| 摘 要： | The coal-bed gas was usually extracted from mine in order to avoid coal gas outburst.The Methane(CH4),a main component in coal-bed gas,is a kind of excellent gas fuel and raw material for chemical industry.China is very rich in the resource of coal bed gas,however,most of the coal bed gas extracted from mine is wasted because of the too low concentration of methane. Pressure sweep adsorption(PSA) technique is noticeable among the methods for the concentration of methane from coal-bed gas.However,there are a few studies about this field.Studies on the pressure sweep adsorption(PSA) process for the separation of CH4/N2 using actived carbon as adsorbent are summarized.The thermodynamic relationships and kinetic processes and the influence of the operate parameters on the concentration of methane are investigated.These results have a direct application in coal-bed gas.Some suggestions for the problems need to be solved in PSA process for the separation of methane are also proposed.
