摘要: A method for processing brewery waste that includes receiving spent grain, low strength wastewater and high strength wastewater. The spent grain, low strength wastewater and high strength wastewater is processed with a plug flow anaerobic digester to produce a first output. A portion of the first output is processed with an upflow anaerobic sludge blanket digester to produce a second output. A portion of the second output is processed with a fixed-film anaerobic digester to produce a third output.

摘要: 2,4,6,2',4',6'-Hexanitro-3,5,3',5'-tetrachloroazobenzene, a new, high melting explosive is prepared by the simultaneous nitration and oxidation of 3,5-dichloroaniline in strong or fuming sulfuric acid using fuming nitric acid or potassium nitrate as both oxidizing and nitrating agent. Under these conditions nitric acid or potassium nitrate is expected to be a nitrating agent only, and oxidation of the amino group is not expected.

摘要: An anaerobic digester is disclosed including a single orbicular vessel having two chambers configured for the separate treatment of high-solids and low-solids phases of organic matter. The vessel combines a high solids, plug flow path wherein low solids liquids are separated and directed to a high rate treatment path. The invention provides a novel and simple apparatus for the anaerobic conversion of both high solid and low solid wastes to methane, carbon dioxide, a liquid effluent that can be used as fertilizer, and a solid residue that can be used as a soil amendment. The invention combines the advantages of high solids loop digesters and low solids high rate digesters into a single orbicular vessel. Due to the orbicular geometry, in which a first chamber is a path surrounding and orbiting a second chamber, the apparatus has greater thermal and material efficiencies.
