Controlled addition of reactants in a fluidized bed membrane reactor
9th International Conference on Circulating Fluidized Beds, CFB 2008, in Conjunction with the 4th International VGB Workshop on Operating Experience with Fluidized Bed Firing Systems (2008)
The focus of this contribution was to evaluate the membrane reactor concept in fluidized beds. The performance of a pilot-plant fluidized bed membrane reactor (FLBMR) was studied experimentally in comparison to the conventional operation as a fluidized bed reactor (FLBR). As model reaction was applied the catalytic oxidative dehydrogenation of ethane using a γ-alumina supported vanadium oxide catalyst. The beneficial effect of oxidant dosing over the membrane is most pronounced at high temperatures and long contact times.
