Influencing mechanism of Fe2+ on biomethane production from coal

The conversion of coal to biomethane is gaining considerable attention and can play a significant role in the field of energy research. To study the underlying influencing mechanism of adding exogenous Fe2+ on the process of the conversion of coal to biomethane, the biomethane production experiments were conducted using lignite and bituminous coal A as the substrate, and supplemented by different concentrations of ferrous ions. It is found that...
