Abstract
A hydrocarbon conversion process comprising contacting a hydrocarbon stream such as, for example, gasoline, with a catalyst composition to effect the conversion of the hydrocarbon to olefins and C6 to C8 aromatic hydrocarbons such as toluene and xylenes. The catalyst composition comprises a zeolite, a promoter and optionally a binder.
Claims22
A process comprising contacting a fluid which comprises a hydrocarbon with a catalyst composition under a condition sufficient to effect the conversion of a hydrocarbon to an olefin and a C6 to C8 aromatic hydrocarbon wherein said catalyst composition comprises a ZSM-5 zeolite and a promoter selected from the group consisting of zinc titanate, zinc silicate, zinc aluminate, and combinations of two or more thereof wherein said composition is a steam-treated composition.
A process comprising containing a fluid which comprises at least one saturated hydrocarbon with a catalyst composition at to effect the conversion of a hydrocarbon to an olefin and a C6 to C8 aromatic hydrocarbon wherein said catalyst composition a ZSM-5 zeolite, silica, and a promoter selected from the group consisting of zinc aluminate, zinc silicate, zinc titanate, and combinations of two or more thereof wherein the weight ratio of silica to zeolite is in the range of from about 1:7 to about 5:1;
- and the weight ratio of promoter to zeolite is in the range of from about 0.1:1 to about 0.5:1.
A process comprising contacting a fluid which comprises at least one saturated hydrocarbon with a catalyst composition under a condition sufficient to an olefin and a C6-C8 aromatic hydrocarbon wherein said catalyst is produced by the steps comprising:
- (1) combining a ZSM-5 zeolite, a binder, and a promoter selected from the group consisting of zinc aluminate, zinc titanate, zinc silicate, and combinations to two or more thereof, under a condition sufficient to produce a modified zeolite;
- and
- (2) steaming said modified zeolite.
