Abstract: A composition for improving the heat reflectivity and the heat resistance of a metal substrate. The coating composition comprises a latex resin including acrylic polymers; silica; and a fire retardant including at least one of a phosphated pentaerythritol ammonium salt, an organo-polyphosphate ammonium salt, an ammonium salt, and a Magnesium salt. The silica reflects and resists heat. Additionally, the silica raises the decomposition temperature of the resin by insulating the resin from heat and reflecting heat away from the resin. This, in turn, increases the ability of the composition to maintain its bond to the substrate at high temperatures. As such, the coating remains on the substrate where it reflects and resists heat, i.e., it does not easily brush or rub off after several hours of exposure to high heat. The silica can be rice hull silica.

Abstract: An activated carbon composition is disclosed, which includes an activated carbon and a carboxylic acid containing compound. The activated carbon composition is prepared by immersing an activated carbon in an aqueous solution of a carboxylic acid containing compound. The activated carbon composition is used for purifying aqueous solutions by providing a bed of the activated carbon composition and passing the aqueous solution through the bed of the activated carbon composition. The aqueous solution is passed through the bed such that the flow of the aqueous solution to be purified into the bed and the flow of purified aqueous solution from the bed has a pH differential less than ±1 pH.

Abstract: The present invention is directed to an activated carbon composition that is resistant to oxidation and the activated carbon bed fires that can result from uncontrolled oxidation of the activated carbon bed. The activated carbon composition of the present invention includes from about 0.0001-25 wt. % of an antioxidant and from about 75-99.9999 wt. % activated carbon including any and all other impregnants and moisture. The presence of the antioxidant on the surface of the activated carbon inhibits uncontrolled oxidation and the activated carbon bed fires that can result. A method of removing solvents from a solvent-laden gas is also disclosed. The method includes passing the solvent-laden gas through an activated carbon bed, which contains the activated carbon composition described above.
