  • Method for producing spherical activated carbon
    Patent number: 8232226
    Abstract: The invention relates to a method for producing activated carbon, in particular spherical activated carbon, wherein particles are carbonized from an organic precursor substance, wherein the activated carbon obtained from the particles is shock-chilled after carbonization, the temperature gradient being more than 100 K/min.
    Type: Grant
    Filed: August 10, 2006
    Date of Patent: July 31, 2012
    Assignee: Blutcher GmbH
    Inventors: Manfred Schönfeld, Raik Schönfeld
  • METHOD FOR PRODUCING SPHERICAL ACTIVATED CARBON
    Publication number: 20110296990
    Abstract: The invention relates to a method for producing spherical activated carbon, wherein polymer globules, which comprise thermally decomposing chemical groups, are carbonized. It is characterized by that during the carbonization, a supplier of free radicals is added to the polymer globules, the supplier of free radicals forming free radicals, which are different from the free radicals that are generated by the decomposition of the chemical groups.
    Type: Application

  • Spherical active carbon
    Patent number: 7538069
    Abstract: The invention relates to spherical active carbon having the following pore size distribution: a) 1.2 1.7 nm: 20-50%, b) 1.7 2.1 nm: 20-50%, c) 2.1 2.5 nm: 10-25%, d) 2.5 2.9 nm: 3-15%, e) 2.9 3.3 nm: 1-10%. The sum of a) to e) is at least 88%. The difference between the sum of a) to e) in relation to 100% corresponds to a proportion of pores having a diameter of <1,2 nm and/or >3,3 nm. The fractal dimension of the open porosity is at least 2.30.
