Anselme payen award lecture. Chemistry of pyrolysis and of combustion of biomass
- Univ. of Montana, Missoula, MT (United States)
Thermochemical processing remains one of the most promising approaches to utilization of biomass. Yet much remains to be learned of the chemistry involved, especially for the polysaccharide components. This lecture will survey some recent advances in the understanding of the chemical mechanisms in pyrolysis of polysaccharides, especially for cellulose and hemicelluloses. The effects of trace inorganics in control of pyrolysis mechanisms will be emphasized. The effects of position and of orientation of glycosidic linkages will be considered, as will the impact of the presence of lignin. The chemical factors which influence the combustion of biomass are of importance in building fires and in forest and range fires. The volatile products (emissions) from such fires are of significance in world atmospheric and in local toxicological terms and they are considerably influenced by fuel chemistry. This combustion of biomass, especially in the smolder mode, has many features which are closely related to pyrolysis and this lecture will seek to emphasize the synergism of concepts between these two types of thermochemistry.
