Abstract

An improved process and for removing NOfrom exhaust gases produced by combustion-based energy sources. Catalyst-free exhaust gas is directed into one or more ducts. The gas is cooled and then passes through the duct, wherein the gas flow rate and the electron beam pulse rate are configured to cause each successive volume of gas that flows past the window to be subjected to only a single electron beam pulse in the reaction chamber. A single short, intense electron beam is fired into the exhaust through a window in the reaction chamber as the exhaust flows past the window, with some of the electrons being reflected back into the gas by a reflective plate situated opposite the window. The deposited electron energy causes NOfrom the exhaust to be converted into Nand Owhich are output into the atmosphere with the thus-scrubbed exhaust.
