失活5A分子筛再生效果的评价

Appraisal on the Regenerability of Deactivated 5A Molecular Sieves

测定了新鲜和结焦失活及其经空气燃烧除焦再生后的５Ａ分子筛的静态、动态吸附容量、比表面积、差热分析曲线，以评价失活５Ａ分子筛再生效果。试验结果表明，结焦使５Ａ分子筛失去活性。

n this paper,the static and dynamic adsorption capacity,specific surface area and differential thermal analysis curves of 5A molecular sieves including the fresh,cokingdeactivated and decokingregenerated ones,have been measured to appraise the regenerative effects of 5A molecular sieves.The activity of 5A molecular sieves deactivated by coking,can be recovered up to 90 percent by combustion in a stream of air.
