| Abstract: | NiMgAl hydrotalcites were synthesized by coprecipitation method,and the effects on the catalytic properties had been studied by different dying method.The hydrotalcites and derived mixed oxides were characterized by XRD,TPR,TPD,TG-DSC and BET.The results showed that the samples obtained by microwave drying had a relatively high surface area,a higher reduction temperature,an enhanced CO2 adsorption capacity,and the active component could form a strong interaction with the Mg/Al oxides.Besides,samples dryed by microwave had a better catalytic performance in CO2 reforming CH4,including improved catalytic activity and high stability. |
