Abstract: Organic hydrocarbon materials are produced from plentiful inorganic limestone type materials by: (1) reacting the limestone type materials with molten lithium metal to produce Li.sub.2 C.sub.2 (2) hydrolyzing the Li.sub.2 C.sub.2 to produce C.sub.2 H.sub.2, (3) catalytically reacting the C.sub.2 H.sub.2 with steam to produce CH.sub.3 COCH.sub.3, (4) 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.
