Research Abstract

Microbial conversion processes of CO2 in marine sediments were investigated by using the sediment samples obtained by the two drilling cruises. The impact of the CO2 injection to a bituminous coal was also examined by simulating in-situ pressure and temperature using a high-pressure reactor system. The results from these studies suggest that the contribution of homo-acetogenesis from H2/CO2 cannot be ignored as a CO2 conversion process.
