3A 4A Molecular Sieve
Molecular sieve is a kind of synthetic silicoaluminate with microporous cubic lattice.depending on the size of the pores inside the crystal,the molecules of different substances are adsorbed or repelled,and are therefore called "molecular sieve".substances whose molecular diameter is smaller than the pore diameter of the molecular sieve crystal can enter the molecular sieve crystal and be adsorbed.
The molecular sieve has strong polarity in the crystal cavity,which can have strong interaction with molecules containing polar groups on the zeolite molecular sieve surface,or by inducing polarization of the polarizable molecules to produce strong adsorption.molecular sieve has a strong adsorption capacity for water and carbon dioxide,so in the molecular sieve desulfurization,because the molecular sieve has a strong adsorption capacity for polar small molecules such as water.
