Abstract

A wide range of halogen containing reagents (metal halides, oxyhalides, acid halides, etc.) are found to interact from the gas phase with exchange ions of zeolites and to effect dealumination at elevated temperatures. The incorporation of extraneous ions into the framework by this technique is not impossible theoretically. The importance of the method in the preparation of dealuminated and/or metal containing catalysts is discussed.

Abstract

Щыло найдено, что большое число реагентов, содержащих галогены (галогениды металлов, оксигалогениды, кислотные галогениды), взаимодействуют из газовой Фазы с цеолитами, приводя к обмене ионов и вытеснению алюминия. Происходящее при этом внедрение наружных ионов в решетку возможно и теоретически. Обсуждается значение метода в приготовлении катализатора без алюминия и/или катализаторов, содержащих металл.
