Abstract
A catalyst for the selective hydrogenation of olefins especially dienes, its preparation and use, said catalyst comprising an alumina support and cobalt and/or nickel selected from Group VIII, molybdenum and/or tungsten from Group VIB and alkali metal components supported on said support, characterized in that the catalyst contains 0.5-8% by weight of cobalt and/or nickel selected from Group VIII, 2-15% by weight of molybdenum and/or tungsten from Group VIB, over 2-8% by weight of alkali metals, and a balanced amount of alumina support calculated for oxides and based on the catalyst. Compared to the prior catalysts, the activity and selectivity for olefins especially dienes of the catalyst are higher when used in the hydrogenation of a gasoline distillate.
