Fluidized-Bed Membrane Reactor
Patent 10096/TUB

The fluidized bed membrane reactor can be used in the chemical industry and is suitable for the oxidative coupling of methane and heterogeneous catalysis.

Benefits
  1. Reactor design and membrane dosing avoid thermal afterburning
  2. Fine distribution of oxygen ensures a selective process performance
  3. Fluidized state of the catalyst bed enables a homogeneous and isothermal catalyst area
  4. Easy to scale up for industry requirements
Possible Applications

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

Background

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.

Technical Description

The combined structures of the well-known fluidized bed and a membrane reactor that now are offered; make it possible to 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 39 %, but a selectivity of only 37 % and a yield of just 14.5 %.
