Abstract:
The disposal of crude glycerol as a by-product of the biodiesel industry is one of the major issues concerning its utilization towards the production for renewable oxygen. Among the various methods of such utilization, the Glycerol Steam Reforming (GSR) reaction has been investigated over various metal supported catalysts with Ru, Rh, Pt, Ni, Co and Fe to be active. In addition, Ni appears as the most promising active metal, due to its low cost, its ability towards O–H, C–H and C–C dissociation even more effectively than noble metals. On the other hand, apatite type lanthanum silicate (ATLS) materials, as solid oxide electrolytes, have interesting redox properties, high oxygen mobility mainly through interstitial oxygen mobility. However only scarce data is yet available on their catalytic properties although promising. In this work we report for the first time an ATLS as Ni support in the GSR reaction with promising performance in comparison with alumina supports.
