Ali Bakhtyari has a Ph.D. in chemical engineering and currently works as a research associate at Shiraz University. His MSc degree was in advanced chemical engineering and the thesis was on adsorptive gas separation. During his Ph.D. career, he published numerous papers and book chapters on different aspects of chemical reaction engineering. The publications cover numerical simulations, catalyst synthesis and characterization, and multifunctional reactors. Simulation, modification, and enhancement of the chemical reactors related to the production of energy carriers such as methanol, dimethyl ether, and hydrogen are of his expertise. Then, his Ph.D. dissertation was on the catalytic hydrotreatment and upgrading of biomass-derived compounds to fuel-grade products and chemicals. Both experimental and theoretical investigations of the conventional and bio-based energy sources are the current and future standpoints of his research career. However, his research activities in the phase equilibria have extended his research area up to biorefinery. Thermodynamic modeling of physical properties and phase equilibria are of his research interests. He has had hitherto contributions in a large number of scientific publications in the aforementioned subjects.
