Copper chromite

The Adkins catalyst, a heterogeneous catalyst is composed mainly of copper, and chromium oxide dispersed on doped with metals such as barium and manganese. The catalyst developed by the American chemist Homer Burton Adkins.

Production

The catalyst ( BCAC ) are prepared Cu (OH) NH4CrO4 with subsequent drying and calcination of precipitation treatments of basic Kupferammoniumchromat. The doping can be done for example by co-precipitation of barium or other metal salts.

Application

The catalyst for the production of fatty alcohols from fatty acids or fatty acid methyl ester under a hydrogen pressure of 200-300 bar and temperatures of 150-300 ° C. Other applications lie in the hydrogenolysis of furfuryl alcohol to 1,5-pentanediol at 250-300 ° C under a hydrogen pressure of 200-400 bar and the decarboxylation of ethanol to acetaldehyde.
