Application of zeolite molecular sieve

Drying and cleaning applications
(1) dehydration. Air drying can be performed using the polar hydrophilicity of zeolite molecular sieves with low Si / Al ratios (eg, Type A, Type X, etc.). In addition, in recent years, the incorporation of ethanol into gasoline to replace part of gasoline has received widespread attention. As a fuel, ethanol requires less than 0.8% of the water content. However, due to the azeotropic mixture of ethanol and water, only 95% of the ethanol , For the lower water content of ethanol dehydration, zeolite adsorption dehydration is the best choice.
Zeolite molecular sieve used in this method is A or X type, and KA type is the best. On the one hand, the polarity of zeolite type A zeolite is utilized. On the other hand, since the pore diameter of zeolite KA is about 0.3 nm, the water molecules are free Into, and ethanol molecules larger than 0.3nm diameter can not enter the zeolite pore. Chemxin zeolite molecular sieve dehydration process is the preferred industrial production of fuel ethanol process.
(2) purify air pollutants. With the rapid development of industry, the emission of H2S, SO2, NOX and formaldehyde is increasing day by day. The pollution caused has brought serious harm to people’s life and environment.
