ABSTRACT

The purpose of this study is to obtain activated carbon adsorbent with good carbon dioxide adsorption performance by pyrolysis of waste polyurethane, and solve the two problems of environmental pollution and carbon dioxide emission of waste polyurethane. At 600℃, the waste polyurethane was carbonized with urea and activated with KOH at 800℃. The obtained product has large specific surface area, pore size of 0.5nm-1nm, and good adsorption capacity of UC-5-1.5, which is 6.5mmol/g at 1 bar at 0℃. In this study, foam polyurethane was used as raw material, nitrogen was doped by mixing different nitrogen sources and activated by KOH to obtain porous carbon adsorbent. The prepared adsorbent has larger specific surface area and higher carbon dioxide adsorption capacity.
