Characterization of Ni catalyst supported on α-Al2O3 and SiO2 for syngas production via dry reforming of glycerol

Ni-based catalysts supported on α-Al2O3 and SiO2 were prepared through wet impregnation method for glycerol dry reforming to produce hydrogen, carbon monoxide and methane. Glycerol dry reforming was carried out in tubular reactor at 973 K under atmospheric pressure. The catalysts were characterized...
