A series of fatty acids in microalgae oil, such as stearic acid, palmitic acid, lauric acid, myristic acid, arachidic acid and behenic acid, were selected as the raw materials to produce aviation fuel via hydrothermal decarboxylation over a multi-wall carbon nanotube supported Pt catalyst (Pt/MWCNTs). It was found that Pt/MWCNTs catalysts exhibited higher activity for the hydrothermal decarboxylation of stearic acid with a 97% selectivity toward heptadecane compared to Pt/C and Ru/C under the same conditions. And Pt/MWCNTs is also capable for the decarboxylation of different fatty acids in microalgae oil. The reaction conditions, such as Pt/MWCNTs loading amount, reaction temperature and time were optimized. The activation energy of stearic acid decarboxylation over Pt/MWCNTs was calculated (114 kJ/mol).
微藻油中的一系列脂肪酸，如硬脂酸、棕榈酸、月桂酸、肉豆蔻酸、花生酸和山嵛酸，被选择作为原料，通过多壁碳纳米管负载的 Pt 催化剂（Pt/MWCNTs）的水热脱羧反应来生产航空燃料。研究发现，与 Pt/C 和 Ru/C 相比，Pt/MWCNTs 催化剂在相同条件下对硬脂酸的水热脱羧反应具有更高的活性，对十七烷的选择性达到 97%。此外，Pt/MWCNTs 还能够对微藻油中的不同脂肪酸进行脱羧反应。优化了反应条件，如 Pt/MWCNTs 的负载量、反应温度和时间。计算了 Pt/MWCNTs 上硬脂酸脱羧反应的活化能（114 kJ/mol）。
