3A molecular sieves are mainly used to adsorb water and do not adsorb any molecules with a diameter larger than 3A. According to the industrial application characteristics, the molecular sieves we produce have faster adsorption speed, more regeneration times, higher crushing strength and anti-pollution ability, improves the utilization
4A molecular sieve mainly adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, and propylene. It does not adsorb any molecules with a diameter larger than 4A (including propane). Its selective adsorption performance for water is higher than any other molecules. It is one of the most wide
addition to the functions of 3A and 4A molecular sieves, it can also adsorb C3-C4 normal alkanes, ethyl chloride, ethyl bromide, butanol, etc., and can be used for N-isomeric hydrocarbon separation pressure swing adsorption separation, and co-adsorption of water and carbon dioxide.
It is non-toxic, odorless, non-flammable and non-explosive. It has a large surface area and is a high-performance adsorbent. It still has a high adsorption capacity when the adsorbate concentration is very low. It can selectively adsorb, dehydrate and dry, and dewax kerosene.
