摘要： In this study, we prepared Fe or/and K doped biochar for catalytic reforming of rice husk pyrolysis vapors in a two-stage fixed-bed reactor. Among these catalysts employed, Fe-K bimetallic doped biochar RHC@Fe/K was found to have excellent catalytic activity and stability, which exhibited high selectivity for H2 production and the best carbon deposition resistance during reforming process. The H2 yield of 23.78 mmol/gbiomass and the H2/CO ratio of 4.15 were obtained by using RHC@Fe/K as catalyst. The doping sequence of Fe and K affected the structure of biochar, leading to the difference in catalytic performance. The mechanism of RHC@Fe/K to promote H2 production including mesoporous and highly porous formation, it-it coupling to enhance the adsorption of tar, potassium inducing high density of Fe oxides, oxygen vacancies adsorbing hydroxyl radicals (& sdot;OH) were summarized. Overall, this research developed an efficient Fe/K bimetallic doped biochar to produce H2-rich gas.
