    小蝌蚪www网在线官网下载提纯的变压吸附法有什么特点？

    小蝌蚪www网在线官网下载提纯的变压吸附法应用十分常见，下面小编给大家普及一下这种方法的特点，希望对大家有所帮助！

    Pressure swing adsorption (PSA) method for biogas purification is very common. Here is a short edition to popularize the characteristics of this method. I hope it will be helpful to everyone!
    变压吸附法（PSA）是在加压条件下，利用小蝌蚪www网在线官网下载中的CH4、CO2以及N2在吸附剂表面被吸附的能力不同而实现分离气体成分的一种方法。组分的吸附量受压力及温度的影响，压力升高时吸附量增加，压力降低时吸附量减少；当温度升高时吸附量减小，温度降低时吸附量增加。变压吸附对气体来源的要求非常严格，H2S的存在会导致吸附剂永久性中毒，并且变压吸附要求气体干燥，所以变压吸附前要先脱除H2S和H2。
    Pressure swing adsorption (PSA) is a method to separate gas components under pressure by using different adsorption capacities of CH4, CO2 and N2 in biogas on the surface of adsorbent. The adsorption capacity of components is affected by pressure and temperature. The adsorption capacity increases with the increase of pressure and decreases with the decrease of pressure. The adsorption capacity decreases with the increase of temperature and increases with the decrease of temperature. Pressure swing adsorption (PSA) requires very strict gas sources. The existence of H2S will lead to permanent poisoning of adsorbents. PSA requires gas drying. So H2S and H2 should be removed before PSA.

    吸附材料在该技术中起到关键的作用，一般采用不同类型的活性炭、沸石、硅胶、氧化铝和分子筛作为吸附材料。不同的吸附材料对小蝌蚪www网在线官网下载的纯化效果各不相同。目前，以活性炭和分子筛为主的碳基吸附剂，在研究小蝌蚪www网在线官网下载提纯方面经常被使用。近年来出现的一些新型吸附材料，如有序介孔材料、胺修饰吸附剂和金属框架物（MOFs）对CO2具有很高吸附选择性，应用前景广阔，而且MOFs被认为是在CO2分离方面具潜力。
    Adsorption materials play a key role in this technology. Generally, different types of activated carbon, zeolite, silica gel, alumina and molecular sieve are used as adsorption materials. Different adsorption materials have different purification effects on biogas. At present, carbon-based adsorbents, mainly activated carbon and molecular sieve, are often used in the study of biogas purification. In recent years, some new adsorbents, such as ordered mesoporous materials, amine modified adsorbents and metal frameworks (MOFs), have high adsorption selectivity for CO2 and have broad application prospects. MOFs are considered to be the most promising adsorbent for CO2 separation.
