英文摘要: Hydrogenolysis of glycerol to 1, 2-propanediol was investigated on bi-functional Co/MgO catalysts where the interaction between cobalt species and MgO was adjusted by varying the temperature of calcination. Higher temperature treatment not only enhanced the interaction between Co(3)O(4) and MgO, but also promoted the formation Of MgCo(2)O(4) spinel and Mg-Co-O solid solution. Although the reducibility of cobalt oxides was greatly decreased in the Co(3)O(4)/MgO precursor, this strong interaction prevented the aggregation of Co particles in the resulting Co/MgO catalyst under the harsh reaction conditions, giving a much higher activity and stability. Results revealed that MgO was hydrated to Mg(OH)(2) during the course of reaction and that the sizes of Mg(OH)(2) and Co particles increased considerably, especially during the initial stage of the reaction.
