  • Process for the preparation of supported aluminium chloride catalyst containing organo aluminium compound
    Patent number: 6096678
    Abstract: A process for the preparation of an inert oxide supported metal halide organo aluminium compound catalyst. The catalyst is obtained by reacting an activated support having surface hydroxyl groups with aluminium chloride selected from aluminium chloride solution and aluminium chloride vapors. A solution of an aluminium alkyl is added to the reacted support. The solvent is removed and the reacted support is dried.

  • Process for oligomerisation of alpha-olefins
    Patent number: 6002060
    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.
