator receives the effluent from the alkylation reaction zone and removes water from a sidecut of unreacted aromatic feed. The sidecut of aromatic feed and a stream of polyalkylated aromatics are contacted in the transalkylation zone. The differing water content improves the operation of both the alkylation zone and the transalkylation zone.
