Summary

By selectively taking advantage of the best features of the natural material, a new class of natural adsorbents with a higher affinity for water was then synthesized using materials derived from corn: starch and cob flour. This material gave reasonable and reproducible results, similar to those obtained with molecular sieves using a commercially available pressure-swing air dryer. After 70 hours of operation at 210 kilopascals, the new adsorbent provided air at a dewpoint of -63 deg C. The methods for preparing this material and an explanation of its performance in terms of macroscopic and microscopic structural characteristics are described.
