Abstract
Biomass gasification produces hydrogen, which is a clean and promising technology. One of the most important aspects of the biomass gasification process is choosing the right catalyst. In this study, 10% La1-XCeXFeO3/Dolomite (X = 0,0.2,0.4,0.6,0.8) synthesized using the sol-gel method was used as a catalyst in biomass gasification for the production of hydrogen-rich syngas. Gasification tests were carried out in a fixed bed reactor. The effects of an elemental substitution in LaFeO3, temperature on the product were examined. Ce-substitution boosted the activity of LaFeO3/DOL according to the data. Among the prepared catalysts, La0.8Ce0.2FeO3/DOL performed the best, yielding a greater H2 production and tar with a higher naphthalene concentration. As the temperature rises, so does the H2 yield, at 850 °C, the highest H2 yield is 0.69Nm3/Kg. Furthermore, the aromatization of phenols in tar is more likely to occur at high temperatures.
