Abstract:

Ethylene and propylene, two important chemicals in petrochemical industries, are mainly derived from thermal cracking of petroleum or nature gas feedstock. One alternative route for their production is ethanol to olefins process which is a green route. In this research, a complete reaction network was presented for the ethanol to olefins process and thermodynamic analysis of the reactions was carried out to identify the effect of reaction conditions on the process. Thermodynamic analysis which is of great importance can be the first step to realize the reaction network. It should be noted that reactants and the products are considered in their standard states. Calculation of Gibbs free energy change of the reactions is a valid criterion for determining the spontaneity. In the reaction network, 8 groups of overall reactions, being ethanol to olefins, diethyl-ether to light olefins, diethyl-ether reforming, ethanol to acetone, ethanol dehydrogenation, water-gas shift, carbon formation and consumption, methane formation and saturated hydrocarbons formation reactions were considered. Gibbs free energy as a function of temperature was calculated for each reaction group with an emphasis on the expected industrial temperature range 300-500°C. It has been found out that all the reactions can thermodynamically proceed in all temperature ranges. Thermodynamic studies showed that diethyl-ether, acetaldehyde and acetone are some of the byproducts can be involved in the reaction network
