Abstract:
A method and system for capturing and isolating carbon dioxide and hydrogen gases from a high temperature synthesis gas stream containing a substantial amount of CO and sulfur compounds for use as a “clean” supplemental fuel, comprising the steps of reducing the temperature of the high temperature synthesis gas stream, removing substantially all of the sulfur compounds present in the synthesis gas, converting a first portion of CO to carbon dioxide in a first high temperature water-gas shift reaction, converting a second portion of CO to carbon dioxide using a second low temperature water-gas shift reaction, converting a third portion of CO to carbon dioxide using a third low temperature water-gas shift reaction and then separating out substantially all hydrogen present in the treated synthesis gas stream.
