Abstract:
Syngas production from catalytic co-gasification of biomass from bagasse and ethanol was investigated in a fixed-bed reactor at atmospheric pressure. The effects of the reaction temperature, ethanol content in gasifying agent and NiO/MgO/Al2O3 on gas composition were studied. The results indicated that when increasing the temperature to 800 ° C, the greatest yield of producer gas in the absence of additive and catalyst was found. It was found that the addition of ethanol in co-gasification with bagasse gave a positive effect on the yield of producer gas consisting of hydrogen, carbon monoxide and methane. From the economic point of view, addition of 10% ethanol by volume would be the most suitable. Therefore, ethanol solution before purification from biomass fermentation can be used in the co-gasification. Furthermore, the presence of NiO/MgO/Al2O3 catalyst can enhance the decomposition of tar and increase the yield of producer gas.
