In the present study, hydrogen production process from ethanol was developed with the aid of Aspen Plus. Firstly, the effect of reactor types on ethanol conversion rates was investigated by simulating three different reactors in Aspen Plus and it was determined that the RGibss reactor provided the best conversion rate compare to REquilibrium and RPlug. Two different activity coefficient models, UNIFAC and UNIQUAC, have been tested and the best conversion rate has attained with the use UNIQUAC model. Once the optimal best reactor type and activity coefficient model were decided, the effects of reactor operating parameters such as temperature, pressure and mixing ratio on ethanol conversion rate were studied respectively. Temperature, pressure and mixing ratio for the optimal conversion rate of ethanol were determined as 500 °C, 1 atm and 1/4 respectively. Finally, a separator was used to purify the hydrogen gas and pure H2 with a purity of 99.9% was subsequently produced. The obtained data indicate that Aspen Plus simulator has been performed successfully and shows that such successful simulations can minimize experimental costs and time loss.
