Preparation of Syngas by Reforming of Biological Glycerol on Charcoal Catalyst

Preparation of syngas by reforming of biological glycerol on charcoal has been studied in a fixed bed reactor. The results indicated that charcoal was a novel kind of catalyst, which not only had an active effect on the reforming process, but can decrease the cost of production. The syngas yield, glycerol conversion, and H-2/CO could reach 1.37 m(3)/kg, 76.78%, and 3.04, respectively, at the conditions of 800 degrees C, S/C of 4, WHSV of 2 h(-1). Characterizations of fresh charcoal and used charcoal were analyzed with thermogravimetry, scanning electron microscopy, and BET. The results indicated that the coke from the polymerization of glycerol might be in an amorphous state, which was the reason of the decrease of surface area and average pore size of charcoal.
