Dehydroxylation of glycerol in hydrogen on Raney Co catalyst
Abstract
Dehydroxylation of glycerol in H2 atmosphere on Raney Co catalyst was studied. With temperature increasing from 140 °C to 200 °C at 30 atm H2 conversion of glycerol increased from 14 to 97 %. During 20 hours of experiment the glycerol was completely converted, the yield of 1,2-propanediol was 40 %. The maximum yield of 1,2-propanediol was 44 % and it was obtained at a 200°C temperature and a 30 atm pressure of H2. Dehydroxylation of glycerol in a hydrogen atmosphere on heterogeneous catalysts may be a perspective processing of glycerol produced as a byproduct in the production of biodiesel from vegetable oils and animal fats.
