A synthetic ember comprising refractory ceramic wool coated with about 0.10 wt. % to about 5.0 wt. % of an oxidation catalyst of Pt, Pd, Rh, Co, Mn and mixtures thereof for use in small pieces as embers in a gas-fired log set or fireplace. The refractory ceramic wool preferably has a surface area of from 20 to 200 square meters per gram and a density of 0.01 to 0.05 grams per cubic centimeter and the catalytic embers are less than one inch square. The synthetic embers increase heat recoverable at a given BTU from a flame, with reduced nitrogen oxides, hydrocarbons and CO emissions and improved aesthetics.

Catalytic embers for use with a gas fired log set

A device for improving the efficiency, safety and cleanliness of cooking on a grill wherein the device is placed between the item being cooked and the heat source. Said device being a chamber with dimensions proportional to those of the cooking surface. The chamber is encased by a top surface and a bottom surface. The bottom surface is to be compatible with and coated by an oxidation catalyst, constructed by one or more layers, have structural integrity and constructed so that gases can pass freely through the structure while any liquids or solids falling from above would be interrupted by impingement. The top surface is to be compatible with and coated by an oxidation catalyst and having a structure constructed of one or more layers which would allow substantial flow of liquids and gases. The top and bottom surface forming a chamber with dimensions of separation ranging from 0.1 inches to 6 inches. The top layer to be optimized for collecting and oxidizing the fats and oils to reduce flame but not smoke. The bottom layer to have a higher level of activity in order to more completely destroy any fats or oils which might penetrate the top layer.
