summary:
The pore size of 4A molecular sieve is 4A, capable of adsorbing water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, and propylene Any molecule with an adsorption diameter greater than 4A (including propane) has higher selective adsorption performance for water than any other molecule. It is one of the most widely used molecular sieve varieties in industry.
