Hydrothermal gasification

Hydrothermal gasification represents the highest-temperature hydrothermal process, operating at temperatures of up to ~550 °C, producing a gaseous product rich in hydrogen and/or methane. The process is sometimes referred to as supercritical water gasification, since temperatures exceed the critical point for water, and is thus analogous to supercritical water oxidation which operates in the same supercritical region but employs higher temperatures due to the exothermic nature of the oxidation reactions.

Anaerobic digestion optimization through thermal hydrolysis pre-treatment

Pre-treatment of sludge by thermal hydrolysis upstream of anaerobic digestion is used to improve AD efficiency. A study looked at (pre-)commissioning data for a full-scale AD installation undergoing upgrading with TH to assess the basis for optimisation.
