Biomass Gasification in Supercritical and Subcritical Water: Kinetic Tests with Different Reactor Materials

D. Castello, A. Kruse & L. Fiori
In this work, experiments concerning supercritical water gasification have been performed. High pressure tests at 300 bar were conducted, operating at temperatures of 350°C and 400°C with different reactor materials namely stainless steel and Inconel® 625. Micro¬autoclaves were used for testing, which allowed great ease of use. Product gas composition, as well as total organic carbon in the produced liquid, were measured at different reaction times. Tests with glucose revealed that, at supercritical conditions, a...
