Energy conversation in gas separation application using carbon absorption & pressure swing adsorption (PSA) system

Various types of microporous carbon adsorbents have been prepared from Malaysia carbonaceous solid waste, the oil palm shell for the purpose of gas separations. It is an advantage to utilize the precursor by converting into useful adsorbents since it can be obtained easily and abundantly in the coun...
