摘要

以葡萄糖在超临界水气化制氢中的中间产物甲醛为对象

研究了其在超临界水中的气化过程.结果表明:甲醛气化生成的气体产物主要成分是H

、CO

和CO

液体产物主要成分是CH

OH、CH

OCH

和CH

OOCH; 反应温度、压力、时间以及物料含量对反应产物存在影响

其中压力和物料含量对气化过程影响较大; 低压下低温有利于H

生成

高压下高温更有利于H

生成; 反应时间长、甲醛初始含量低亦有利于H

的生成.根据气化后的气、液态产物及其含量

确定了甲醛在超临界水中气化转换的路径.

Abstract

The gasification of formaldehyde

one of main intermediate products in supercritical water gasification of glucose

was investigated under the condition of supercritical water. The results show that during the gasification of formaldehyde the primary components include H

CO and CO

in the gaseous products

and CH

OCH

and CH

OOCH in the liquor products. The products mainly depend on the temperature

pressure

resident time in the reactor

and the solution concentration

especially on the pressure and the solution concentration in the gasification process. According to the products and their contents in gas and liquor

the transferring pathway of formaldehyde in

supercritical water can be identified.
