Abstract
The present invention relates to the use of expensive and highly selective adsorbents and catalysts for trace contaminant gas removal to generate products of high and ultra-high purity. Mixing such highly selective materials with other less expensive, less selective materials results in the ability to achieve higher purity, higher capacity and/or lower cost without adding additional expensive selective material.
