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.
Claims9
In a method for catalyzing formation of an alkylate from a feed comprising an olefin and a branched alkane, the improvement comprising using as catalyst an acid catalyst 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% under appropriate reaction conditions that substantially preclude a temperature treatment of said acid catalyst in excess of about 450.degree. C.
In a method for catalyzing reaction of an olefin with a branched alkane, the improvement comprising using as catalyst an acid catalyst 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% under appropriate reaction conditions that substantially precludes a reaction temperature in excess of about 450.degree. C.
