Chemistry of Gaseous and Condensed Products in Coal Combustion and Conversion Systems.

摘要

A recently developed computer program, based on geometric programming, was used to evaluate the chemistry of gaseous and condensed products that arise in conversion of Illinois bituminous coal under both oxidizing and reducing conditions. Calculations of the chemistry of coal-conversion products were made for a wide temperature range of 1000 to 2000 K with air/fuel stoichiometric ratios of 0.7 to 1.3. The concentrations of all the gaseous and condensed species obtained during conversion at 1 atm pressure were correlated with temperature, air/fuel ratio, and sulfur content of the coal. Analyses provided the sulfur content among the various phases that were involved in the calculations. 40 refs., 26 figs., 12 tabs.
