摘要This study presents the preparation of a 1Mo3Ni1Co/Cor catalyst by vacuum impregnation to obtain a clean biomass gasification product gas. The effects of the air equivalence ratio (ER) and catalytic temperature on tar cracking and gas reforming were investigated. The regeneration activity of the 1Mo3Ni1Co/Cor catalyst was also evaluated in biomass gasification. Results show that the choice of ER is highly important, and an increase in catalytic temperature is favorable for cleaning biomass gasification raw gas. When the ER and catalytic temperatures were 0.21 and 800 degrees C, the gas yield, tar conversion, and hydrogen yield reached 1.28 N m(3)/kg, 99.2%, and 49.3 g/kg, respectively. The regeneration activity of this catalyst is relatively stable and close to that of the fresh catalyst after a 4 h reaction; however, this activity is relatively lower than that of the fresh catalyst in the initial stage. This difference is caused by the formation of Mo2C in gas reforming. Finally, the activation energy and the pre-exponential factor of the catalyst calculated by first-order reaction kinetics model are 33.79 kJ/mol and 523 s(-1), respectively.
