Abstract
Odors attributable to organic molecular species are eliminated to levels below their olfactory detection level threshold by contact of the odor-producing species with a crystalline siliceous molecular sieve material having at least about 90 percent of its tetrahedral oxide units as SiO.sub.2 tetrahedra, having pore apertures nominally at least 5.5 A in diameter, from which the original water of hydration has been substantially removed, having a capacity for adsorbed water of not greater than 10 weight percent when measured at 25.degree. C. at a water vapor pressure (p/p.sub.o) of 4.6 torr.
