A system including enriching coal bed methane by solar energy and selective catalytic reduction

Besides, a new SCR of NOx by CH4 with catalyst La0.8Sr0.2MnO3 is presented in this paper and the enriched CH4 is the reducing agent. Experiments were done to investigate the efficiency of the new catalyst. In the new CH4-SCR system, the maximum conversion ratio of NO can reach to 80% and the mass concentration of NO at the outlet can be lower than 20 mg/m3 in a proper condition. This new system can make good use of the solar energy to enrich CBM and present an efficient way to use the enriched CBM, which is friendly to the environment.
