Simulation of Multitubular Reactor for Oxidative Dehydrogenation of Butene to Butadiene over B02 Catalyst

Du Yingchun; Zhang Jirui(Chemical Engineering Research Center,Beiging institute of Clothing Technology,Beijing 100029)  
he global kinetic model for oxidative dehydrogenation of butene to butadiene over B02 catalyst was obtained by using the data from a industrial and a 250 mL experimental adiabatic reactors;the real industrial adiabatic reactor, isothermal reactor and vanons multitubular reactors with internal heat exchange were simulated by using one--dimensional pseudohomogeneous model.The calculation shows that multitubular fixed bed reactor operated in an autothermic way is superior to the real industrial adiabatic reactor in butadiene selectivity and catalyst life.
