Abstract

The research on the catalysis and kinetic mechanism of alkali metals in biomass was reviewed.The existing form of intrinsic alkali metals (k,Na) in biomass not only has a significant impact on the catalytic properties of its pyrolysis or gasification reaction,but also shows different evolution behaviors under the same pyrolysis or gasification conditions.The internal alkali metal affects the distribution and characteristics of gas production and tar composition in biomass gasification,as well as its improvement effect on biomass gasification reaction and tar decomposition.It is of great significance for the development of efficient and cheap catalysts and the efficient and clean utilization of biomass to give full play to the intrinsic catalytic properties of alkali metals.
