Abstract

In the work presented herein, Ce-La-xCu-O catalysts with different Cu contents were synthesised using the conventional microwave (MW) method and an enhanced microwave method where air cooling (AC) during heating was applied. The catalytic materials were then studied for the steam reforming of glycerol (GSR). It was revealed that the synthesis methods (MW and AC) had an effect mainly on the degree of Cu incorporation into the Ce-La-O fluorite lattice, leading to one or two phases system. GSR tests revealed that the Ce-La-10Cu-O (AC) catalyst showed the highest glycerol conversion, conversion to gaseous products and yield of H2 (5.3 mol/mol of glycerol) and deactivated at slower rate. The improved performance of the AC catalyst can be correlated to a more homogeneous Cu incorporation into Ce-La-O mixed oxide thus forming more accessible active sites to reactants which overall impact on the catalytic performance.
