20110212012 | CARBON-BASED DURABLE GOODS AND RENEWABLE FUEL FROM BIOMASS WASTE DISSOCIATION - Techniques, systems, apparatus and material are disclosed for generating renewable energy from biomass waste while sequestering carbon. In one aspect, a method performed by a reactor to dissociate raw biomass waste into a renewable source energy or a carbon byproduct or both includes receiving the raw biomass waste that includes carbon, hydrogen and oxygen to be dissociated under an anaerobic reaction. Waste heat is recovered from an external heat source to heat the received raw biomass waste. The heated raw biomass waste is dissociated to produce the renewable fuel, carbon byproduct or both. The dissociating includes compacting the heated raw biomass waste, generating heat from an internal heat source, and applying the generated heat to the compacted biomass waste under pressure. | 09-01-2011 |
20130309161 | AMMONIA PRODUCTION BY INTEGRATED INTENSIFIED PROCESSES - An ammonia production process is disclosed. The process uses gasification of biomass waste and the like to produce syngas which, using an integrated system including using nitrogen enriched air and a porous coated catalyst, produces ammonia in a plasma reactor. The ammonia is finally recovered using sulphonated PolyHIPE Polymer which can be used as a fertilizer after neutralisation. | 11-21-2013 |
20140255289 | SYSTEM AND METHOD TO GASIFY AQUEOUS UREA INTO AMMONIA VAPORS USING SECONDARY FLUE GASES - The present invention is a combustion system employing a urea-to-ammonia vapor reactor system. The urea-to-ammonia reactor housing enclosed in a bypass flow duct that receives a secondary flue gas stream at a split point from a main flue gas stream containing nitrogen oxides (NOx) emanating from a boiler. The bypass flow duct allows the secondary flue gas stream to flow past the enclosed reactor housing where injected aqueous urea in atomized or non-atomized form, is gasified to ammonia vapor. The resulting gaseous mixtures of ammonia, its by-products and the secondary flue gas stream subsequently rejoin the main stream, before the main flue gases are treated through a Selective Catalytic Reduction (SCR) reactor apparatus. A residence time of the secondary stream within the bypass flow duct, which may be increased by a recirculation loop, enables effective conversion of urea to ammonia to be used in the SCR apparatus. | 09-11-2014 |
20160074809 | UREA HYDROLYSIS REACTOR FOR SELECTIVE CATALYTIC REDUCTION - This disclosure features a urea conversion catalyst located within a urea decomposition reactor (e.g., a urea decomposition pipe) of a diesel exhaust aftertreatment system. The urea conversion catalyst includes a refractory metal oxide and a cationic dopant. The urea conversion catalyst can decrease the temperature at which urea converts to ammonia, can increase the urea conversion yield, and can decrease the likelihood of incomplete urea conversion. | 03-17-2016 |
