P-22 Relationship between Glucose Concentration and Heat of Reaction for its Hydrothermal Decomposition

Abstract

It is important to determine the heat of reaction for subcritical water chemical processes. However, measurement of heat of reaction has not been conducted under hydrothermal condition. The purpose of this study is to measure the heat of chemical reaction under hydrothermal condition with residence time. The reactor is an insulated tubular reactor of stainless steel. Glucose was decomposed in subcritical water, and temperatures on flow are measured so that the heats of reaction along the flow are determined. The reaction is conducted at 350 ℃ and 23 MPa for the glucose concentration of 0.014-0.085 M.
