Fluidized-Bed Membrane Reactor


Kurzfassung

With the combined structures of the well-known fluidized bed with the membrane reactor a clear increase in the efficiency of the selective oxidative conversion for higher alkanes can be achieved.


Hintergrund

The conversion of methane into higher hydrocarbons, such as ethane or ethylene, is still a big challenge in the field of catalysis, mainly because the activation of methane is difficult due to its thermo-dynamical stability. Especially the efficiency of oxidative methane coupling is a major problem in currently available systems. Current methods achieve a high selectivity in the conversion of methane, but only a minor yield of higher alkanes, which are the primary goal of the conversion of methane.

Lösung

The combined structures of the well-known fluidized bed reactors and membrane reactor that are offered with thsi invention can achieve a notable increase of the efficiency of the selective oxidative conversion for higher alkanes.

First results

First experiments reached a methane conversion of 39 %, a selectivity of 56 % and a yield of 22 %, in contrast to common techniques with a methane conversion of only 39 %, a selectivity of 37 % and a yield of 14.5 %.


Vorteile

  • Reactor design as well as membrane dosing avoid thermal afterburning
  • Fine distribution of oxygen ensures a selective process performance
  • Fluidized behaviour of the catalyst bed enables a homogeneous and isothermal catalytic area
  • Easy to scale up for industry requirements

Anwendungsbereiche

The fluidized-bed membrane reactor is suitable for oxidative coupling of methane as well as heterogeneous catalysis in general in the chemical industry.
