商业丝光沸石、β 和 ZSM-5 沸石在高压釜中的 HCl 介质中通过常规加热或在 373 K 下微波辐射 15 分钟进行部分脱铝。脱铝程度是沸石结构（β>丝光沸石>ZSM-5）和所用加热方法的函数。对于三种沸石来说，微波比传统加热更快地脱铝。此外，微波的使用影响了所得脱铝样品的表面和酸性特性。 (C) 2011 Elsevier Inc. 保留所有权利。
Commercial mordenite, beta and ZSM-5 zeolites were partially dealuminated in HCl medium in autoclave by conventional heating or under microwave irradiation at 373 K for 15 min. The extent of dealumination was function of the zeolite structure (beta > mordenite > ZSM-5), and the heating method used. Microwaves led to faster dealumination than conventional heating for the three zeolites. Besides, the use of microwaves affected the surface and acidic properties of the resulting dealuminated samples. (C) 2011 Elsevier Inc. All rights reserved.
