Hydrogen Production via Glycerol Dry Reforming Over La-NiAl2O3 Catalyst

Glycerol (a bio-waste generated from biodiesel production) has been touted as a promising bio-syngas pre-cursor via reforming route. Previous studies have indicated that carbon deposition is the major perform-ance-limiting factor for nickel (Ni) catalyst during glycerol steam reforming. In the curre...
