High Yield Syngas and Performance of Ni-loaded Thai Lignite Char Catalyst from Sawdust Gasification
Catalytic steam gasification of sawdust was performed with a steam pressure of 30 kPa, catalyst/biomass mass ratios of 0.5-3.0 and reaction temperatures of 500-650 °C. The Ni-loaded Thai lignite char catalyst, 15.50 wt%, was effective in catalyzing the volatile matters and tars from the devolatilize...
