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

确定了甲醛在超临界水中气化转换的路径.
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

in the gaseous products
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.
