For the purpose of forming hydrogen or hydrogen peroxide from water vapor, or accomplishing other photochemical reactions, a reaction chamber is provided with mercury vapor quartz discharge lamps. In close proximity to the lamps are spheres, or thin continuous wires, or filaments or other physical configurations of laser-type material which produce relatively coherent radiation in a manner similar to lasers. The spheres or filaments include concentric partially reflective surfaces, and include an active material which is pumped by the efficient spectral radiation of the mercury vapor, and radiates at a frequency or frequencies matched to the absorption characteristics of the feedstock being fed through the reaction chamber. The laser-type material may be operated to produce output radiation at a harmonic, such as the second, third, fourth or higher harmonic of the basic laser radiation, and these harmonic output radiations may be enhanced by using semi-reflective coatings which reflect in the order of 70% to 90% of the radiation, particularly in the case of spheres. High energy consent ultraviolet radiation may also be generated by the "beating" of radiant energy from the mercury vapor tubes and the laser-type material. Efficiency is enhanced by chain reactions which occur with the feedstock materials being fed to the reaction chamber; When water vapor and air containing oxygen are fed into the reaction chamber and are irradiated at the appropriate frequency including high ultra violet frequencies, chain reactions occur which involve the generation of activated oxygen atoms. These activated oxygen atoms react with additional water vapor molecules to form hydrogen gas and/or hydrogen peroxide, with an additional activated oxygen atom being available for further reaction. Other compounds, including various organic and chlorine containing compounds may also be efficiently reacted using the present techniques. |
