| 20120096769 | SOLID FEED SYSTEMS FOR ELEVATED PRESSURE PROCESSES, GASIFICATION SYSTEMS AND RELATED METHODS - A solid feed system may comprise a supersonic nozzle, an isolated injection section having a port for injection of solid feedstock positioned downstream from the supersonic nozzle, and a supersonic diffuser positioned downstream from the isolated injection section. Additionally, a gasification system may comprise such a solid feed system and a reaction chamber downstream thereof. Furthermore, a method of reacting a solid feedstock under pressure may include directing a fluid flow through a supersonic nozzle to provide a supersonic flow stream, and directing the supersonic flow stream through an isolated injection section at a static pressure at least fifty percent (50%) lower than an operating pressure within a reaction chamber (e.g., at a static pressure near ambient pressure). | 04-26-2012 |

| 20130055637 | Systems And Methods For Producing Substitute Natural Gas - Systems and methods for processing a hydrocarbon are provided. The method can include gasifying a feedstock within a gasifier to provide a raw syngas. The raw syngas can be processed within a purification system to provide a treated syngas. A first portion of the treated syngas can be converted into a first effluent in a first methanator. The first effluent can be mixed with a second portion of the treated syngas to provide a first mixed effluent. The first mixed effluent can be converted into a second effluent in a second methanator. The second effluent can be mixed with a third portion of the treated syngas to provide a second mixed effluent. The second mixed effluent can be converted into a third effluent in a third methanator. | 03-07-2013 |

| 20100126069 | GASIFIER FEED SYSTEM - The present invention has been designed to provide a solution to problems with conventional gasifiers which operate by having fuel introduced at one end of a gasification retort and gas and residues removed from the other end. This frequently results in powdered char residues being ejected with the gas, causing increased gas clean-up requirements. The present invention provides a solution to this problem by removing the gas from the retort at the fuel inlet end via the fuel feed apparatus which is preferably a combined ram and scroll feed providing a supply of fuel under anaerobic conditions. | 05-27-2010 |
