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 °C over a Pd/C catalyst in the absence of external H2 . We show that aqueous-phase reforming (APR) of glycerol and subsequent water-gas-shift reaction result in the in situ formation of H2 . While this has a significant positive effect on the deoxygenation activity, the product selectivity towards high-value, long-chain olefins remains high.
报道了一种用于将不饱和甘油三酯和游离脂肪酸转化为直链石蜡和烯烃的一锅法催化水解-脱氧反应。水热脱氧反应在250℃的热压缩水中、在没有外部H2的情况下于Pd/C催化剂上进行。我们表明，甘油的水相重整（APR）和随后的水煤气变换反应导致H2的原位形成。虽然这对脱氧活性有显著的积极影响，但对高价值长链烯烃的产物选择性仍然很高。
