Estimating the term…
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.
A catalyst for the selective hydrogenation of olefins, wherein said catalyst contains an alumina support and cobalt and/or nickel from Group VIII, molybdenum and/or tungsten from Group VIB and alkali metal components supported on said support, wherein said catalyst contains 1.4-8% by weight of cobalt and/or nickel from Group VIII, 2-15% by weight of molybdenum and/or tungsten from Group VIB, greater than 2% by weight and less than or equivalent to 8% by weight of alkali metal components, and a balanced amount of alumina support calculated as oxides and based on the catalyst;
A process for preparing a catalyst for the selective hydrogenation of olefins, which comprises contacting an alumina support with a solution containing cobalt and/or nickel from Group VIII, a solution containing molybdenum and/or tungsten from Group VIB and a solution containing alkali metal components under conditions sufficient to deposit cobalt and/or nickel from Group VIII, molybdenum and/or tungsten from Group VIB and alkali metal components on said alumina support, followed by drying and calcining;
