Continuous and Precise Metering of Reactants and Solvents into Supercritical Water Gasification Using a Teledyne Isco Syringe Pump and Extractor

Gasification of biomass involves thermal decomposition of organic components in the absence of oxygen. Supercritical water (SCW) is an excellent reaction media to gasify biomass. This note illustrates a compilation of several studies conducted with the supercritical water gasification (SCWG) apparatus. Teledyne Isco 260D syringe pumps are essential parts of the apparatus. They provide precise metering of a variety of high-pressure, ambient temperature fluids into the SCW environment at flow rates sufficient to create turbulent flow of supercritical fluid mixtures at elevated temperatures in the reactors.
