Problems solved by technology

One of the most critical challenges confronting mankind is that of dwindling sources of non-renewable energy.
The methods and apparatuses of the foregoing two patents, however, involve the heating of the process gases to over 2,000 degrees C., complicating the design, and increasing construction costs, for functional reactor systems.

Embodiment Construction

)

[0024]The present disclosure pertains to an apparatus and method for solar heating gases, such as to heat a feedstock gas to drive an engine, or to heat a gas for processing, for example for methane reformation or to drive a reverse water-gas shift. There is provided by the disclosure a processor by which a feed or process gas, which can be a gas relatively transparent to much of the solar spectrum, can be effectively heated by solar energy so that the hot gas can be harnessed to drive an engine, or for use in the production of useable fuels.

[0025]Succinctly, the presently disclosed apparatus and method allow for collected solar energy to be transferred by convection into a flowing feed or process gas. Convective heating of a flowing gas is, of course, well-known in the art of heat exchangers generally, but the present invention enables the efficient exploitation of solar energy to heat a flowing process gas. Among advantages of the present invention is its capability to provide a ...

Abstract

An apparatus and method for solar energy powered gas processing. There is disclosed a processor assembly for use in heating a process or feed gas by means of a convective heat exchanger which receives solar energy from a focused solar energy collector. A specialized heat exchanger is described, which maximizes the area upon which solar energy can radiate, as well as the available area for heat transfer to the flowing gas. Various modes for operating the processor assembly are described. The apparatus and method may be utilized to heat a gas to drive a heat engine. The apparatus and method also may be used to heat feed gasses to drive a gas processing reaction, such as for steam methane reformation or a reverse water-gas shift reaction.
