Catalyst and process for isomerizing olein from olefin-containing hydrocarbon-based mixtures having 4 to 20 carbons

摘要

The present invention is a catalyst comprising alumina as a support material and palladium or platinum as an active component, a) impregnating an alumina support with a solution containing at least one salt of palladium or platinum as an active component; b) drying the catalyst thus obtained, c) the catalyst thus obtained with hydrogen or a mixture of hydrogen and at least one inert gas for a period of 1 to 24 hours, 30 Treating at a temperature of ˜200 ° C., and d) then treating the catalyst thus reduced in the presence of hydrogen or a mixture of hydrogen and at least one inert gas for 1 hour to 10 days, The catalyst obtained by the process hold | maintained at the temperature of -100 degreeC is provided. The catalyst provided by the present invention is a process for the isomerization of olefins from olefin-containing hydrocarbon-based mixtures having 4 to 20 carbon atoms at a temperature of 10 to 150 ° C. and a pressure of 1 to 35 bar. Useful.
