Neneng Purnamawat, Leo Adhar Effendi

Abstract


Oxidation of ferrous sulphate to ferric sulphate was conducted in an agitated reactor using cupri
sulphate as catalyst. This experiment was performed at ferrous sulphate initial concentration of 0.4 N,
reaction temperature of 40-90 C, agitator speed of 220-400 rpm, volumetric rate of gas of 31.94-61.56
mL/s. Mass transfer coefficient and reaction rate constant were calculated by using Runge-Kutta and
Hooke-Jeeves method.
Based on the experimentally result, the value of maximum conversion obtained was 30.71% at
reaction temperature of 70 C, agitator speed of 290 rpm, and volumetric rate of gas of 40.26 mL/s.
Evaluation of mass transfer coefficient and reaction rate constant revealed that the step of controlling the
overall process is chemical reaction.
