ABSTRACT:
A device for the recovery of noble metals emanating from the surface of catalysts used in high pressure gas reactions involving absorbing the noble metal dispersed in the reaction gas in an intercepting bed formed of acid-soluble metal oxides in which the external boundary surface of the intercepting bed is 1.5 to 20 times the cross-sectional area of the catalyst surface. The thickness of the intercepting bed, in the direction of gas flow through the material thereof, is 20 to 40 mm., and the flow of the reaction gases in the intercepting bed is in a direction parallel to the plane of the supporting base of the bed.
