Development of biological coal gasification (MicGas process): 12th Quarterly report
Several experiments were conducted to study the efficiency of granulated sludge consortium (GSC) on the biomethanation of Texas lignite (TxL). With an aim of obtaining a better culture than Mic-1, GSC was used as inoculum at different concentrations. The first experiment was conducted under anaerobic conditions in 60-mL vials containing 40 mL 0.01% SNTM + 1% TxL + 10% GSC. Methane production was measured periodically in the vial headspace and after 20 days of incubation, methane was found to be up to 67 mole%. The second experiment was conducted to determine whether methane production was from biogasification of coal or from substrates used for growing the GSC. The effect of two different anaerobic conditions on biomethanation of Texas lignite was also studied.
