Vincent ORIEZ

Temporary Assistant Professor and Researcher

Supercritical CO2



From 2010 to 2015, I worked in research and development in the industrial sector (Alfa Laval, Novasep, Naturex) on separation processes (continuous chromatography, continuous ion exchange, membrane filtration, electrodialysis, centrifugation, crystallization, atomisation) applied to plant extracts, fermentation broths and microalgae.

During my PhD at the Laboratory of Agro-Industrial Chemistry (LCA) from 2015 to 2019, I studied the chemical fractionation of lignocellulosic biomass (sugarcane bagasse and sunflower oil cake), the characterization of the obtained extracts and their purification by elution chromatography, membrane filtration and precipitation.

Since 2019, I worked in the Chemical Engineering Laboratory (LGC) on an extractive reaction process, and more precisely on the synthesis of hydroxymethyl furfural from fructose in supercritical CO2 – subcritical water two-phase system. It involves kinetic and phase equilibrium studies, experimental and simulation activities
