US Patent:

51205165, Jun 9, 1992

Filed:

Jan 8, 1990

Appl. No.:

7/461923

Inventors:

David O. Ham - Lexington MA
Gary A. Moniz - Windham NH
Melanie J. Gouveia - North Reading MA

Assignee:

Physical Sciences, Inc. - Andover MA

International Classification:

C01B 2100

US Classification:

429235

Abstract:

A method for removing NO. sub. x, particularly nitrogen oxide, emissions from the exhaust products of combustion processes is disclosed. An alkyl amine is added to the stream of exhaust products at relatively low temperatures in the range of 350. degree. -650. degree. C. The alkyl amine does not require a catalyst to react with the nitrogen oxides at these temperatures. Monomethyl amine (CH. sub. 3 NH. sub. 2) is particularly useful.

Appl. No.:

7/434898

Inventors:

Earl J. Taylor - Chelmsford MA
Gary A. Moniz - Windham NH

Assignee:

Physical Sciences Inc. - Andover MA

International Classification:

C25B 100
C25B 1108

US Classification:

204 96

Abstract:

The disclosed electrocatalyst material is useful in electrodes, especially in cathodes for the reduction of oxygen or peroxide to water or hydroxide. The electrocatalyst typically comprises 0. 1 to 20 weight-%, based on the weight of the material, of a supported particulate elemental gold wherein the particles are apparently crystalline in nature, apparently with exposed (100) faces, but smaller in size than 5 nanometers (0. 7 volt vs. RHE at 200 mA/cm. sup.

Appl. No.:

8/449665

Inventors:

Joseph J. Helble - Andover MA
Gary A. Moniz - Windham NH
Theodore F. Morse - Little Compton RI

Assignee:

Physical Sciences, Inc. - Andover MA

International Classification:

B01J 808
B22F 100
B29B 900

US Classification:

422232

Abstract:

An apparatus provides high temperature and short residence time conditions for the production of nanoscale ceramic powders. The apparatus includes a confinement structure having a multiple inclined surfaces for confining flame located between the surfaces so as to define a flame zone. A burner system employs one or more burners to provide flame to the flame zone. Each burner is located in the flame zone in close proximity to at least one of the inclined surfaces. A delivery system disposed adjacent the flame zone delivers an aerosol, comprising an organic or carbonaceous carrier material and a ceramic precursor, to the flame zone to expose the aerosol to a temperature sufficient to induce combustion of the carrier material and vaporization and nucleation, or diffusion and oxidation, of the ceramic precursor to form pure, crystalline, narrow size distribution, nanophase ceramic particles.

Assignee:

Physical Sciences, Inc. - Andover MA

International Classification:

C01B 1334

US Classification:

423592

Abstract:

Submicron sized ceramic particles are produced by combining a ceramic precursor with an organic or carbonaceous carrier material, and exposing droplets of the mixture to a temperature sufficient to cause combustion of the organic material and subsequent vaporization and nucleation, or diffusion and oxidation, of the ceramic precursor to form pure, crystalline, uniform nanophase ceramic particles.
