ABSTRACT:
Olefinic feedstocks which contain catalyst contaminants or poisons such as sulfur containing compounds may be oligomerized to a desired product by effecting the reaction in the presence of an added amount of hydrogen to the feedstock. The catalyst which is employed to effect this oligomerization will remain stable and will not deactivate due to the presence of the aforementioned poisons. The catalyst composite will comprise a porous support which has been impregnated with a catalytically effective amount of an iron group metal compound and, if so desired, a compound containing a metal of the Group IVA of the Periodic Table. In addition, the catalyst composite will also contain in combination therewith, a catalytically effective amount of an alkyl aluminum compound and, if so desired, an aluminum alkoxy or aluminum halide compound.
