اكسيداسيون كاتاليستي 1- بوتن به انيدريدمالييك در يك راكتور بستر سيال

One of industrial applications of fluidized bed reactors is the production of maleic anhydride on Vanadium Phosphorus Oxide (VPO) catalyst. Synthesis of maleic anhydride from a feed containing 1% v/v of 1-Butene in the air have been investigated in a fluidized bed reactor at various bed temperatures and different gas velocities. The best selectivity and reaction yield obtained when temperature was approximately 395°C and gas velocity was three fold of the minimum velocity for fluidization (U=3Umf). The comparison between experimentally measured selectivity with model predictions showed that the models of K&L and Grace predicted the fluidized bed performance better than others. This is due to the more realistic assumptions of these models indicating the right image of the physical and chemical processes, which happen in the bed.
