ABSTRACT:
This invention relates to a process for treating olefinic hydrocarbon mixtures with a catalyst system comprising an admixture of a disproportionation catalyst comprising an element selected from the group consisting of molybdenum, tungsten, rhenium and mixtures thereof, and optionally cobalt, and an isomerization catalyst prepared by impregnating a porous alumina support with a metal compound decomposable to an oxide upon calcination wherein said metal is selected from the group consisting of potassium, rubidium, cesium and mixtures thereof and subsequently calcining the resulting material at a temperature of from about 450.degree. C. to about 750.degree. C., thus producing increased yields of detergent range, i.e., C.sub.10 -C.sub.16, olefins.
