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 2 react exothermically to form COCl 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°-500°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.
The process for transporting energy from a source of heat to an energy use area comprising the steps of: a. decomposing phosgene adjacent said heat source at a temperature in excess of about 700°C to produce a gas mixture consisting principally of carbon monoxide and chlorine, b. cooling said gas mixture to a temperature below about 40°C, c. pressurizing and transporting said gas mixture through a first conduit to said energy use area, d. heating said gas mixture, e. reacting said gas mixture in the presence of a catalyst at a temperature of at least about 250°C and a pressure of at least one atmosphere to release heat and yield principally phosgene gas, f. cooling the phosgene gas to a temperature in the range of from about 10°C to about 40°C, g. conducting said phosgene gas through a second conduit to said heat source, h. heating said phosgene gas and i. repeating the series of steps set forth above.
