The main objective of this study was to determine the influence of inlet process parameters on performance of synthesis of maleic anhydride from n-butane, in industrial fixed bed reactor. In order to accomplish this objective, a mathematical model is developed. For numerical solution of differential equations, Runge-Kutta-Fehlberg method was used. The most influential inlet process parameters are flow rate of n-butane and flow rate of oxygen. The inlet flow rate of n-butane showed the greatest influence on increasing the conversion of n-butane. Increasing the inlet flow rate of oxygen showed the greatest influence on increasing the yield of maleic anhydride. Decreasing the inlet flow rates of n-butane and oxygen showed the greatest influences on increasing the selectivity of maleic anhydride (their influences are identical). The recommended values for inlet temperature, inlet pressure, inlet flow rate of n-butane and inlet flow rate of oxygen are 431.15 K, 1.38 bar, 27.98 kmol/h and 264.1 kmol/h, respectively.
Key words: process parameters; fixed bed reactor; yield; selectivity.
