SYNTHESIS GAS PROCESSING AND SYSTEM USING COPPER CATALYST IN TWO STEP REACTIONS AT475-525 .DEGREE. C AND 250-290 .DEGREE. C

摘要

This 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 C02 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 H20. 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.
