%X Effect of alkali metal K on the hydrogasification of lignite was studied in a pressurized fixed-bed reactor,and the effects of temperature,pressure and catalyst loading on the reactivity of hydrogasification of lignite coal were examined.The experimental results show that the alkali metal K has a superior catalysis on the hydrogasification of lignite,and the carbon conversion of hydrogasification and the methane content in gaseous products can be up to 95% and 89%,respectively.The gasification reactivity can be enhanced obviously by increasing temperature,pressure and catalyst loading,and the catalyst loading saturation level is about 15%.The surface morphology and pore structure of coal samples with different catalyst loadings have been analyzed using scanning electron microscope(SEM) and gas adsorption/desorption analysis,which indicates that the specific surface areas and total pore volume decrease initially,and then increase with the increasing of catalyst loading.
