Abstract:

Tar, a by-production from biomass gasification, is a main obstacle that hinders the development of biomass gasification. The main methods of tar removal from gasified biomass can be classified into physical and chemical methods. The catalysts of biomass pyrolysis for hydrogen production were summarized. The catalytic ability, reaction mechanism and performance evaluation of Fe-based catalysts with different oxidation states were analyzed. Then, the influence of oxygen potential, carrier type and interaction between carriers and Fe catalyst on Fe-based catalyst was summarized.The new chemical looping gasification technology was introduced.The performance of Fe-based oxygen carrier in biomass chemical looping gasification and the performance of the new composite Fe-based oxygen carriers added with La, Mn, Ni and other elements were analyzed. The research direction of Fe-based catalysts is made.

Key words: biomass gasification, tar, Fe-based catalyst, biomass chemical looping gasification, carbon neutrality, catalytic activity, steam reforming, hydrogen production
