Economic and kinetic studies of the biological production of farm energy and chemicals from biomass. Annual progress report, March 1979-August 1980
A system has been designed and built to test the technical and economic feasibility of producing farm energy from cellulosic residues. The system has the capacity to produPropinibactriume 1300 CF of biogas and 180 kwh per day, using four parallel batch anaerobic digesters which are agitated mechanically and heated with waste heat from the engine-generator. This system has been satisfactorily operated for a one year period utilizing native grasses as the raw material. Laboratory reactors have been operated to determine the proper inoculation ratio for starting batch cultures with cellulosic raw materials. Procedures for startup and operation of batch digestion systems have been developed and are presented. Energy and economic analyses of the operation of the test unit have been performed. Studies to determine the fertilizer potential of anaerobic digestor sludge (from agricultural residues) have been conducted. Additional studies reported include determinations of the feasibility of separating the stages of anaerobic digestion, the production of acetic and propionic acids by the micro-organism Propionibacterium acidi-propionici, the production of methane from acid hydrolyzates, and the kinetics of the continuos digestion of corn stover.
