Among all of the consumable energy, the liquid fuel is very important. The use of the various technologies to produce this expensive material will be increasing day by day.

Materials & Methods:

The Fischer-Tropsch Process is one of these technologies. In this catalytic process, a lot of products are produced, therefore, it is always steered to the production of favorable products. For this reason, in order to predict the performance of iron-based catalysts, based on the three factors;pressure, temperature and H2/CO ratio, the selectivity models for the products were obtained. Then, the best possible conditions for the highest production of hydrocarbons were calculated which are used in the designing of engineering equipment.

Result & Conclusion:

The optimal condition for the maximum production of total hydrocarbons achieved was set as P=1 MPa, H2/CO=1, and T=542 K.

Keywords: Iron catalyst, Fischer – Tropsch, Selectivity model, Liquid fuel, Optimization, Water gas shift reaction.
