Filed:

Oct 27, 2000

Appl. No.:

09/699162

Inventors:

Kevin C. Ott - Los Alamos NM
Noline C. Clark - Jemez Springs NM
Mark T. Paffett - Los Alamos NM

Assignee:

The Regents of the University of California - Los Alamos NM

International Classification:

C01B 2120

US Classification:

4232391, 4232392, 4232132, 4232135

Abstract:

The present invention provides a process for catalytically reducing nitrogen oxides in an exhaust gas stream containing nitrogen oxides and a reductant material by contacting the gas stream under conditions effective to catalytically reduce the nitrogen oxides with a catalyst comprising a aluminum-silicate type material and a minor amount of a metal, the catalyst characterized as having sufficient catalytic activity so as to reduce the nitrogen oxides by at least 60 percent under temperatures within the range of from about 200Â C. to about 400Â C.

International Classification:

C01B037/04

US Classification:

423716, 423305, 423306, 423DIG 30, 502208, 502214

Abstract:

Novel zeolites are produced by combining a polar solute, a silicon or phosphorous source, and a structure directing agent. Surfactants and a hydrophobic solvent are added to the previously mixed three species and shaken to disperse the surfactants. The reverse microemulsion is stirred overnight, at about room temperature and then iced for five to ten minutes. A metal source is added vigorously shaken for about two minutes. The mixture is then aged for about two hours at about room temperature. A mineralizer is added and the resultant mixture aged for about two hours at about room temperature. The mixture is heated to about 180 C. , for a suitable time period. The final novel product is then isolated.

Inventors:

Kevin C. Ott - Los Alamos NM, US

Assignee:

Los Alamos National Security, LLC - Los Alamos NM

International Classification:

B01D 53/56

US Classification:

4232391, 4232392

Abstract:

A Selective Catalytic Reduction (SCR) catalyst was prepared by slurry coating ZSM-5 zeolite onto a cordierite monolith, then subliming an iron salt onto the zeolite, calcining the monolith, and then dipping the monolith either into an aqueous solution of manganese nitrate and cerium nitrate and then calcining, or by similar treatment with separate solutions of manganese nitrate and cerium nitrate. The supported catalyst containing iron, manganese, and cerium showed 80 percent conversion at 113 degrees Celsius of a feed gas containing nitrogen oxides having 4 parts NO to one part NO, about one equivalent ammonia, and excess oxygen; conversion improved to 94 percent at 147 degrees Celsius. NO was not detected (detection limit: 0. 6 percent NO).
