This paper aims at illustrating a case of scaling-up an industrial process-the oxidativedehydrogenation of butene. According to the preliminary experiments, attention has beenpaid to the considerable difference between laboratory and commercial scale reactors. Variousfactors which make multiplicity prossible are studied using mathelnatical modeling and com-puter simulation. It has been explained why multiplicity disappears in a commercial scale reac-tor. Both computer simulation and experimental results have revealed that the inlet gas tem-perature and gas velocity are sensitive factors.The authors have noticed various effects of theheat feedback through reactor wall in two reactors of different diameters and the effect ofgas velocity. Finally,a commercial scale reactor is successfully developed.
