  • Langmuir moderate type 1 desiccant mixture for air treatment
    Patent number: 5300138
    Abstract: A desiccant composition having a moderate Langmuir Type 1 moisture adsorption isotherm with a separation factor of from 0.05 to 0.13 is disclosed. The composition contains silica gel, a modified 13.times. molecular sieve (modified by replacing at least 20% of the sodium cations with other metallic cations, e.g., potassium cations), and desirably a hydrophobic adsorbent (desirably a hydrophobic molecular sieve). The composition may be used as the desiccant in a rotary regeneratable dehumidification wheel, thereby significantly enhancing dehumidification performance and simultaneously removing a significant proportion of the airborne pollutants typically contained in indoor and outdoor air.
