The application of Aspen Plus in the reaction temperature hot spot temperature profile to evaluate the catalyst activity through the impact of catalyst’s deactivation to the reaction performance as well as to correlate the catalytic activity with the industrial phthalic anhydride catalytic reactor conditions, product yield and purity. Subsequently to identify the best operating parameters for maximum phthalic anhydride (PA) yield with desired phthalic anhydride purity in the catalytic reactor. The evaluation showed that higher Mixing Ratio (MR) will result in higher production. However, the yield will drop as the residence time becomes shorter for reaction. As the bottleneck is the hot spot temperature not exceeding 455 oC, the optimum operating condition: Year 1 MR=78g with salt temperature 355.5 oC ; Year 2 MR=95g with salt temperature 360 oC ; Year 3 MR=84g with salt temperature 365 oC.
