Özet:

 

The selective oxidation of benzene to maleic anhydride (MAN)  was studied to compare the performances of fluidized-bed and fixed-bed  reactors.  The gas-phase catalytic oxidation of benzene was carried  out in laboratory-scale fluidized-bed and fixed-bed reactors with a  vanadium pentoxide catalyst supported by silica gel.  The influences  of parameters such as temperature, space time, and air-to-benzene  molar ratio on the reaction selectivity were investigated at normal  atmospheric pressure.  Similar operating conditions were provided in  the experiments carried out in both reactors.  Because of the  limitations of the experimental sets-up and the recommended operating  conditions given in the literature, some differences could be seen  between the reactors.  It was observed that the conversion of benzene  to MAN increased with increasing temperature in both reactors.  It was  further found that both the conversion of benzene to MAN (x1) and the  total conversion of benzene (xT) also increased with increasing  air-to-benzene molar ratios.  This study demonstrates the availability  of the 2 reactors for the oxidation reaction of benzene to MAN.
