Method for production of carbon dioxide and apparatus therefor
First Claim
1. A method of producing carbon dioxide comprising:
- a) providing a hydride heat engine including desorbing chambers and a hydride compressor;
b) operating said hydride heat engine by directing a hydrogen stream to a heat exchanger wherein the hydrogen is decompressed thereby providing cooling to a cooling vessel, cooling ambient air in a series of counter flow heat exchangers producing a low pressure hydrogen in at least one of the desorbing chambers, returning the low pressure hydrogen to the hydride compressor in a continual process;
c) extracting carbon dioxide from the liquefied ambient air by using the hydride cooling capacity of the desorbing chambers adapted to cool an appropriate separation temperature at which liquid carbon dioxide is separated from the ambient air; and
d) sending the extracted carbon dioxide to a converter unit for collecting the carbon dioxide.

Abstract
A system for conversion of waste and solar heat energy into a carbon sequestration device, including as a collector for collecting carbon dioxide gas from a carbon dioxide gas source, such as ambient air. The Joule Thompson effect is used to cool and thereby refrigerate/liquefy ambient air and then extracting carbon dioxide therefrom, comprising steps of and means for providing a hydride heat engine, operating the hydride heat engine utilizing hydride thermal compression technology to compress hydrogen gas and thereby to cool ambient air to a temperature rendering air into a refrigerated/liquefied state by use of a Joule-Thompson type process, and extracting carbon dioxide from the refrigerated/liquefied ambient air and collecting the carbon dioxide.

5. A method of producing carbon dioxide comprising:
-
a) providing a hydride heat engine including a series of first and second desorbing chambers; b) operating said hydride heat engine through a heat exchange mechanism to compress hydrogen gas in a first chamber of the series of first or second chambers, and decompressing the compressed hydrogen gas in the second chamber of the series of first or second chambers, thereby cooling ambient air adjacent the hydride heat engine to a temperature rendering air into a refrigerated/liquefied state; c) returning the decompressed hydrogen gas to the first of the of the series of first or second chambers to recompress the hydrogen gas in a continual process; d) extracting carbon dioxide from the liquefied ambient air; and e) sending the extracted carbon dioxide to a converter unit for collecting the carbon dioxide. - View Dependent Claims (6, 7)
