Abstract:

This review discussed the influence of promoters in terms of catalyst performance, physical and chemical properties as well as deactivation characteristics of catalyst from the perspective of alkali and alkaline earth metals, transition metal and rare earth metal, respectively.After the addition of alkali metal components, the biomass pyrolysis reaction rate will increase significantly, the steam gasification reaction of biomass coke will be promoted, and the temperature required to achieve the maximum pyrolysis rate will also decrease, the pyrolysis products tend to be small molecular weight products. The transition metal has good catalytic activity to the catalytic cracking reforming of tar in the gasification process. Rare earth elements play an important role in catalytic reactions such as methanol steam reforming. The addition of Ce and Pr in nickel-based catalysts can improve methanol conversion, gas-producing components and H2 selectivity. Combined with the domestic and foreign research, it is found that Co, La and other metal promoters are conducive to improving the hydrogen production activity of nickel-based catalyst, while carbon deposition and active particles aggregation are the main causes of catalyst deactivation.

Key words: tar cracking, steam reforming, Ni-based catalyst, promoters
