Abstract��
The V P O system catalystoffluid bed w as studied. The reaction resultis per fect w hen the average particle diam eter of catalyst,used for n butane oxidation tom aleic anhydride,is 75 2��m . The Characteristic of residence tim e distribution w asm easured in fluid bed ofn butane oxidation,the param eters offluid feature w ere es tim ated. The function ofm ass transfer and property ofbackm ix w ere discussed.
