Abstract
A process for selective hydrogenation of hydrocarbons is presented. The process uses a catalyst to selectively hydrogenate acetylenes and diolefins to increase the monoolefins in a product stream. The catalyst in the process includes a layered structure with an inert inner core and an outer layer bonded to the inner core, where the outer layer is a metal oxide and has at least two metals deposited on the outer layer.
Claims20
A process for selectively hydrogenating one or more C3-C11 diolefins or acetylenes in a hydrocarbon mixture to one or more respective C3-C11 monoolefins, comprising:
- contacting the hydrocarbon mixture under selective hydrogenation conditions into contact with a layered catalyst composition to give a C3-C11 monoolefin product stream, wherein the layered catalyst composition comprises:
- an inner core comprising an inert material;
- an outer layer bonded to the inner core, and comprising a metal oxide selected from the group consisting of alumina, titania, zirconia, silica, and mixtures thereof;
- a first metal deposited on the outer layer, wherein the first metal is selected from a first group consisting an IUPAC Group 8-10 metal, and mixtures thereof;
- and
- a second metal deposited on the outer layer, wherein the second metal is selected from a second group consisting of an IUPAC Group 11-17 metal, and mixtures thereof;
- wherein the atomic ratio of the first metal to the aluminum in the outer layer is in a ratio between 0.0001 and 0.1.
