Biomass to hydrogen-rich syngas via tar removal from steam gasification with La1-XCeXFeO3/dolomite as a catalyst

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% La 1-X Ce X FeO 3 /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 LaFeO 3 , temperature on the product were examined. Ce-substitution boosted the activity of LaFeO 3 /DOL according to the data. Among the prepared catalysts, La 0.8 Ce 0.2 FeO 3 /DOL performed the best, yielding a greater H 2 production and tar with a higher naphthalene concentration. As the temperature rises, so does the H 2 yield, at 850 °C, the highest H 2 yield is 0.69Nm 3 /Kg. Furthermore, the aromatization of phenols in tar is more likely to occur at high temperatures.
