Abstract
Organic hydrocarbon materials are produced from plentiful inorganic limestone type materials by: (1) thermally decomposing the limestone type materials to produce CaO and CO.sub.2, (2) using the CO.sub.2 in a solid electrolyte electrolysis cell to produce CO, (3) catalytically decomposing the CO to produce carbon, (4) reacting the carbon with the CaO produced in step (1), to produce CaC.sub.2, (5) hydrolyzing the CaC.sub.2 toi produce C.sub.2 H.sub.2, (6) catalytically reacting the C.sub.2 H.sub.2 with steam to produce CH.sub.3 COCH.sub.3, (7) pyrolyzing the CH.sub.3 COCH.sub.3 to provide ketene and methane, and separating the ketene. The ketene may then be decomposed to provide methylene, which can be reacted with an alkane, such as methane in an insertion chain reaction, to provide organic hydrocarbon materials. An in-place nuclear reactor can provide energy for the endothermic reactions of the system.
