Abstract
A new catalyst is disclosed which is useful for dehydrocyclizing alkanes. This catalyst contains a type L zeolite, a Group VIII metal, and an alkaline earth metal. This catalyst has been reduced in a hydrogen atmosphere at a temperature of from 480.degree. C. to 620.degree. C.
Claims21
A method of reforming hydrocarbons comprising contacting said hydrocarbons with a catalyst comprising:
- (a) a type L zeolite;
- (b) at least one Group VIII metal;
- and
- (c) an alkaline earth metal selected from the group consisting of barium, strontium and calcium, wherein said catalyst is reduced in a hydrogen atmosphere at a temperature of from 480.degree. C. to 620.degree. C.
A method of dehydrocyclizing alkanes comprising contacting said alkanes with a catalyst comprising:
- (a) a type L zeolite;
- (b) at least one Group VIII metal;
- and
- (c) an alkaline earth metal selected from the group consisting of barium, strontium and calcium, wherein said catalyst is reduced in a hydrogen atmosphere at a temperature of from 480.degree. C. to 620.degree. C.
A method of reforming alkylcyclopentanes to produce aromatics comprising contacting said alkylcyclopentanes with a catalyst comprising:
- (a) a type L zeolite;
- (b) at least one Group VIII metal;
- and
- (c) an alkaline earth metal selected from the group consisting of barium, strontium and calcium.
A method of dehydrocyclizing alkanes comprising contacting said alkanes with a catalyst at a temperature of from 400.degree. C. to 600.degree. C.;
- a LHSV of from 0.3 to 5;
- a pressure of from 1 atmosphere to 500 psig;
- and an H.sub.2 /HC ratio of from 1:1 to 10:1;
- wherein said catalyst consists essentially of a type L zeolite, an inorganic oxide binder, platinum, and barium;
- wherein said catalyst is reduced in a hydrogen atmosphere at a temperature of from 480.degree. C. to 620.degree. C.;
- wherein said catalyst has from 0.1% to 5% by weight platinum and 0.1% to 35% by weight barium.
