Modeling production of aromatic from n-paraffins with chemical equilibria

Abstract

Chemical Equilibrium models were constructed for modeling and developing the aromatic production model from the normal paraffin at the equilibrium of the reaction with catalysts, i.e. ZSM-5(80) and Mo2C. The models were verified under operating temperatures of 450-500 ° C under atmospheric pressure at 1 atm. By examining the accuracy by comparing the data calculated from each model with the value obtained from the corresponding experiments at the condition that the reaction is balanced. The suitable equilibrium model depends on the type of catalyst used in the system. The accuracy of all equilibrium models could be improved by specifying the desired aromatic yield. In addition, based on the reactor performance, i.e. conversion, and yields, the limitation of the manipulated equilibrium models was evaluated within the operating temperatures and the ratio. Finally, the equilibrium models, could be employed to predict the reactor performance containing other types of catalysts with a variety of temperature and pressure for industrial benefits and reduce operating costs.
