  • Patent number: 8801814
    Abstract: A process for partial oxidation of hydrocarbons in a reactor, in which a stream comprising the hydrocarbon and a stream comprising the oxygen are fed to the reactor, wherein both streams fed to the reactor are conducted within the reactor separately through in each case one or more spatially separate lines, these lines having turbulence generators in their interior, owing to which, as a result of the imposed deflection of the flow direction downstream of turbulence generators, a highly turbulent flow field forms, and the streams are then mixed in a mixing zone after exiting from the lines and then converted in a reaction zone.
    Type: Grant

  • Patent number: 8506924
    Abstract: A process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, by first separately preheating the hydrocarbon gas and oxygen gas, and then reacting the gases and cooling the products rapidly. The reactor wall is blanketed with a purge gas stream, introduced through a plurality of feed lines. These feed lines deliver purge gas in a vector direction within a 10° angle of the main flow direction of the reactive gas stream. The purge gas is delivered at multiple stages relative to the main flow direction of the reactive gas stream, and the free cross section of the firing space available to the reactive gas stream, at the height of the feed lines of the purge gas stream, is approximately constant.
