Description

ABSTRACT:
Oligomerization and isomerization of olefins, e.g., butene, is performed in the gas phase on a solid catalyst containing a superacid fluorine compound of an element of Group III, IV and/or V of the periodic table, e.g. Al.sub.2 O.sub.3 impregnated with a superacid or a salt thereof. e.g. HBF.sub.4, (NH.sub.4).sub.2 SiF.sub.6, H.sub.2 SiF.sub.6, NH.sub.4 BF.sub.4 or HPF.sub.6. The process is particularly applicable for increasing the olefin yield in steam cracking plants or for the recovery of fuel components from FCC residual gases.
