一、前言沸石尤其天然沸石历史很久,是1956年瑞典矿物学家克朗斯铁蒂(F,A,F,Cronstedt)发现,因其加热时冒出水蒸汽,所以用希腊语给它起个名字叫“沸腾的石头”(Zeolite),过去曾考虑过用天然沸石作离子交换剂或吸附剂使用,因其纯度低,在利用上受到很大限制。1940年英人白乐(Barrer)首先研究合成沸石,进入50年代后受其影响的伯瑞克[D,Breck(Ucc)]等人终于将合成沸石工业化生产成功。当时Ucc公司的林德事业部(Linde Div)所出售的合成沸石,主要有A型,X型,Y型,L型 I. INTRODUCTION Zeolites, especially natural zeolites, have a long history. They were discovered by the Swedish mineralogist Kronstěti in 1956 (F, A, F, Cronstedt), given its name in Greek Zeolite has been considered in the past to use natural zeolite ion exchangers or adsorbents, because of its low purity, its use is limited. In 1940 Barrer firstly studied the synthesis of zeolites. After entering the 1950s, Berwick [D, Breck (Ucc)] and others finally succeeded in industrialized production of synthetic zeolites. At that time, synthetic zeolites sold by Linde Div of Ucc Company were mainly Type A, Type X, Type Y and Type L
