使用间歇反应器用673K和0.17g/cm3的超临界水(SCW)处理硬脂酸(C17H35COOH:C17-酸)30分钟。在SCW中，C17酸稳定（转化率为2%），主要产物是CO2和C16烯烃。 SCW反应中添加碱金属氢氧化物(NaOH和KOH)增强了C17酸的脱羧反应，主要产物是CO2和C17烷烃。金属氧化物(CeO2、Y2O3和ZrO2)增强了C17酸的脱羧反应，主要产物是CO2和C16烯烃。根据结果，提出了反应机理。
Stearic acid (C17H35COOH: C17-acid) was treated using a batch reactor with supercritical water (SCW) of 673K and 0.17g/cm3for 30min. In SCW, C17-acid was stable (2% conversion) and the main products were CO2and C16alkene. An addition of alkali hydroxide (NaOH and KOH) in the SCW reaction enhanced the decarboxylation of C17-acid with the main products being CO2and C17alkane. Metal oxides (CeO2, Y2O3and ZrO2) enhanced the decarboxylation of C17-acid and the main products were CO2and C16alkene. Based on the results, the reaction mechanism was proposed.
