Abstract
A process for the oligomerization and co-oligomerization of alpha olefins by subjecting olefins to the step of oligomerization in the presence of a supported aluminum chloride catalyst and an organoaluminum compound as a promoter. The catalyst is separated and the reaction product is subjected to the step of fractional distillation for removal of the solvent. The oligomers are further fractionated to obtain poly alpha olefins.
