Summary
Pacific Northwest Laboratory is carrying out a research project to investigate the thermochemical conversion of high-moisture biomass feedstocks to methane, hydrogen, and liquids. Experimental results obtained in FY 1985 indicate that good yields of methane-rich gas (exceeding 40% methane) can be produced. The reaction system utilizes low tempreatures (400 to 450/sup 0/C), high pressures, and a nickel/alkali carbonate catalyst mixture to effect the gasification of biomass slurries containing up to 95% water. Carbon conversions after 15 minutes have exceeded 90%. Methane yields in excess of 6 scf/dry ash-free pound of biomass have been obtained. Most of the feedstocks selected for investigation are not conventionally used in thermochemical conversion. Feedstocks which have been used to data include napier grass, sorghum stover, sunflower stalks, water hyacinths, and macrocystis kelp. Waste biomass from the food and beverage industries has also been used, as has the unconverted residue from an anaerobic digestor. In addition to gasification performance data obtained for each of these feedstocks, elemental analyses, ash contents, and moisture contents of the raw feedstocks were determined. 5 refs., 8 figs., 2 tabs.
