Biography

Dr. Karhan Özdenkci has had education in chemical engineering field: B. Sc. in Chemical Engineering from Izmir Institute of Technology (a state university in Türkiye), M. Sc. in Process Systems Engineering from Aalto University and Ph. D. in Chemical Technology in Aalto University. He completed his bachelor’s degree as a high honor student with the grade average of 3.59/4.00 and master’s degree with the grade average of 4.27/5.00. He completed his doctoral degree with an award of excellence as well, dissertation involving six highly cited articles.

Dr. Karhan Özdenkci has worked on hydrothermal processes for biomass conversion during his research career: experimental studies, review of operational issues, process simulations, techno-economic assessments and supply chain concepts. His experimental studies include partial wet oxidation and supercritical water gasification. He has conducted techno-economic assessment of integrating supercritical water gasification with a pulp mill. He has also conducted process simulation studies on hydrothermal carbonization of digestate (waste stream of biogas plants). Another important research of him was on a comprehensive analysis of operational issues in hydrothermal liquefaction and supercritical water gasification. His research resulted in a patent of a novel process combining partial wet oxidation, hydrothermal liquefaction and supercritical water gasification as well, addressing the operational issues of each. Regarding circular economy, he has proposed sectoral integration supply chain structure processing 2nd generation and waste biomass.
