Development of biological coal gasification (MicGAS process). Nineth quarterly report, [July--September 1992]

Technical Report · Fri Oct 30 00:00:00 EST 1992

Laboratory scale studies examining biogasification of Texas lignite at various coal solids loadings have been completed. Bench scale bioreactors are currently being used to scale up the biogasification process to higher coal solids loadings (5% and 10%) Specific observations reported this quarter are that methane production was not curtailed when B-vitamin solution was not added to the biogasification medium and that aeration of Mic-1 did not sufficiently oxidize the medium to eliminate strict anaerobic bacteria including methanogens.
