Systems and Methods for Increasing Carbon Dioxide in Gasification

12) A method for processing a carbonaceous material comprising:

• combining a carbonaceous material and water in a mixing zone to provide a slurried mixture, wherein the water is at least 90% liquid phase;
• gasifying a portion of the slurried mixture in the presence of a combustion gas in a gasification zone to provide carbonaceous solids and a syngas comprising hydrogen, carbon monoxide, and carbon dioxide, wherein the syngas has a temperature of from about 400° C. to about 1,650° C.;
• selectively separating at least a portion of the carbonaceous solids from the syngas in a separation zone to provide a syngas product and carbonaceous solids;
• and
• combusting at least a portion of the carbonaceous solids in the presence of an oxidant in a combustion zone to provide at least a portion of the combustion gas.

19) A system for processing a carbonaceous material comprising:

• a gasification zone adapted to gasify a carbonaceous material and water mixture in the presence of a combustion gas to provide carbonaceous solids and a syngas comprising hydrogen, carbon monoxide, and carbon dioxide, wherein the water is at least 90% liquid phase;
• a separator in fluid communication with the gasification zone adapted to separate at least a portion of the carbonaceous solids from the syngas;
• and
• an oxidation zone in fluid communication with the gasification zone adapted to combust at least a portion of the separated carbonaceous solids to provide at least a portion of the combustion gas.
