| 摘 要： | 采用模板法水热合成介孔沸石材料,通过N2吸附-脱附,扫描电子显微镜对样品进行表征。试验分别考察了模板剂种类和添加扩孔剂(TMB)等因素对介孔沸石材料制备的影响。试验结果表明:采用三嵌段共聚物(简称P123)复合啤酒酵母作为模板剂,强酸性体系下置于不锈钢反应釜内晶化,制备样品的平均孔径可达到3.38nm,并通过在模板剂溶液中添加扩孔剂,制备样品的平均孔径可达到29nm.

| Abstract: | In the paper,the template method is adopted,the mesoporous zeolite is prepared under the hydrothermal condition.The synthesised samples are characterized by N2 adsorption-desorption and SEM.There are four factors systematically discussed in the paper,they are types of templates,crystallization temperature,crystallization time,and the addition of enlarge pore agent.The experiment results show that the triblock copolymer(P123) composite with beer yeast as the template agent,the crystallization process is in t... |
