The catalytic steam gasification of palm oil wastes for hydrogen-rich gas production was experimentally investigated in a combined fixed bed reactor using the newly developed nano-NiO/??-Al2O3 catalyst. The results indicated that the nano-NiO/??-Al2O3 catalyst had greater activity for the cracking of tar in vapor and of hydrocarbons and a higher hydrogen yield than the calcined dolomite in catalytic steam gasification of palm oil wastes. Meanwhile, a series of experiments have been performed to explore the effects of temperature, steam to biomass ratio (S/B) and biomass particle size on gas co...
