P-231 550℃のグルコースの超臨界水ガス化における反応熱の測定(ポスター発表)

It is important to determine the heat of reaction for supercritical water chemical processes engineering, but measurement of heat of reaction in supercritical water has not been conducted. The purpose of this study is to measure the heat of reaction in supercritical water that changes with residence time and reaction temperature. As a model reaction to measure the heat of reaction, glucose was decomposed in supercritical water using a tubular reactor, and inlet and outlet temperatures were measured for the determination of the heat of reaction at 550oC, and compared with the vaules for lower temperatures. It was found that the heat of reaction decreased at 400-450℃, but increased at 450-500℃, and again decreased at 500-550℃ with the reaction temperature increase.
