随着石油化工工业的发展,国产分子筛已成功地用在大型引进乙烯生产装置中。目前,我国分子筛主要生产厂已有:南京无机化工厂、中美上海环球联碳分子筛有限公司、大连催化剂厂、湘潭第二化工厂等。为满足对分子筛产品质量的要求,我国于80年代初就开展了分子筛标准化工作,在开始时的一段时间内,主要做了基础性工作,制订了4项试验方法标准,以便为制订分子筛产品标准打下基础,这4项试验方法标准是:GB6286—86《分子筛堆积密度测定方法》,GB6287—86《分子筛静态水吸附测定方法》;GB6288—86《粒状分子筛粒度测定方法》;GB8770—88《分子筛动态水吸附测定方法》。这4项试验方法,是测定分子筛基本参 With the development of the petrochemical industry, domestic molecular sieve has been successfully used in the large-scale introduction of ethylene production plant. At present, China’s major molecular sieve production plants have been: Nanjing inorganic chemical plant, Sino-US Shanghai World Carbon Molecular Sieve Co., Ltd., Dalian catalyst plant, the second Xiangtan Chemical Plant. In order to meet the requirements of molecular sieve product quality, we carried out the molecular sieve standardization work in the early 1980s. During the initial period of time, we mainly did basic work and formulated four test method standards in order to set the standard of molecular sieve product Lay the foundation, the four test method standards are: GB6286-86 “molecular sieve bulk density determination method”, GB6287-86 “molecular sieve static water adsorption determination method”; GB6288-86 “granular zeolite particle size determination method”; GB8770-88 “molecular sieve Dynamic water adsorption assay. ” These four test methods, is the determination of molecular sieve basic parameters
