Method for producing a supported hydrogenation catalyst having increased hydrogenation activity

摘要

In a process for preparing a supported hydrogenation catalyst with increased hydrogenation activity, which comprises a hydrogenating metal and/or an oxide of a hydrogenating metal on an Al2O3-containing support material, said calcined supported hydrogenation catalyst is treated before or after the final shaping thereof and before use thereof in the hydrogenation with a base solution having a pH of >10 at a temperature in the range from 20 to 120° C. for 1 to 300 hours.

1. A process for preparing a supported hydrogenation catalyst with increased hydrogenation activity, which comprises a hydrogenating metal and an oxide of a hydrogenating metal on an Al2O3-containing support material, said calcined supported hydrogenation catalyst being treated before or after the final shaping thereof and before use thereof in the hydrogenation with a base solution having a pH of >10 at a temperature in the range from 20 to 120° C. for 1 to 300 hours, and wherein an oxidic material comprising copper oxide and aluminum oxide and at least one of the oxides of iron, lanthanum, tungsten, molybdenum, titanium, zirconium, tin or manganese is provided, pulverulent metallic copper, copper flakes, pulverulent cement, graphite or a mixture thereof is added to the oxidic material and the resulting mixture is shaped to a shaped body.
