3a Molecular Sieves For Ethanol Removal

Packing Mall 3A Molecular Sieve for ethanol removal in the liquid phase adsorption experiment, it was observed that each adsorbent had the highest removal water when the ethanol concentration was 90 wt%. With the ethanol concentration decreased to 50 wt% and 15 wt%, the removal water of all adsorbents decreased sharply. At 90 wt% ethanol concentration, the adsorption effect of zeolite 3A was better than that of the immobilized starch and Cellulose Adsorbents. However, at 15 wt% and 50 wt%, the adsorption effect of zeolite 3A on starch and cellulose was better than that of potato starch. However, TiO2 nanowires have better adsorption effect in liquid phase.

Molecular Sieve 3A

Product Description

Isothermal adsorption curves of water vapor and ethanol on molecular sieve 3A for ethanol removal, potato starch, corn starch, cassava starch, cellulose and titanium dioxide nanowires at 24oc. According to the results of gas phase adsorption experiment, when the relative pressure is about 0.6, the ratio of the amount of water adsorbed by the adsorbent to the amount of ethanol adsorbed by potato starch is the highest, with a value of 64.138. The second is cellulose, corn starch, cassava starch, titanium dioxide nanowires, and the last is molecular sieve 3A. From the isothermal adsorption curve, it is found that the non-traditional adsorbent has better selectivity for water and ethanol than molecular sieve 3A.
