ABSTRACT:
Processes and apparatus for storing solar energy in synthetic fuels are disclosed. The disclosed processes include the steps of introducing steam and carbonaceous material such as coal, lignite, peat, solid organic wastes, or heavy oils into a molten gasification medium such as one or more molten salts and supplying sufficient solar heat to the gasification medium to maintain it in the molten state at a temperature at which the carbonaceous material and steam react to produce a synthesis gas product including a synthetic fuel gas or gases. Disclosed processes include the step of adding solar absorptivity enhancing dopant material to the gasification medium. Disclosed processes include the step of supplying solar heat to the gasification medium by directing concentrated solar radiation onto the gasification medium, rather than directing the solar radiation onto a separate body of material for indirectly heating the gasification medium. In disclosed apparatus the reactor vessel containing the gasification medium combined with carbonaceous material and steam is located at ground level and concentrated solar rays from a heliostat farm are directed downwardly from a horizontal reflector, through a window, onto the gasification medium.
