The overall objective of the program is to develop a process for the conversion of peat to substitute natural gas (SNG) and to evaluate its process economics. All the laboratory-scale tests had been completed during an earlier report period, and a preferred reactor configuration for gasifying peat had been selected. The PDU tests now in progress will help establish the peat gasification process yields and process economics. The following three major milestones were reached this month: hydrogasification tests with a synthesis gas were initiated, and a successful test was conducted. All previous tests were conducted with either hydrogen or steam-hydrogen mixtures; the commercial reactor concept incorporates peat hydrogasification with synthesis gas. Sinter-free operation was achieved during peat char gasification in the fluidized-bed with steam and oxygen at 1835/sup 0/F with a superficial gas velocity of 0.83 ft/s. The previous char gasification test, conducted at 1815/sup 0/F, resulted in ash sintering when operated at a 0.48 ft/s gas velocity. In comparison, the commercial reactor concept incorporates char gasification in a sinter-free fluidized bed with steam and oxygen at 1850/sup 0/ to 1950/sup 0/F. Work was initiated on evaluating the process economics of converting peat to SNG. This work was related to evaluating alternative systems for feeding peat to a gasifier at 500 psig.
