Abstract

This invention relates to a catalyst composition capable of effecting selective oligomerisation of olefins contained in cracked refinery distillate streams, comprising of olefins, aromatics, paraffins and cycloparaffins. The catalyst composition gives very high conversion of olefins to poly olefins, which after distillation and stabilization by hydrogenation affords lubricating oil base stocks. The catalyst composition comprises of an aluminum halide and a transition metal alkoxide belonging to group IVB.
