Abstract
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.
Claims5
A flame arresting and fume absorbing system for the catalytic oxidation of organic contaminants and the adsorption of inorganic contaminants generated from the broiling area of a fat food broiler, comprising an oxidation catalytic unit, a filter screen and a coating for said filter screen wherein the filter screen exhibits low pressure drop, wherein the filter screen is open-pored and metallic, wherein said filter screen is located between the broiling area of the fat food broiler and the catalytic unit, and wherein said coating comprises a high surface area inorganic adsorbent secured to the filter screen by an inorganic binder, whereby salt, phosphorous and other catalyst-damaging compounds are adsorbed by the inorganic adsorbent.
