Molecular sieve manufacturer: dehydration process of molecular sieve

Molecular sieve is a synthetic hydrated aluminosilicate (zeolite) or natural zeolite, which has the function of screening molecules. Due to the different requirements of enterprises, it is sometimes dehydrated. Many users do not understand the dehydration process and the specific operation. Next, the molecular sieve manufacturer will introduce the process and principle.

Zeolite molecular sieves with low silica-alumina ratio (such as A-type, X-type, etc.) and hydrophilicity can be air-dried. In addition, in recent years, the incorporation of ethanol into gasoline to replace part of gasoline has also received extensive attention. The water content of ethanol as a fuel is required to be less than 0.8%, but due to the azeotropy of ethanol and water, only 95% of ethanol can be obtained by rectification. For the dehydration of ethanol with lower water content, zeolite adsorption dehydration is a better choice.

The zeolite used in this method is of type A or X, preferably type KA. On the one hand, it utilizes the grade of type A zeolite. On the other hand, since the pore size of KA zeolite is about 0.3 nm, water molecules can enter freely, and ethanol molecules with a diameter larger than 0.3 nm cannot enter the pores of zeolite. This zeolite dehydration process is an industrial process for producing fuel ethanol.

The above is an introduction to the dehydration process and principle of molecular sieve. According to the introduction, we can understand the use of the product more clearly, so as to better meet the needs of users and meet the effect of use.

The above is the relevant content of the molecular sieve dehydration process and principle introduced by the molecular sieve manufacturer. I hope it can help you. If you need it, you can contact us. We are a professional molecular sieve manufacturer and can provide you with professional help!
