METHOD AND APPARATUS TO NEUTRALIZE GAS EMISSIONS FROM VAPORS OF ORGANIC COMPOUNDS Russian patent published in 1995 - IPC

FIELD: purification of gasses emissions. SUBSTANCE: gas emissions on stage of adsorption are passed through layer of adsorbent, for example, mordenite, and through layer of adsorbent-catalyst, that has mass of CuO 1.5 5.0, Cr₂O₃ 2.0 7.0, carrier alumosilicate the rest. At stage of regeneration oxygen-containing gas under increased temperature is passed through layers and products of desorption are oxidized during passing through additional layer of adsorbent-catalyst of identical composition. Apparatus to realize method has adsorbers and catalytic reactor. Special feature of the apparatus is that in adsorbers ring-type magazines are set in series according their height. In the case one of magazines is divided for two sections by perforated partition. EFFECT: method and apparatus are used in chemical, petrochemical industries. 2 cl, 3 dwg, 3 tbl
