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.

Abstract: Beneficiation of ilmenite using a process comprising first reducing by a known process the iron component thereof to metallic iron to form particles containing a mixture of iron and titanium oxide and then treating these particles with an iron salt or a precursor thereof, at an elevated temperature, to segregate the iron from the titanium-bearing component. The segregated iron is separated from the titanium bearing component by physical or chemical means.

Abstract: Method and apparatus for stretch-forming a hollow article from a sheet of thermoplastic material at a temperature higher than 25.degree. C. below the melting point wherein a stretching tool having at least one tip at a temperature lower than 50.degree.
