The pore size of 3A molecular sieve is 3Ǻ. It does not adsorb any molecular larger than 3 Ǻ. According to the industrial application specialities. We endure our products with the characters of higher adsorption speed, stronger crushing and anticontamination resistance, more cyclic times and longer work-span. All these advantages have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery, polymerization for cracked gases, ethylene, propylene and any other non-acidic gases or liquids in petroleum and chemical industries.Application: Typical applications: 1. Dehydration of many kinds of liquids (say ethanol) 2. Dehydration of air. 3. Dehydration of refrigerant. 4. Dehydration of natural gas or methane. Dehydration of cracked gas, ethylene, ethyne, propylene or butadiene.Typical applications: Dehydration of many kinds of liquids (say ethanol) Dehydration of air. Dehydration of refrigerant. Dehydration of natural gas or methane. Dehydration of cracked gas, ethylene, ethyne, propylene or butadiene.Dose: Molecular sieve is used as a catalyst carrier, the co-adsorption of water and carbon dioxide and co-adsorption of water and hydrogen sulfide gas and is mainly applicable to dry of medicine and air compression systems. Our material will be widely used in Foundry paint & Coating and dry mortar; drying & adsorbent agent; Gas purification of various filed. Hope our new material will be workable for your market.Note: Reactivation Method: Insufflate the sieve bed with vapor to exchange the organics out to avoid char formation at first, and then reactivate the molecular sieve with common method. Attention: To avoid damp and pre-adsorption of organics before running or must to be reactivated.
