B01D 53/62

US Classification:

4232422, 423247

Abstract:

The present invention relates generally to the field of emission control equipment for boilers, heaters, kilns, or other flue gas-, or combustion gas-, generating devices (e.g., those located at power plants, processing plants) and, in particular to a new and useful method and apparatus designed to remove and/or capture carbon oxides (e.g., COor CO) from flue gas-, or combustion gas-, generating devices. In another embodiment, the present invention relates to a method for achieving emission control from flue gas-, or combustion gas-, generating devices where the method achieves a reduction in, or the elimination of, carbon oxides or sulfur oxides contained in the flue gas-, or combustion gas-, generating devices.

Appl. No.:

7/725558

Inventors:

Michael P. May - Canton OH

Assignee:

Molecular Technology Corporation - Canton OH

International Classification:

B01J 800
C01B 2100
B01D 5334

US Classification:

4232391

Abstract:

An improved method is described for reducing the nitrogen oxide content of an effluent gas stream wherein the temperature of the gas varies. The improvement comprises alternately, depending upon the temperature of the gas, contacting the gas with (A) formaldehyde when the gas is at an elevated temperature which is sufficient to promote the reaction of formaldehyde with the nitrogen oxide in the gas and to reduce the nitrogen oxide content in the gas to a desired level, or (B) formaldehyde-derived free radicals capable of reacting with nitrogen oxide when the temperature of the gas is lower than the temperature in (A) and the reaction with formaldehyde does not reduce the nitrogen oxide content to the desired level, whereby the nitrogen oxide content of the gas is reduced to the desired level. The free radicals may be generated by reacting formaldehyde with nitrogen or nitrogen oxide in the presence of a catalyst. Preferred catalysts comprise zirconium, cerium, phosphorus, vanadium, or mixtures thereof.

International Classification:

B01J 800
C01B 1700
B01D 4700

US Classification:

423239

Abstract:

A method is described for converting formaldehyde to a gaseous product mixture capable of reacting with nitrogen oxide which comprises reacting formaldyhyde with nitrogen in the presence of a catalyst which is capable of promoting the reaction between formaldehyde and nitrogen at a temperature below about 1200. degree. F. The gaseous product mixture obtained in this manner is effective in reducing the nitrogen oxide content of combustion gases by mixing the gaseous product mixture with the combustion gas at temperatures from ambient temperature up to about 2000. degree. F.

Molecular Technology Corporation - Canton OH

International Classification:

C01B 2102

US Classification:

4232132

Abstract:

A method is described for promoting a reaction between nitrogen oxide and carbon monoxide which comprises conducting the reaction in the presence of a dysprosium-containing catalyst which is free of noble metals and metals of the first transition series. More particularly, a method is described for reducing the nitrogen oxide and carbon monoxide content of effluent gas streams derived from the combustion of fossil fuels by contacting the effluent gases with a catalyst comprising dysprosium which is free of metals capable of promoting the oxidation of carbon monoxide. Generally, the catalyst is contacted with the effluent gases at temperatures of from about 300. degree. F. to about 1200. degree. F.

Abstract:

A method for concentrating an isotope from an admixture containing the isotope by contacting the admixture with a catalyst capable of selectively catalyzing a reaction with the isotope, and recovering the concentrated isotope from the reaction products. In one embodiment, the method can be used to concentrate deuterium from sources such as hydrogen-rich gas.

International Classification:

C01B 2100
B01J 800

US Classification:

423235

Abstract:

A process is described for reducing the nitrogen content of a post combustion gas which comprises the steps of (A) generating NCO free radicals, and thereafter (B) adding the free radicals to the gas whereby the NCO free radicals react with the nitrogen oxide in the gas to form nitrogen and carbon dioxide. The NCO free radicals may be obtained from a variety of sources such as by the catalytic decomposition of cyanuric acid; the reaction of formaldehyde with nitrogen or nitric oxide; the reaction of carbon monoxide with nitrogen oxide or nitrogen or mixtures thereof; or the reaction of methanol with nitrogen in the presence of a catalyst. The NCO free radicals thus generated are effective for reducing the nitrogen oxide content of combustion gases in accordance with the process of the present invention at temperatures from ambient temperature up to about 2000. degree.
