报道了一锅催化水解-脱氧反应，将不饱和甘油三酯和游离脂肪酸转化为直链烷烃和烯烃。水热脱氧反应在250 ° C的热压缩水中在Pd/C催化剂上在不存在外部H-2的情况下进行。我们表明，水相重整（APR）的甘油和随后的水煤气变换反应的结果在原位形成的H-2。虽然这对脱氧活性具有显著的积极影响，但对高价值长链烯烃的产物选择性仍然很高。
A one-pot catalytic hydrolysis-deoxygenation reaction for the conversion of unsaturated triglycerides and free fatty acids to linear paraffins and olefins is reported. The hydrothermal deoxygenation reactions are performed in hot compressed water at 250 degrees C over a Pd/C catalyst in the absence of external H-2. We show that aqueous-phase reforming (APR) of glycerol and subsequent water-gas-shift reaction result in the insitu formation of H-2. While this has a significant positive effect on the deoxygenation activity, the product selectivity towards high-value, long-chain olefins remains high.
