Abstract
A catalyst for selective hydrogenation of hydrocarbons is presented. The catalyst selectively hydrogenates acetylenes and diolefins to increase the monoolefins in a product stream. The catalyst 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.
Claims19
A catalyst for selective hydrogenation comprising:
- a layered structure having an inner core comprising an inert material;
- an outer layer bonded to the inner core, comprising aluminum oxide and a metal oxide selected from the group consisting of gamma alumina, delta alumina, eta alumina, theta alumina, silica-alumina, zeolites, nonzeolitic molecular sieves, titania, zirconia, 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 0.001 and 0.005, wherein the atomic ratio of the second metal to the first metal is less than 6.
