Conversion of Products Formed in Gasification of Organic Fuels in a Flow-Through Filtration Converter with Packing

Resumo

Results are presented of experimental studies of the conversion of products formed in gasification of wood, peat, coal-wastes, and shale rock via the partial oxidation by air in a flow-through filtration converter filled with various kinds of porous packing. Charcoal ZPS zeolite and Raschig porcelain rings served as a packing. It was possible to experimentally select for all kinds of packing the modes in which the combustion heat of the conversion products is not lower than that of the starting gaseous products. The conversion of pyrolysis tars was 60–85% and depended insignificantly of the type of a packing. The experimental results were compared for products formed in gasification of wood and coal waste with the data calculated in terms of the thermodynamic conversion model. The satisfactory correspondence between the results of a thermodynamic calculation and experimental data was obtained for products formed in gasification of wood, in which the content of pyrolysis tars is rather high.
