摘要：

In this study, significant effects of ionic catalysis on the formation of H-2 and CO during the steam gasification process of cellulose are revealed. The energy of the C-H bonds of cellulose can be remarkably reduced by Na+ and OH- ions produced by the dissociation of NaOH, enabling dehydrogenation of cellulose at low temperature. Dehydrogenation of cellulose is evidently affected by the concentration of Na+ and OH- ions that cellulose can come into contact with. Higher concentrations of Na+ and OH- ions can reduce the initial dehydrogenation temperature of cellulose to lower than 403 K. The production of CO increases after this remarkable dehydrogenation of cellulose, which indicates that the C-O bonds of cellulose are prone to forming CO by pyrolysis. (C) 2010 Professor T.
