Abstract
A process for selectively hydrogenating C.sub.4 -C.sub.10 diolefins to the corresponding monoolefins is carried out with a catalyst comprising (a) nickel metal and/or compound(s), (b) silver metal and/or compound(s), and (c) a solid inorganic support material (preferably alumina).
Claims20
A process for hydrogenating at least one diolefin containing 4-10 carbon atoms per molecule at a high selectivity to at least one monoolefin having the same number of carbon atoms per molecule as said at least one diolefin which comprises:
- contacting a fluid feed comprising said at least one diolefin and molecular hydrogen with a catalyst composition consisting essentially of (a) at least one nickel promoter selected from the group consisting of nickel metal and readily reducible nickel compounds, (b) at least one silver promoter selected from the group consisting of silver metal and readily reducible silver compounds, and (c) at least one solid inorganic support material,
- wherein said process is carried out at a temperature in the range of about 35.degree. C. to about 200.degree. C. so as to at least partially convert said at least one diolefin to said at least one monoolefin.

- contacting a fluid feed comprising said at least one diolefin and molecular hydrogen with a catalyst composition consisting essentially of (a) at least one nickel promoter selected from the group consisting of nickel metal and readily reducible nickel compounds, (b) at least one silver promoter selected from the group consisting of silver metal and readily reducible silver compounds, and (c) at least one solid inorganic support material,
- wherein the atomic ratio of silver to nickel in said catalyst composition is in the range of about 1:1 to about 8:1 and said process is carried out at a temperature in the range of about 35.degree. C. to about 200.degree. C., so as to at least partially convert said at least one diolefin to said at least one monoolefin.
