US Patent:

46070559, Aug 19, 1986

Filed:

Jul 3, 1985

Appl. No.:

6/751696

Inventors:

Michael V. Grazioso - Poughkeepsie NY
David A. Storm - Montvale NJ

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C07C 2706

US Classification:

518713

Abstract:

A method is provided for preparing a mixture of lower aliphatic alcohols characterized by containing a substantial proportion of aliphatic alcohols having from 2 to 6 carbon atoms by reacting a mixture of carbon monoxide and hydrogen under suitable conditions of temperature and pressure in the presence of a catalyst comprising molybdenum, a metal from the group consisting of cobalt, iron and nickel, and silver, said catalyst being modified by the addition of a promoter from the class consisting of potassium, cesium and rubidium, said promoter being employed at a concentration ranging from about 1. 8 to 13. 0 micromoles of said alkali per square meter of surface area of said catalyst.

Appl. No.:

7/514916

Inventors:

Jerome J. Cuomo - Lincolndale NY

US Classification:

21912143

Abstract:

A process chamber having voltage driven electrodes, e. g. plasma chamber, can be made self cleaning of particle contamination by appropriate design of the workpiece or electrode surface to provide protuberances, grooves or tapers thereon which result in a predetermined pattern in the electrostatic potential within the process chamber which can trap particulate contamination in preselected regions within the plasma chamber. These particles can then be channeled out of the process chamber through a pump port.
