A PROCESS FOR SELECTIVELY HYDROGENATING BUTADIENE IN AN C4 OLEFIN STREAM CONTAINING A CATALYST POISON WITH THE SIMULTANEOUS ISOMERIZATION OF 1-BUTENE TO 2-BUTENE

摘要

A process for selectively hydrogenating butadiene that is contained in a C4 stream having a concentration of a catalyst poison and C4 olefins, includ ing 1-butene, and further the process provides for the substantial isomeriza tion of the 1-butene to 2-butene of the C4 olefin stream, wherein the proces s comprises contacting, under suitable process conditions, the C4 stream wit h a poison tolerant catalyst comprising an alumina support material and part ially sulfided nickel on the alumina support material at a concentration in the range of from 5 to 40 weight percent nickel, and yielding a product havi ng a minimal butadiene concentration and a reduced concentration 1-butene.
