摘要:
An improved alkylation reactor design is disclosed. The design uses reactor effluent recycle to reduce the difference in temperature across the reaction zone improving selectivity and insuring the maintenance of a liquid phase in the reactor.
摘要:
Disclosed is a process and apparatus for alkylating light olefin with benzene at near but less than full conversion of the olefin. We have found that stopping below full conversion of the olefin maximizes yield of monoalkylbenzene.
摘要:
A process for converting polyalkylaromatics to monoalkylaromatics, particulary cumene, in the presence of a modified Y-85 zeolite is disclosed. The process attains greater selectivity, reduced formation of undesired byproducts, and increased activity.
