Abstract
Disclosed is an alkylation catalyst to form adducts or alkylates of a C.sub.3 -C.sub.9 olefin with a C.sub.4 to C.sub.9 isoparaffin comprising a sulfated mixed oxide of titanium and nickel, wherein the percent by weight of titanium is at least 80%; of nickel is in the range 1-4%; and of sulfur in the range 1-10%. Also disclosed are the appropriate ratios of olefin to isoparaffin and the use of adamantane to increase yields.
