As a renewable energy source, methane can not only improve ecological benefits and save energy, but also bring good economic benefits. In order to enhance the efficiency of methane preparation, the author used sodium acetate as the base material to study the effect of various mineral materials on microbial methane preparation. The results showed that mineral materials with good conductivity play a positive role in anaerobic microbial methane preparation, which is of referential meanings to highly-effective CH4 preparation.
