[Paper]: Hydrothermal fractionation of grape seeds in subcritical water to produce oil extract, sugars and lignin

The fractionation of grape seeds as a model biomass was studied using a combination of two processes: solvothermal extraction using ethanol and hydrothermal fractionation-autohydrolysis process in a semicontinuous reactor using subcritial water. Around 70% of the polyphenols were extracted in the first step and close to 80% of the sugars in the second step.

Optimisation of the direct synthesis of H2O2 in water

Hydrogen peroxide (H2O2) is a green chemical compound widely used because of its strong oxidant properties (Green Chemistry). Some of the hydrogen peroxide applications are related with bleaching process in paper and textile industries, chemical synthesis and waste water treatment. High Pressure Process Group in collaboration with Åbo Akademi from Turku (Finland) have deeply studied […]
