超临界水中葡萄糖气化制氢实验研究

Experimental study of hydrogen production from glucose gasification in supercritical water

以葡萄糖为生物质模型化合物,在超临界水中进行气化反应,考察不同压力、温度、物料浓度等对气化产物组成及气化制氢效果的影响。实验结果表明,反应器壁温在500—650℃范围内,温度的升高有利于葡萄糖的气化制氢,25MPa、650℃时气化率超过100%。添加适当的催化剂可以有效促进水气转化反应。

As a model compound of biomass, glucose was gasified in supercritical water. The effects of different pressure, temperature, concentration of the solution and catalyst on the gas production and the efficiency of glucose gasification were experimentally studied. The result shows when the temperature increased from 500 ℃ to 650 ℃, the hydrogen yield of glucose gasification increased. At 25 MPa and 650 ℃, the efficiency of gasification is more than 100%. In addition, the appropriate catalyst can effectively promote the water-gas shift reaction.
