  • Process for reducing emissions of organic halogen compounds from incineration systems
    Patent number: 5512259
    Abstract: The invention relates to a method for reducing the emission of organic products of incomplete combustion in the off-gases of incineration systems, wherein the off-gas containing the organic products is treated at a temperature from 150.degree. C. to 500.degree. C., under oxidative conditions, with a denox catalyst or a modified denox catalyst. A method is also provided wherein a denox catalyst may be utilized for removing organic products and nitrogen oxides from off-gases.
    Type: Grant

  • Process for decomposing polyhalogenated compounds
    Patent number: 5387734
    Abstract: The invention relates to a process for the decomposition of polyhalogenated aliphatic compounds having 1 to 8 carbon atoms, polyhalogenated cycloalkyl compounds having 5 to 8 carbon atoms and polyhalogenated aromatic compounds having at least 5 carbon atoms. A contaminated substrate or the polychlorinated compounds per se are heated with a suitable catalyst to 150.degree. to 550.degree. C. The process according to the invention is especially suitable for the decomposition of polychlorinated dibenzodioxins and dibenzofurans in soils, scrap loads and waste gases and for decontaminating filter dust from refuse and waste incineration plants.

  • Fungicidally active antibiotic from Streptomyces tendae Ettlinger
    Patent number: 4158608
    Abstract: The new antibiotic Nikkomycin is produced by culturing the strain Streptomyces tendae Ettlinger et al Tu 901 in a nutrient medium at a pH of about 5.5 to 8 under aerobic conditions and isolation by cation exchange from the culture filtrate, followed by elution. The antibiotic is believed to have the structural formula ##STR1## and is characterized by fungicidal activity.
