US Patent:

44433115, Apr 17, 1984

Filed:

Jul 22, 1983

Appl. No.:

6/516066

Inventors:

Norman N. Lichtin - Newton Center MA
Elliot Berman - Los Angeles CA

Assignee:

Atlantic Richfield Company - Los Angeles CA

International Classification:

B01J 1912

US Classification:

204158R

Abstract:

Apr 30, 1996

Appl. No.:

8/640166

Inventors:

Elliot Berman - Quincy MA
Anatoly Grayfer - Newton MA

Assignee:

Zentox Corporation - Ocala FL

International Classification:

B05D 0306
C23C 1648
B01J 1908

US Classification:

427553

Abstract:

A semiconductor catalyst is metalized in situ on a reaction support surface by illuminating at least a portion of the catalyst in the presence of a suitable source of metal to selectively deposit the metal on the illuminated portions. The source of metal can be applied to the reaction support surface either with the catalyst or separately, but is not attached to the catalyst until the structure is illuminated. This causes the metal to be deposited where the catalyst will be illuminated during use and therefore where photopromoted catalytic degradation can occur.

Appl. No.:

5/580032

Inventors:

Elliot Berman - Quincy MA

Assignee:

Exxon Research and Engineering Company - Linden NJ

International Classification:

H05B 3702

US Classification:

315154

Abstract:

An automatic variable lighting device is provided with light responsive means, such as a photocell, for controlling the voltage applied to the lamp in response to ambient light conditions so that a nearly constant contrast between lamp intensity and ambient light intensity results.

Appl. No.:

7/907692

Inventors:

Junchang Dong - Brookline MA
Elliot Berman - Quincy MA

Assignee:

ClearFlow Inc. - Boulder CO

International Classification:

B01J 1912

US Classification:

422186

Abstract:

In a reactor and process for the photopromoted catalytic decomposition of compounds in a fluid stream, the area of a catalyst support structure and/or the amount of catalyst on the support structure is varied as a function of distance from a light source to enhance quantum efficiency. In a preferred embodiment, the support structure has a surface area per unit of reaction chamber volume which increases with distance from the light source, or the amount of catalyst on the support structure per unit area increases with distance from the light source to maintain the light intensity on the catalyst within a desired range regardless of dispersion and/or absorption effects. In another embodiment, the support structure includes a plurality of curved plates which may, for example, be spherical, cylindrical or helical.

Appl. No.:

8/643149

Inventors:

Elliot Berman - Quincy MA
Anatoly Grayfer - Newton MA

Assignee:

Zentox Corporation - Ocala FL

International Classification:

C02F 132

US Classification:

210199

Abstract:

A fibrous matte web is used to support a semiconductor catalyst for use in the photopromoted catalyzed degradation of compounds in a fluid stream. The catalyst, which may be a transition metal oxide, is affixed to at least one side of the matte web, and preferably the downstream side thereof. In one embodiment, the matte web is comprised of a plurality of fibers of glass or other suitable material permitting fluid to pass therethrough, and the side or sides containing the catalyst are directly illuminated by a suitable light source.
