The report summarizes and compares results obtained from gasifying four different feedstocks in a pilot-scale fluidized-bed gasifier. Effects of operating variables (e.g., temperature, steam/carbon feed ratio, bed height, and feed rate) on carbon conversion and gas production are described. Gas compositions, expressed as mole percentages on a dry N2-free basis, showed only small differences, except for sulfur gases. No correlation of wastewater species production rates with reactor operating conditions was observed. Tar production rate was greatest for a New Mexico subbituminous coal. A coastal peat and a Texas lignite gave similar tar production rates.
