摘要
5A分子筛吸附分离混合轻烃中正构烷烃工艺中,需要使用脱附介质对吸附后的分子筛进行脱附,本文分析对比氢气、氮气和水蒸气3种气体作为脱附剂的优缺点。分析认为,三者之间氮气最适合作为脱附介质。
Desorption agent is used for molecular sieve desorption after adsorption during adsorption separation of n-alkanes in mixed light hydrocarbon via5A molecular sieve.This paper describes the advantages and disadvantages of hydrogen,nitrogen and water vapor as desorbent.It concludes that the nitrogen is the optimum medium for desorption.
