Abstract
A catalytic body contains a base material and, formed on the surface thereof, a catalytic coating layer containing activated alumina, zeolite, a platinum group metal and an inorganic binder. By alternately repeating the step of adsorption of odor components with zeolite and alumina under non-heating condition and the step of heat-regeneration of the zeolite and alumina and catalytic decomposition of odor components under heating condition, offensive odors can be continuously removed over a long period and without excessively raising the temperature in the surroundings of the catalytic body.
