  • Publication number: 20190144351
    Abstract: The present invention relates to a method for producing an organic fertilizer with humic substance properties by oxidizing and ammonifying lignite, wherein the organic fertilizer has a nitrogen content of up to 8 wt. %, based on the dry weight of the fertilizer, and a C/N ratio of 7 to 15, which is characterized in that the method is carried out as a continuous method and comprises the following steps: a) dispersing the lignite and aqueous ammonia solution in a dispersing circuit having a dispersing device, a recirculation container, and a recirculation pump; b) oxidizing the suspension from step a) with an oxygen-containing oxidizing agent at a temperature of <100° C. in an oxidation reactor; c) drying the product suspension obtained in step b) at a temperature of >50° C.; and d) cooling the dried product obtained in step c).

  • Patent number: 8071792
    Abstract: The present invention relates to the technical purification of vinylene carbonate (VC) by means of a simple thermal treatment with organic compounds which possess amidic nitrogen-hydrogen bonds, followed by a distillation and a melt crystallization. In this way VC of ultra-high purity is obtained. The high-purity vinylene carbonate can be stored and transported without stabilizer.

  • Patent number: 7671217
    Abstract: The invention relates to a method for the thermal decarboxylation of dicarboxylic acids, in particular to 3,4-ethylene dioxythiophene-2,5-dicarboxylic acid as an educt. According to said method the educt is used in solid form and/or the reaction is carried out in the presence of a plurality of fluidised bed bodies. No solvents are used in the reaction and the decarboxylation product that is formed during the reaction is carried away from the reaction zone in gaseous form.
