A　new　type　of　benzene　adsorption　material　was　prepared　by　using　the　airtight　heat　treatment　method.　This　method　can　directly　transform　the　organic　impurities　of　the　activated　alumina　waste　into　carbon　with　adsorption　capability.　The　microstructure　and　carbon　content　of　materials　were　characterized　by　scanning　electron　microscope　(SEM),　X-ray　diffraction　(XRD),　BET　(Brunauer　Emmett　Teller)　surface　area　analysis　and　elemental　analysis.　The　influences　of　heat　treatment　temperature　on　the　properties　of　the　composite　materials　were　discussed.　The　benzene　adsorption　capability　of　the　material　was　investigated.　The　experimental　results　show　that　the　optimal　heat　treatment　process　condition　is　airtight　heating　at　400　°C　for　2　h.　The　resulting　sample　has　carbon　mass　fraction　of　3.57%,　specific　surface　area　of　234.70　m　2/g,　pore　volume　of　0.41m3/g,　and　average　pore　size　of　6.59　nm.　The　samples　show　excellent　benzene　adsorption　capability　with　an　adsorption　rate　of　21.80%.　©　Shanghai　Jiaotong　University　and　Springer-Verlag　Berlin　Heidelberg　2012.
