View the Complete Application at the US Patent & Trademark Office
The present invention relates to an improved apparatus and method for conveying fibrous, solid and slurry materials, such as granulated wood, rice hulls, chopped cane and the like, to a pressurized vessel, wherein the material being conveyed is compacted in the feeder in a controlled manner to create a seal at the feeder exit into the pressurized vessel whereby the processing pressure in the vessel is maintained. The invention is particularly useful when used in conjunction with a biomass reactor for the production of gas selectively rich in hydrogen and carbon containing components, such as carbon monoxide, carbon dioxide and methane, which in turn, may be converted into a select end product fuel, such as methanol or ethanol or used as a feed gas for an industrial power plant, such a the biomass reactor for producing gas.
