Catalytic Performance of La-Ni/Al2O3 Catalyst for CO2 Reforming of Ethanol

La-promoted 10%Ni/Al2O3catalyst was prepared by wet impregnation method and evaluated for ethanoldry reforming at various reaction temperatures and partial pressure of reactants. Ni particles were finelydispersed on catalyst surface and catalyst exhibited surface area of about 86 m2g−1. X-ray diffra...
