摘要
Abstract
Al-SBA-15 mesoporous zeolite was synthesized by grafting , and the factors that affect the product were investigated, such as ratio of silica to alumina , calcination temperature, etc.The Al-SBA-15 mesoporous zeolite was characterized by XRD , BET, FT-IR, NH3-TPD.The comparative experiments on adsorptive removal of basic nitrogen compound were performed with the obtained product Al-SBA-15 and SBA-15 under the same conditions . The results show that Al-SBA-15 retains the SBA-15 highly-ordered two-dimensional hexagonal mesostructure .Al-SBA-15 has the better nitrogen adsorption capacity than SBA-15 .When calcination temperature is 550 ℃and the atomic ratio of silica to alumina is 50,the denitrification rate of Al-SBA-15 can reach the highest 68.02%,with the adsorption capacity of 30 .6 mg/g.关键词
