Simulation study on the biological methanation of CO2 sequestered in coal seams

The technologies for the bioconversion of CO2 to CH4 by microorganisms are clean and safe and have attracted extensive attention in the field of energy conservation and emission reduction in recent years. A series of biological gas production experiments were carried out using bituminous coal D and indigenous bacteria from the Qianqiu coal mine, with the addition of NaHCO3 to simulate CO2 sequestration in coal seams, to explore the feasibility...
