ABSTRACT:
A process and apparatus for the dehumidification and VOC odor remediation of an air stream withdrawn from the passenger compartment of a transportation vehicle is disclosed which employs a continuously rotating wheel support and adsorbent selective for the adsorption of water and VOCs. The wheel is coated with zeolite adsorbent selected from the group consisting of zeolite Y-74, zeolite Y-84, zeolite Y-85, a low cerium rare earth exchanged zeolite Y-84, a rare earth exchanged zeolite LZ-210 and mixtures thereof. A surprisingly significant increase in the thermal efficiency is possible as a result of the lower regeneration temperature of the adsorbent and the use of novel process steps.
