ABSTRACT:
Catalytic compositions of matter which are useful in oligomerization and alkylation reactions may be prepared by treating a metal oxide support such as alumina with an aqueous solution of an acid, washing the treated metal oxide with an aqueous solution of an alkaline compound followed by drying and calcining the support. The treated support which contains added hydroxyl groups on the surface thereof is then impregnated with boron trifluoride to form the desired catalyst. The catalyst which possesses a high activity may be used at lower reaction conditions to give comparable results of conversion and selectivity.
