Description:
The report gives results from test runs at a small pilot-scale coal gasification and gas purification facility using North Carolina peat. Results from the peat gasification are compared with those obtained previously with a New Mexico subbituminous coal. The peat gas produced had slightly more CO and CO2, while the coal gas had slightly more methane. Production of gaseous sulfur species was much less for peat, due largely to the lower sulfur content of the peat itself. Wastewater analyses showed higher concentrations of phenols and other acidic compounds and lower concentrations of PNAs in the peat-derived wastewater than in the coal-derived wastewater. Peat char remaining after gasification was depleted of As, Pb, and Hg to a greater extent than was the coal char. The peat itself contained a substantially higher Hg content than did the coal.
