Abstract

Thermodynamic evaluation of syngas production by high-temperature conversion of waste oil was performed using the Gibbs free energy minimization method. Optimum conditions for maximum hydrogen production while minimizing coke formation were determined. Equilibrium calculations were performed at atmospheric pressure with varying fuel excess ratio and water vapor amount. The results show that the optimal conditions for air-steam conversion of waste oil are: fuel excess ratio equal to 3.5 and molar ratio of water vapor to oxygen equal to 0.2. Under these conditions, coke formation does not occur, and hydrogen and carbon monoxide concentrations equal 27.5% and 28.4%, respectively.
