20100129691 | ENHANCED PRODUCT GAS AND POWER EVOLUTION FROM CARBONACEOUS MATERIALS VIA GASIFICATION - Provided are devices and related methods for enhanced gasification of carbonaceous material in which supplemental carbon dioxide is introduced to the gasifier. The gasified carbonaceous material can then be used as a syngas or further processed into hydrocarbon form. The hydrocarbon can then be used in a fuel cell to produce electrical power or used in a traditional combustion process. | 05-27-2010 |
20120311931 | TUNABLE CATALYTIC GASIFIERS AND RELATED METHODS - The present disclosure provides tunable catalytic gasifier systems suitable for gasifying coal, biomass, and other fuel sources. The gasifier reactors of the disclosed systems may be heated by, e.g., a catalytic tube or other jacket that generates heat by catalytically combusting syngas, which syngas may be syngas produced by the gasifier system. | 12-13-2012 |

20090320368 | Methods and Systems for Gasifying a Process Stream - Methods and systems for gasifying process streams are described. In some embodiments, a method for gasifying a process stream includes gasifying the process stream in a first chamber to generate one or more product gases, transporting at least a portion of the one or more product gases to a second chamber, combusting at least a portion of the one or more product gases in the presence of one or more catalysts in the second chamber to generate a heat energy, and indirectly providing the heat energy from the second chamber to the first chamber as a primary heat source to drive gasification of the process stream. | 12-31-2009 |
20110272636 | Method and System for Continuously Pumping a Solid Material and Method and System for Hydrogen Formation - A method of continuously providing a pressurized slurry of a solid material and liquid carbon dioxide is disclosed. The method comprises mixing particles of the solid material and particles of solid carbon dioxide in a mixing container and feeding the mixture of the solid material and the solid carbon dioxide to a pump to form a slurry of the solid material and liquified carbon dioxide. Within the pump, the solid carbon dioxide sublimates, forming a gaseous carbon dioxide which subsequently liquefies due to an increase in pressure. The liquid carbon dioxide and the solid material then mix to form the slurry of the solid material and the liquid carbon dioxide. In some embodiments, the pressurized slurry may be used for pipeline transportation of the solid material. A system of producing a continuous pressurized slurry of solid material and liquid carbon dioxide is also disclosed. A method of producing hydrogen is also disclosed. | 11-10-2011 |

20140249617 | Balloon Expandable Stent Graft and Apparatus and Method for Expanding a Balloon Expandable Stent Graft - A stent-graft delivery system includes a balloon, a sleeve disposed over the balloon, and a stent graft mounted over the sleeve. The sleeve includes a weakened area between a first end and a second end of the sleeve such that when the balloon is expanded, the balloon expands from a center portion of the balloon towards the ends of the balloon. The weakened area of the sleeve may be a slit, a thinner wall section, grooves, notches, or other weakening features. The sleeve may be adhesively attached to an outer shaft of the catheter or to an outer surface of the balloon. | 09-04-2014 |
