研究了在亚临界水条件下，以过氧化氢为氧化剂，在氢氧化钠存在下，部分食物垃圾组分的气化反应。与单独使用氢氧化钠或过氧化氢或不使用氢氧化钠或过氧化氢时相比，同时使用氢氧化钠和过氧化氢时产氢增加。结果表明，过氧化氢对样品有部分氧化作用，而氢氧化钠通过促进水-气变换反应和随后的CO2捕获，显著增加了氢气的产率。在NaOH存在下，主要成分为Na2CO3、CH3COONa和CH3COONa·3H2O。NaOH的存在抑制了焦炭和焦油的生成。
The gasification of some selected components of food wastes using H2O2as the oxidant and in the presence of NaOH has been investigated under subcritical water conditions. Hydrogen production was enhanced when both NaOH and H2O2were used compared to when either NaOH or H2O2alone was used or in their absence. Results indicated that the H2O2acted to partially oxidize the samples while NaOH significantly increased hydrogen gas yields by promoting the water–gas shift reaction with subsequent CO2capture. In the presence of NaOH, the main components were Na2CO3, CH3COONa and CH3COONa·3H2O. Char and tar production were suppressed in the presence of NaOH.
