低碳醇用于香兰素加氢脱氧催化反应的试验

在一系列Mo2C/AC催化剂上，研究了短链低碳醇作为氢供体在香兰素加氢脱氧催化反应中的作用.实验表明，在香兰素的加氢脱氧催化反应过程中，乙醇不仅作为溶剂，同时也是较理想的氢供体.20% Mo2C/AC催化剂具有最佳的催化性能，在200 ℃温度下，香兰素的转化率达28.2%，4 甲基愈创木酚的选择性高达94.2%，其加氢脱氧活性主要与催化剂中高分散的βMo2C纳米粒子有关.

Short chain alcohol hydrogen donor for the hydrodeoxygenation of vanillin

The short chain alcohols have extensive sources and are easy to store and transport with high safety and mild reaction conditions compared with hydrogen. So it’s a kind of clean and environmental friendly hydrogen donor. The role of short chain alcohols as hydrogen donors for the hydrodeoxygenation(HDO) of vanillin is investigated over a series of different loading of Mo2C/AC catalysts. It is found that ethanol is used as the solvent and the best hydrogen donor at the same time in this process, and 20% Mo2C/AC has showed the best performance among these tested catalysts. The conversion of vanillin and selectivity of 4 methylguaiacol reach 28.2% and 94.2%, respectively, at 200 ℃ for 5 h reaction time. Characterizations indicated that the activity of catalysts for the hydrodeoxygenation of vanillin depends mainly on the highly dispersed β Mo2C nanoparticles of the catalysts.
