Catalysts and catalyst supports, with inorganic nitrates, for olefin dimerization.

摘要

This invention concerns catalyst systems for olefin dimerization wherein said catalyst system comprises at least one elemental alkali metal catalyst, supported on an alkali metal carbonate support, wherein said support includes an inorganic nitrate. This invention further concerns processes for the dimerization of olefins. The catalytic support can optionally comprise a carbonaceous compound(s), an inorganic oxide(s), or a mixture thereof. Furthermore, the catalyst system optionally can comprise at least one promoter selected from the group consisting of elemental copper, elemental cobalt, finely divided stainless steel, finely divided glass, or mixtures thereof.
