Abstract

Small quantities of formaldehyde in air are converted into carbon dioxide and water by passage over a catalyst containing copper (II) oxide and/or cobalt (II) oxide. The catalyst may also contain chromic oxide, the weight ratio of Cr to Cu or Co being 0.1-1 to 1. The temperature may be 150-250 DEG C. or lower. The rate of flow of air may be 500-15,000 Nm3 per m3 of catalyst per hour. The catalyst may follow, precede, or be mixed with other catalysts suitable for the oxidation of organic compounds to prevent the formation of formaldehyde.
