Abstract
Aliphatic olefinic hydrocarbons are isomerized in the presence of a catalyst consisting essentially of elemental chromium or a chromium compound and an aluminum phosphate support wherein the phosphorus/aluminum atomic ratio of the support is less than 1.
Claims7
A process for the double bond isomerization of an aliphatic olefinic hydrocarbon feed which comprises contacting said feed under isomerization conditions with a catalyst consisting essentially of:
- (a) 0.1-10 wt.% of elemental chromium or a chromium compound, calculated as chromium metal and based on the total weight of chromium and support, and
- (b) an aluminum phosphate support wherein the phosphorus/aluminum atomic ratio of said support is less than one.
