✦ Synopsis

For the oxidative dehydrogenation of methanol to formaldehyde over a Fe-Mo oxide catalyst, the performance of packed-bed membrane reactor (PBMR) was compared experimentally with that of a conventional fixed-bed reactor (FBR) under identical reaction conditions (overall species flowrates, temperature and pressure). Two configurations for PBMR were investigated, using either oxygen (PBMR-O) or methanol (PBMR-M) as permeate with the co-reactant fed directly to the catalytic bed. The influence of reactant residence time, feed concentrations, and temperature was also studied. The kinetics for the reaction network were determined experimentally. Reactor models were then developed for both FBR and PBMRs. These models with no adjustable parameters exhibit good fit with the experimental results.
