During this reporting period preliminary data were taken for the kinetic models necessary for a peat biogasification process. A limited number of batch experiments were conducted to obtain rate data for the solubilization kinetic model. The analysis of the pretreatment batch tests was slowed down this quarter because the High Pressure Liquid Chromatography (HPLC) solvent system was altered. This was done because a mass balance around the HPLC with the solvent system (85% H/sub 2/O/15% acetonitrile) was incomplete. The preliminary data indicate that the new solvent system developed seems to be acceptable. Pretreated peat, both oxidized and unoxidized, has been fermented to fuel gas with conversions up to 20%. The fermentation experiments show that oxidation temperature has little effect on anaerobic digestion. Continuous digesters were set up to obtain rate data for the fermentation model. Preliminary process models were developed for the three phases of peat biogasification, namely, solubilization, oxidation, and fermentation. Rate data for the solubilization phase were taken, but more is needed to develop the model further.
