Abstract:
Gasification is a promising way to convert biomass into synthetic petroleum via Fischer-Tropsch synthesis as well as into electricity through ulitization of engine and turbine. However, tar-free clean gasification is required for the establishment of the reliable gasification systems, because tar-by products cause various trouobles such as pipeline colgging, catalyst deactivation, and engine damage. A better understanding of the chemistry involved in biomass gasification would provide insights into the strategy for the mitigation of the tar problems. This paper summarizes our recent investigations on the vapor-phase reactions and their roles in cellulose gasification, mainly based on the experimental and theoretical investigations of the vapor-phase reactivity of levoglucosan as an important intermediate of cellulose gasification. Levoglucosan was selectively fragmented into gaseous products including CO and H2 via smaller amounts of C1-C3 carbonyl intermediates, and any furans, benzenes, and coke were not proeduced. Thus, the vapor-phase reactions of levoglucosan are clean for tar and coke by-production, which are produced only via the molten-phase reactions.
