  • Patent number: 9493407
    Abstract: Disclosed is a method for producing granular urea and reducing ammonia emissions in a gaseous waste stream of the urea granulation process. The method includes the steps of granulating urea and generating a gaseous waste stream from the granulation of the urea, first washing the waste stream in a first scrubber dust stage to remove dust form the gaseous waste stream, and then reacting the gaseous waste stream with formaldehyde in a formaldehyde stage to generate a hexamethylenetetramine and urea-formaldehyde liquid stream, and an ammonia-reduced off-gas stream.

  • Patent number: 6747067
    Abstract: A process for the production of oxygenated C2 hydrocarbons from cellulose is disclosed. The input cellulose waste is gasified using steam in the absence of air and the primary gaseous products of carbon monoxide and hydrogen are subjected to heat, pressure, and catalysts to form methyl alcohol. Carbon monoxide is added to the methyl alcohol and further subjected to heat, pressure and catalysts to form acetic acid. The acetic acid is purified using a distillation tower, and removed for sale. Output production is increased by adding further carbon monoxide and hydrogen from burners used to heat the gasifiers. Further carbon monoxide and hydrogen are also produced by steam gasification of the carbon residue to promote a water/gas shift. These gases are fed into the gas stream produced by the gasification of cellulose, and provide more feedstock for the reactions.

  • Patent number: 5380942
    Abstract: Novel compounds have been discovered that are particularly effective as nucleation accelerators or boosters when employed with hydrazide nucleators in the formulation of silver halide emulsions for lithographic film. The novel compounds contain bis ureido groups joined by an alkyleneoxy moiety or recurring alkyleneoxy moieties. The 2-nitrogen of each ureido group can carry groups comprising hydrogen, aryl, alkyl or dialkylaminoalkyl, alike or different.

  • Patent number: 5274080
    Abstract: Inhibitors of human leukocytes elastase are known to be useful in the treatment of a wide variety of antiinflammatory and antidegenerative diseases. In inhibiting elastase, the therapeutic agents are shown to form a characteristic stable complex with the enzyme. In the radioimmunoassay disclosed herein, the inhibitor-enzyme complex is advantageously hydrolyzed and specific product(s) of the hydrolysis are measured utilizing polyclonal antibodies capable of binding to one or more haptens of formula II ##STR1## wherein M is allyl or n-propyl,Z.sub.1 is(a) 5-benzofuranyl or(b) substituted phenyl wherein the substituent is methyl or ethyloxy.The assays utilizing these antibodies are useful in a clinical setting, for determining appropriate dosage and assessing the effectiveness of treatment.
