A commercially available activated carbon was used to prepare active carbonviareactivation with KOH at 750°C. Active carbon was obtained with 60.5% yield. The resulting active carbon showed a well-developed porous structure with specific surface area 2939 m2/g, total pore volume 1.488 cm3/g, and micropore volume 1.001 cm3/g. Process reactivation of carbon changes its particle size as well as density properties and increases by nearly twice the amounts of methane and carbon dioxide adsorbed under high pressure conditions. Such active carbon may be used to enrich methane or carbon dioxide by pressure swing adsorption technique. Other possible applications of reactivated carbon are storage of hydrogen and methane and sequestration of carbon dioxide.

Adsorption Capability

Adsorption characteristics of nitrogen and oxygen onto the ion-exchanged X-type zeolites through pressure swing adsorption (PSA) process were investigated. On the basis of Na-X zeolite, a series of ion-exchanged X-type zeolites containing Ag, Li, Ca, Sr, Br, and K were prepared and investigated in this work. It was revealed that the ion-exchanged X-type zeolites showed a remarkably improved and selective adsorption capability for nitrogen. At equilibrium pressure under 0.5 atm, adsorption capability for nitrogen was decreased in the order of Ag-X > Li-X > Sr-X > Ca-X > Na-X > Ba-X > K-X. At equilibrium pressure over 1 atm, however, the capability was decreased in the order of Li-X > Ag-X > Sr-X > Ca-X > Na-X > Ba-X > K-X. The Li-X zeolite exhibited the selective adsorption capability for nitrogen in the air separation process at high pressure. The separation factor for nitrogen/oxygen (= N2/O2) in the Li-X zeolite was ca. 13.
