Abstract

Molybdenum oxide-modified ruthenium on titanium oxide (Ru-()MoO /TiO; is the loading amount of Mo) catalysts show high activity for the hydroconversion of carboxylic acids to the corresponding alcohols (fatty alcohols) and aliphatic alkanes (biofuels) in 2-propanol/water (4.0/1.0 v/v) solvent in a batch reactor under mild reaction conditions. Among the Ru-()MoO /TiO catalysts tested, the Ru-(0.026)MoO /TiO (Mo loading amount of 0.026 mmol g) catalyst shows the highest yield of aliphatic -alkanes from hydroconversion of coconut oil derived lauric acid and various aliphatic fatty acid C6-C18 precursors at 170-230 °C, 30-40 bar for 7-20 h. Over Ru-(0.026)MoO /TiO, as the best catalyst, the hydroconversion of lauric acid at lower reaction temperatures (130 ≥ ≤ 150 °C) produced dodecane-1-ol and dodecyl dodecanoate as the result of further esterification of lauric acid and the corresponding alcohols. An increase in reaction temperature up to 230 °C significantly enhanced the degree of hydrodeoxygenation of lauric acid and produced -dodecane with maximum yield (up to 80%) at 230 °C, H 40 bar for 7 h. Notably, the reusability of the Ru-(0.026)MoO /TiO catalyst is slightly limited by the aggregation of Ru nanoparticles and the collapse of the catalyst structure.

摘要

氧化钼改性的负载在二氧化钛上的钌（Ru-(x)MoO₃/TiO₂；x为Mo的负载量）催化剂，在间歇式反应器中，于温和反应条件下，在2-丙醇/水（4.0/1.0 v/v）溶剂中，对羧酸加氢转化为相应的醇（脂肪醇）和脂肪族烷烃（生物燃料）表现出高活性。在所测试的Ru-(x)MoO₃/TiO₂催化剂中，Ru-(0.026)MoO₃/TiO₂（Mo负载量为0.026 mmol/g）催化剂在170 - 230℃、30 - 40 bar下反应7 - 20 h时，由椰子油衍生的月桂酸和各种C6 - C18脂肪族脂肪酸前体加氢转化生成脂肪族烷烃的产率最高。在Ru-(0.026)MoO₃/TiO₂（作为最佳催化剂）上，较低反应温度（130≤T≤150℃）下月桂酸的加氢转化产生了十二烷-1-醇和十二烷酸十二酯，这是月桂酸与相应醇进一步酯化的结果。反应温度升高至230℃显著提高了月桂酸的加氢脱氧程度，并在230℃、H₂ 40 bar下反应7 h时产生了最高产率（高达80%）的正十二烷。值得注意的是，Ru-(0.026)MoO₃/TiO₂催化剂的可重复使用性受到Ru纳米颗粒聚集和催化剂结构坍塌的轻微限制。
