    Abstract: What is disclosed is a biorefining process and system including the steps of extracting, hydrolyzing, and/or digesting a lignocellulosic biomass feedstock, or a component thereof, with a liquid or vapor solution comprising reactant sulfur dioxide or a derivative thereof, to generate cellulose-rich solids and an intermediate liquid stream; combusting or gasifying a sulfur-containing fuel to generate heat and an exhaust gas stream comprising produced sulfur dioxide; contacting the exhaust gas stream with the intermediate liquid stream to dissolve the produced sulfur dioxide into the intermediate liquid stream; and then recycling the intermediate liquid stream to reuse the produced sulfur dioxide as the reactant sulfur dioxide. The sulfur- containing fuel may be sulfonated lignin generated by reaction of lignin (derived from the feedstock) with the reactant sulfur dioxide, resulting in a closed loop for sulfur dioxide in the biorefmery.

    Abstract: An oxyfiring system and method for capturing carbon dioxide in a combustion process is disclosed. The oxyfiring system comprises (a) an oxidation reactor for oxidizing a reduced metal oxide; (b) a decomposition reactor wherein oxidized metal oxide sorbents are reduced with oxygen being released and a flue gas with an oxygen enriched carbon dioxide stream is produced; (c) a fuel combustion reactor for combusting a primary fuel and the oxygen enriched carbon dioxide stream into a primary flue gas; and (d) separation apparatus for separating a portion of the primary flue gas so that a carbon dioxide enriched stream can be sent to the decomposition reactor. Steam may be added to assist in controlling the partial pressure of oxygen during decomposition of the metal oxide and a condenser may be used to remove water from the oxygen enriched flue gas.
