Abstract
Invention presents a method of increasing the CO to H2 ratio of syngas. The method comprises passing syngas over a first rector (10) containing Cu at a first temperature effective for the reaction of CO2 within the syngas with the Cu to form copper oxide and CO. The temperature of the syngas is then reduces to a second temperature effective for the for the reaction of hydrogen within the syngas with copper oxide to form Cu and H2O. The syngas is then passed over a second rector (12) containing copper oxide so that the H2 within the syngas reacts with the copper oxide.

A method of increasing the CO to H2 ratio of syngas, the method comprising:
- passing syngas over a first reactor containing Cu at a first temperature effective for the reaction of CO2 within the syngas with the Cu to form copper oxide and CO;
- reducing the temperature of the syngas to a second temperature effective for the reaction of hydrogen within the syngas with copper oxide to form Cu and H2O;
- and
- passing the syngas over a second reactor containing copper oxide so that the H2 within the syngas reacts with the copper oxide.
