Abstract: 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.

Abstract: Provided are vessels having at least one tube with at least one aperture formed therein to input fluid, to extract fluid, or both, to or from the interior or exterior of the vessel. Such fluids may contain solid materials. The fluid may be exerted or expelled out of the at least one aperture so as to prevent formation of undesirable or collateral materials, such as ash or slag, or to reduce the formation or accumulation of such materials, or even to reduce or remove any collateral materials otherwise might be created and deposited within the process vessel. Fluid may also be extracted through one or more apertures. In other embodiments, one or more apertured tubes are disposed exterior to the process vessel so as to enable removal of material accumulating on the exterior of the vessel or application of material on the exterior of the vessel.

Abstract: 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.
