Abstract
A layered catalyst is disclosed for use in transalkylation of polyalkylated benzenes. The catalyst comprises an inner core material with a molecular sieve bonded over the core. The process minimizes the cracking of the alkyl groups during the transalkylation reaction.
Claims8
An aromatic transalkylation process comprising:
- passing a first stream comprising an aromatic substrate hydrocarbon and a second stream comprising an aromatic hydrocarbon having more than one alkyl group to a reaction zone, wherein each alkyl group has 6 or more carbon atoms;
- reacting the aromatic hydrocarbon in the first stream with the polyalkyl aromatic hydrocarbon in the second stream over a solid catalyst comprising a layered structure, thereby generating an effluent stream comprising a monoalkylated aromatic hydrocarbon.
