Description and Uses

Used as a desiccant. Y-type molecular sieves have a large specific surface area and a high intracrystalline diffusion rate, and have been widely used in petroleum refining fields such as catalytic cracking, hydrocracking, and isomerization. Molecular sieves combine adsorption and sieving functions: the crystal pores have strong polarity and coulombic field, exhibiting a strong physical adsorption capacity for polar molecules such as water and unsaturated molecules; the pore size distribution is very uniform, allowing only substances with molecular diameters smaller than the pore diameter to enter the crystal pores, thus distinguishing different substances according to adsorption priority and molecular size.
