摘要 不熔化沥青球在低速流化床中炭化和活化的初步研究乔文明,王克温,凌立成,刘朗周承泽,王瑾,郑斌(中国科学院山西煤炭化学研究所,太原030001)(上海太平洋化工(集团)公司焦化总厂,200241)关键词低速流化床,活化,炭化,球形活性炭由于球形活性炭,... In a fluidized bed, the stabilized pitch spheres,which were prepared from coal tar pitch,were carbonized,then activated with water vapor.Pitch based spherical activated carbon(PSAC) with specific surface area of 1000-2000m2/g was finally obtained.The effects of activation temperature,activation time as well as composition of activating agent were investigated.The elemental analysis,surface area and pore size of PSAC were determined.Its adsorptive property was preliminarily studied.
