The catalyst composition, process for the preparation of a catalyst, process for the isomerizacao dual attachment of a load olefinico aliphatic hydrocarbon and process of desproporcionamento

摘要

Catalyst composition is provided which is prepared by impregnating high surface area, high pore volume alumina with at least one magnesium compound convertible to the oxide, and, optionally, at least one alkali metal compound which is convertible to the oxide, and/or at least one zirconium compound convertible to the oxide, then subjecting the impregnated support to an oxygen-containing atmosphere under conditions suitable to convert at least a portion of the magnesium, alkali metal and zirconium compounds to the oxide form. The resulting catalyst is an effective double bond isomerization catalyst, and also greatly enhances the disproportionation activity of disproportionation catalysts when used in combination therewith.
