Abstract
The invention concerns a process for the removal of catalyst residues from a gas by contacting the gas with particulate mineral oxides. The process of the invention may be applied to the removal of coordination catalyst residues from .alpha.-olefins recycled from a polymerization reactor. The process is particularly useful in the removal of alkylaluminium halides and hydrogen halides, such as diethylaluminium chloride and hydrogen chloride, from .alpha.-olefins such as propylene. The process offers the advantages of being able to be operated under anhydrous conditions, and combining high efficiency in the removal of low levels of catalyst residues with a high capacity for the catalyst residues.
