In a catalytic assembly having an oxidation catalytic unit disposed above the broiling area of a fat-food broiler for enabling the catalytic oxidation of volatile broiling smoke organic contaminants, a low pressure drop open-pore metallic flame-arresting filter screen disposed between the broiling area and the catalytic unit and substantially completely overlying the broiling area and containing upon the screen an adherent coating comprising a high surface area inorganic oxide adsorbent and an inorganic binder therefor, the coating serving to adhere salt, phosphorous and other catalyst-poisoning compounds in the broiling emissions. Preferred methods of coating and broiler flame-arresting use are described. |
