3A molecular sieve
Details
Description: 3A molecular sieve is a type of potassium and sodium aluminosilicate crystal aperture Å (0.3nm), molecular adsorption critical diameter is not greater than their own aperture.
Scope of application: oil cracking gas, such as ethylene, propylene,butadiene, acetylene, and the depth of the gas is dry; polar liquids such as ethanol, liquefied petroleum gas, solvent drying.
previous：Sodium silicate (liquid sodium silicate)
next：3A the EPG zeolite
