摘　　要：挥发性有机化合物(VOCs)是大气主要污染物之一,分子筛凭借独特的孔道结构、可调变性能好以及稳定性强的特点已被广泛应用于VOCs气体吸附。探究了5A分子筛对乙烷、乙烯气体分子的吸附性能,并分析了吸附温度、循环吸附次数对吸附效果的影响。结果表明:5A分子筛对于小分子VOCs气体吸附性能较好,具有一定的应用前景。Volatile organic compounds(VOCs)are one of the main pollutants in the atmosphere,and zeolites have been widely used in VOCs gas adsorption due to their unique pore structure,good variable performance and strong stability.In this paper,5A zeolite was used to investigate its adsorption properties on ethane and ethylene gas molecules,and the effects of adsorption temperature and cycle adsorption times on the adsorption effect were explored.The results show that 5A zeolite has good performance for small molecule VOCs gas and has a certain application prospect.
