For the global energy shortage ethanol is gradually attracting interest taking it as a brand-new fuel. It can be used as an automotive fuel by itself and can be mixed with gasoline to reduce the octane value and improve combustion efficiency, easy up the uptight energy shortage situation. However, in ethanol, there is usually some moisture which will influence the ethanol performance to remove the moisture, we produces a desiccant especially for ethanol water removal to get a high purity ethanol.

3A molecular sieve is specifically designed for drying fuel grade ethanol. Ethanol can only be dried to 95.6% purity by traditional distillation. 3A selectively adsorbs the water from the solution to produce anhydrous ethanol with less than 1% water. This is the drying method of choice for fuel ethanol producers.
