The light alcohol component of exhaust gases from such commercial operations as paint spraying booths and printing presses is found to be selectively adsorbed, even under high relative humidity conditions, to a surprisingly high degree using bonded high-silica zeolite agglomerates which have been calcined only once to remove the organic templating agent present in the as-synthesized form of the zeolite. Under certain conditions of alcohol concentration and relative humidity, the capacity of the once-calcined zeolite for alcohol adsorption is nearly twice as great as the same zeolite which has been calcined more than once at temperatures high enough to decompose and remove the organic moieties.
