Abstract
Methods and apparatus for purifying gases having organic impurities, including the use of granulated porous glass. The method of the invention includes the following steps. An impure gas comprising a first gas and an organic compound is provided. A packed bed of granulated porous glass is provided. The impure gas is allowed to flow into the packed bed, thereby preferentially adsorbing at least some of the organic compound on the granulated porous glass to yield a purified gas having a concentration of the organic compound that is lower than that of the impure gas. The purified gas is allowed to flow out of the packed bed.
