  • Process for obtaining benzene, toluene (and naphthalene) from C1-C4-alkanes with co-dosage of hydrogen at a separate location
    Patent number: 8785704
    Abstract: The present invention relates to a process for nonoxidatively dehydroaromatizing a reactant stream comprising C1-C4-aliphatics by converting the reactant stream in the presence of a catalyst in a reaction zone 1 to a product stream P comprising aromatic hydrocarbons, and regenerating the catalyst whose activity has been reduced by deposited coke with a hydrogen-comprising mixture H in a reaction zone 2, wherein at least a portion of the deposited coke is converted to methane and at least a portion of the methane formed is fed to reaction zone 1.
    Type: Grant
    Filed: May 20, 2009
    Date of Patent: July 22, 2014
    Assignee: BASF SE
    Inventors: Frank Kiesslich, Achim Gritsch, Christian Schneider, Albena Kostova
  • Process for producing a catalyst for the oxidation of ethylene to ethylene oxide
    Patent number: 8629079
    Abstract: The invention relates to a process for producing a catalyst for the oxidation of ethylene to ethylene oxide, which comprises a) providing a support which comprises alumina and has been impregnated with silver or with a silver-comprising compound and has a temperature T0; and b) heating the impregnated support from the temperature T0 to a temperature T1 at a heating rate of at least 30 K/min, and also the catalyst itself which can be obtained by this process.
