Supercritical water gasification of ethanol and butanol in a continuous supercritical water gasification reactor was explored over a range of residence times from 0.7 to 34 s. Residence time was decreased until turbulence was achieved (tau <= 1.2 s). As fluid transitioned from laminar to turbulent flow, the gasification rate was maximized while gasification efficiency was reduced. Gasification rates up to 107 g/L s were observed; this is nearly an order of magnitude higher than previously reported. Arrhenius parameters were estimated to model the intrinsic kinetics of gasification of model compounds in supercritical water without any transport limitations (i.e., turbulence); this technique has never before been applied to supercritical water gasification. The effects of feed, enthalpy of gasification, and residence time on product composition were also explored.
