Title: Transport of heat as chemical energy

Do you think this is a good invention? Vote now:

Votes so far: For:(0) Against:(0)
Claims: What I claim as new and desire to secure by Letters Patent of the U.S. is:

1. The process for transporting energy from a source of heat to an energy use area comprising the steps of:

a. reacting a first gas mixture consisting principally of methane and carbon dioxide adjacent said heat source at a temperature in excess of about 650.degree.C to produce a second gas mixture consisting principally of carbon monoxide and hydrogen,

b. cooling said second gas mixture to a temperature below about 40.degree.C,

c. pressurizing and transporting said second gas mixture through a first conduit to said energy use area,

d. heating said second gas mixture,

e. reacting said second gas mixture in the presence of steam and a catalyst at a temperature of at least about 350.degree.C and a pressure of at least about 10 atmospheres to release heat and yield principally methane and carbon dioxide,

f. cooling the resulting mixture containing methane, carbon dioxide and water vapor below the condensation temperature for steam,

g. separating water and by-products formed in step (e) from the mixture containing methane, carbon dioxide and water vapor to produce said first gas mixture,

h. conducting the dried first gas mixture through a second conduit to said heat source,

i. heating said dried first gas mixture and

j. repeating the series of steps set forth above.

2. The process of claim 1 wherein heat released in step (b) is used in step (i) via heat exchange means.

3. The process of claim 1 wherein the first gas mixture is heated to about 925.degree.C.

4. The process of claim 1 wherein the second gas mixture is reacted at a pressure in the 45-100 atmosphere range.

5. The process of claim 1 wherein heat released in step (f) is used in step (d) via heat exchange means.
