A method of converting carbon containing compounds such as coal, methane or other hydrocarbons into a liquid hydrocarbon fuel utilizes a high pressure, high temperature reactor which operates upon a blend of a carbon compound including CO.sub.2 and a carbon source, a catalyst, and steam. Microwave power is directed into the reactor. The catalyst, preferably magnetite, will act as a heating media for the microwave power and the temperature of the reactor will rise to a level to efficiently convert the carbon and steam into hydrogen and carbon monoxide.

A coaxially integrated gasification furnace is described. The coaxially integrated gasification furnace includes a gasification chamber fluidly connected to a gasification cyclone separator. The coaxially integrated gasification system also includes a char combustion chamber fluidly connected to a combustion cyclone separator, in which the char combustion chamber is located within 2024/182640 the gasification chamber. A settling char combustion chamber is located near the char combustion chamber and is separated by a first partition and a second partition from the gasification chamber and the combustion chamber. At least a temperature control element is disposed on the settling isolation chamber.
