  • Process for the hydrothermal treatment of high molar mass biomaterials
    Patent number: 10518245
    Abstract: The present invention concerns a process for the conversion of biomaterials into structural carbon products, particularly utilizing a hydrothermal treatment step that is carried out on a high molar mass organic starting material having a carbon content of >40 wt % of the dry matter. The invention also concerns a structural carbon product obtained using such a process, which has well-defined physico-chemical properties, e.g. in terms of surface area, carbon content, density, size and shape.
    Type: Grant
