Reseatch Of The Performance Of Adsorption And Desorption Of Anthracite And Active Carbon Made From Anthracite To Mathane

This paper mainly studys the performance of adsorption and desorption to methane of anthracite and anthracite-based active carbon.In the paper,the author analyze the main factors such as temperature,pressure,humidity that influence adsorption and desorption, to find out the best adsorption and desorption conditions,guiding the choice, design and making of the methane adsorption material.The paper focus on the following.first,make NingXia TaiXI Anthracite as the adsorbent,smashing it to certain grain degree,and study the influence grain degree on the performance of adsorption and desorption .Second, base on the NingXia TaiXI Anthracite,make it into active carbon through activing,then make active carbon as the adsorbent,to study the adsorption and desorption.Third,to compare the defference of the adsorption and desorption amount between anthracite and active carbon to methane.The result shows that temperature,pressure and humidity are the mian outside factors that influence the adsorption and desorption. The adsorption ability of active is greatly better than that of anthracite,which shows that surface area,bore struture are the crutial factors that influence the adsorption and desorption of the carbon material to methane.
