Abstract
This invention relates to a catalyst system comprising (a) at least one layer of a first catalyst comprising a dehydrogenation active metal on a solid support; (b) at least one layer of a second catalyst comprising a metal oxide; and (c) at least one layer of a third catalyst comprising a transition metal on an inorganic support; wherein the at least one layer of a second catalyst is sandwiched between the at least one layer of a first catalyst and the at least one layer of a third catalyst; and a process comprising contacting a hydrocarbon feed with the catalyst system.
Claims19
A catalyst system comprising:
- (a) at least one layer of a first catalyst comprising a dehydrogenation active metal selected from the group consisting of platinum, palladium, iridium, chromium, and mixtures thereof on a solid support;
- (b) at least one layer of a second catalyst comprising magnesium oxide, calcium oxide, or a mixture thereof;
- and
- (c) at least one layer of a third catalyst comprising a transition metal on an inorganic support;
- wherein the at least one layer of a second catalyst is sandwiched between the at least one layer of a first catalyst and the at least one layer of a third catalyst.
