Ni-Cu-Mo/Al2O3催化剂用于 CH4/CO2重整的研究
Reforming of CH4 with CO2 over Ni-Cu-Mo/Al2 O3 catalyst
摘要
Abstract
CH4-CO2 reforming for syngas production is a promising way for effective use of CO2 ,which is challenging from both economic and environmental points.The aim is to investigate the effect of Ni-Cu-Mo /Al2 O3 catalysts with different Ni /Mo mass ratio on the CO2 reforming of CH4 reaction.The evaluation of the catalytic performances of the composite catalysts was conducted in a fixed-bed reactor at atmospheric pressure.The influencing factors,including temperature,Ni /Mo mass ratio were investigated.The characteristics of the catalysts were characterized by X-ray diffraction (XRD),Brunauer-Emmett-Teller (BET)analysis,scanning electron microscope (SEM)and temperature-programmed desorption of CO2 (CO2-TPD).The results indicate that the catalysts with Ni /Mo mass ratio of 0.75 exhibit better activity at the optimum temperature of 800 ℃.At the reaction conditions of 800 ℃ and a space velocity of 1 82 mL/(g·min),the conversion rates of CH4 and CO2 are 97.7% and 99.1 %,respectively,and the selectivity of CO and H2 are 94.4% and 92.1 %,respectively.关键词
