Patent ID: 7053258

Claim:
A process for producing para-xylene from a feedstock enriched in at least one C 8 isoalkene component comprising: (a) contacting said feedstock with a dehydrocyclization catalyst under conditions of temperature and hydrogen partial pressure sufficient to effect dehydrocyclization, said catalyst comprising a molecular sieve having an alpha value less than about 10, a channel size in the range of about 5–8 angstroms, a 10- to 12-membered ring-structure consisting essentially of oxides of at least two elements selected from the group consisting of Si, Al, P, Ge, Ga and Ti, and further containing at least one Periodic Table Group VIII metal; and (b) recovering a reformate rich in at least one of benzene, toluene, para-xylene and ethylbenzene, wherein said molecular sieve is selected from the group consisting of zeolite *BEA, ETS-10, and, ETAS-10, wherein said C 8 isoalkene component is 2,5-dimethylhexene, 2,5-dimethylhexadiene, 2,5-dimethylhexatriene or a mixture thereof.
