【摘要】
A kind of new catalyst—carbonaceous catalyst—for CH4-CO2 reformation has been developed in our laboratory. The effect of both oxygen-bearing functional group such as phenolic hydroxyl, carbonyl, carboxyl, and lactonic, and ash such as Fe2O3, Na2CO3, and K2CO3 in the carbonaceous catalyst on the CH4-CO2 reforming has been investigated with a fixed-bed reactor. It has been found that the carbonaceous catalyst is an efficient catalyst on CO2-CH4 reforming. With the decrease of oxygen-bearing functional group, the catalytic activity of carbonaceous catalyst decreases quickly. The oxygen-bearing functional groups play a significant role in the carbonaceous-catalyzed CO2-CH4 reforming; the ash components in carbonaceous catalyst also have an important influence on the CO2-CH4 reforming. Fe2O3, Na2CO3, and K2CO3 in the ash can catalyze the CO2-CH4 reforming reaction; CaO has little effect on CO2-CH4 reforming reaction. CaO can catalyze the gasification between carbonaceous catalyst and CO2; Al2O3 and MgO inhibit the CO2-CH4 reforming.
