Abstract
Disclosed is a method for the purification of exhaust air and/or effluents, which may be exhausted, for example, from auto painting units or furniture lacquering units, involving contacting the air and/or effluents with a molded body. The molded body is made from dealuminated zeolite Y and at least one binder, which may be, for example, bentonites, kaolins, sepiolites or attapulgites, and having a hydrophobic factor of from 1.5 to 6.0, wherein a slurry of the binder in water does not exceed a pH of 10 and wherein the molded body is calcined at 850° to 1100° C. The molded body is produced by a process involving mixing pulverulent dealuminated zeolite Y with at least one binder, optionally with the addition of a lubricant and/or a pore former, and optionally with water or an organic solvent, moulding the resulting mass to form a molded body, and drying and calcining the molded bodies.
