ABSTRACT:
At a heat source, such as a nuclear reactor, phosgene is reacted to form a mixture of carbon monoxide and chlorine. This mixture of gases is cooled by heat exchange with incoming cold phosgene and is pumped through a first pipeline at ambient temperature to an energy use area. At the energy use end of the first pipeline the gas mixture is heated in the presence of a catalyst, such as activated charcoal. The CO and Cl.sub.2 react exothermically to form COCl.sub.2 (phosgene) with the liberation of 26 keal per mol of phosgene formed. The heat evolved from this reaction is released across a heat exchanger for the boiling of water and superheating of the resultant steam to a temperature in the 400.degree.-500.degree.C range for use as process heat or the generation of electricity. The phosgene produced is cooled and then returned to the heat source end via a second pipeline for repetition of the closed loop process described.
