What type of molecular sieve is used for desulfurization of liquefied petroleum gas?
5A molecular sieve: Its pore size is about 5 angstroms, which can effectively adsorb sulfides such as hydrogen sulfide (H₂S). 5A molecular sieve can not only be used to remove hydrogen sulfide from liquefied petroleum gas, but also remove some other impurities such as carbon dioxide (CO₂) and a small amount of water at the same time.
