The detected sour odor may be reproduced from a combination of the compounds identified by the analysis method of the present invention. The reproduced sour odor may provide meaningful data required for development of an apparatus and a method for removing specific odors.

  • Patent number: 8652426
    Abstract: The invention relates to the use of aqueous guanidinium formiate solutions, optionally combined with urea and/or ammonia and/or ammonium salts, for the selective catalytic reduction of nitrogen oxides using ammonia in exhaust gases of vehicles. The inventive guanidinium formiate solutions enable a reduction of the nitrogen oxides by approximately 90%. Furthermore, said guanidinium formiate solutions can enable an increase in the ammonia forming potential from 0.2 kg, corresponding to prior art, up to 0.4 kg ammonia per liter of guanidinium formiate, along with freezing resistance (freezing point below ?25° C.). The risk of corrosion of the inventive guanidinium formiate solutions is also significantly reduced compared to that of solutions containing ammonium formiate.

  • Patent number: 8623313
    Abstract: The invention provides a process for efficient synthesis of ammonia. The process includes a water-splitting step in which water is decomposed to obtain a first source gas comprising hydrogen and oxygen, a first oxygen removal step in which the oxygen contained in the first source gas is at least partially separated and removed by an oxygen separating membrane or hydrogen separating membrane to obtain a second source gas having a lower oxygen concentration than the first source gas, a second oxygen removal step in which the oxygen in the second source gas is reacted with hydrogen to produce water for removal, or is adsorbed onto an adsorption medium for removal, to obtain a third source gas having a lower oxygen concentration than the second source gas, and an ammonia synthesis step in which the hydrogen in the third source gas is reacted with nitrogen to synthesize ammonia.

  • Publication number: 20130331622
    Abstract: 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.

  • Patent number: 8603427
    Abstract: A method includes a first step of, with a CO2.H2S stripper maintained to have a pressure higher than atmospheric pressure, from the ammonia-containing wastewater, discharging CO2 and H2S in a form of gas having a low moisture concentration from a tower top of the CO2.H2S stripper while discharging an ammonia-containing solution from a tower bottom of the CO2.H2S stripper; a second step of introducing the ammonia-containing solution obtained after the first step into an ammonia stripper which is maintained to have a lower pressure than that of the CO2.

  • Patent number: 8597583
    Abstract: An ammonia synthesis apparatus includes: a first gas channel; a second gas channel disposed outside the first gas channel; a third gas channel disposed outside the second gas channel; an air supply unit that supplies air to the second or third gas channel; a water supply unit that supplies water to the first gas channel; and a heat supply unit that supplies heat to the first gas channel. A metal or a metal oxide that reduces water to produce hydrogen is placed in the first gas channel. An ammonia synthesis catalyst is placed in the second gas channel located downstream of the downstream end portion of the first gas channel. The second and third gas channels are at least partially partitioned by an oxygen permeation membrane, or a nitrogen permeation membrane, so that oxygen is supplied to the third gas channel, and nitrogen is supplied to the second gas channel.
