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