Title: NOx reduction by electron beam-produced nitrogen atom injection

Abstract

Deactivated atomic nitrogen generated by an electron beam from a gas stream containing more than 99% N.sub.2 is injected at low temperatures into an engine exhaust to reduce NOx emissions. High NOx reduction efficiency is achieved with compact electron beam devices without use of a catalyst.

Nox reduction system utilizing pulsed hydrocarbon injection

Patent Brusasco, Raymond M [Livermore, CA]; Penetrante, Bernardino M [San Ramon, CA]; Vogtlin, George E [Fremont, CA]; ...

Hydrocarbon co-reductants, such as diesel fuel, are added by pulsed injection to internal combustion engine exhaust to reduce exhaust NO.sub.x to N.sub.2 in the presence of a catalyst. Exhaust NO.sub.x reduction of at least 50% in the emissions is achieved with the addition of less than 5% fuel as a source of the hydrocarbon co-reductants. By means of pulsing the hydrocarbon flow, the amount of pulsed hydrocarbon vapor (itself a pollutant) can be minimized relative to the amount of NO.sub.x species removed.

NOx reduction in combustion with concentrated coal streams and oxygen injection

Patent Kobayashi, Hisashi; Bool, III, Lawrence E.; Snyder, William J.

NOx formation in the combustion of solid hydrocarbonaceous fuel such as coal is reduced by obtaining, from the incoming feed stream of fuel solids and air, a stream having a ratio of fuel solids to air that is higher than that of the feed steam, and injecting the thus obtained stream and a small amount of oxygen to a burner where the fuel solids are combusted.

Method for producing uranium atomic beam source

Patent Krikorian, Oscar H [Danville, CA]

A method for producing a beam of neutral uranium atoms is obtained by vaporizing uranium from a compound UM.sub.x heated to produce U vapor from an M boat or from some other suitable refractory container such as a tungsten boat, where M is a metal whose vapor pressure is negligible compared to that of uranium at the vaporization temperature. The compound, for example, may be the uranium-rhenium compound, URe.sub.2. An evaporation rate in excess of about 10 times that of conventional uranium beam sources is produced.

Low NOx combustion using cogenerated oxygen and nitrogen streams

Patent Kobayashi, Hisashi [Putnam Valley, NY]; Bool, Lawrence E [East Aurora, NY]; Snyder, William J [Ossining, NY]

Combustion of hydrocarbon fuel is achieved with less formation of NOx by feeding the fuel into a slightly oxygen-enriched atmosphere, and separating air into oxygen-rich and nitrogen-rich streams which are fed separately into the combustion device.

Negative ion beam injection apparatus with magnetic shield and electron removal means

Patent Anderson, Oscar A [Berkeley, CA]; Chan, Chun F [Hayward, CA]; Leung, Ka-Ngo [Hercules, CA]

A negative ion source is constructed to produce H.sup.- ions without using Cesium. A high percentage of secondary electrons that typically accompany the extracted H.sup.- are trapped and eliminated from the beam by permanent magnets in the initial stage of acceleration. Penetration of the magnetic field from the permanent magnets into the ion source is minimized. This reduces the destructive effect the magnetic field could have on negative ion production and extraction from the source. A beam expansion section in the extractor results in a strongly converged final beam.
