Effect of Vacuum Process on Enrichment of Low-Concentration Coal Mine Methane by Adsorption
The massive emission of low-concentration coal mine methane (CMM) has resulted in the ineffective utilization of a large amount of energy methane and caused environmental pollution.The gas mixture used in the study consisted of methane (CH4) 12% and nitrogen (N2) 88%.The adsorbent was coconut activated carbon.This paper uses teclado newskill blanco
