摘要
A kind of new catalyst—carbonaceous catalyst—for CH-CO 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 FeO, NaCO, and KCO in the carbonaceous catalyst on the CH-CO reforming has been investigated with a fixed-bed reactor. It has been found that the carbonaceous catalyst is an efficient catalyst on CO-CH 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 CO-CH reforming; the ash components in carbonaceous catalyst also have an important influence on the CO-CH reforming. FeO, NaCO, and KCO in the ash can catalyze the CO-CH reforming reaction; CaO has little effect on CO-CH reforming reaction. CaO can catalyze the gasification between carbonaceous catalyst and CO; AlO and MgO inhibit the CO-CH reforming.
