【摘要】 以多元共组装和湿法浸渍制备两亲性催化剂Pd/C-SiO₂-Al₂O₃,十氢萘和水混合液模拟生物油油水体系,苯酚为模型化合物,研究其加氢脱氧活性.结果表明:相比于亲水性催化剂Pd/C-SiO₂-Al₂O₃和疏水性催化剂Pd/C,两亲性催化剂Pd/C-SiO₂-Al₂O₃具备更高的苯酚转化率和目标产物环己烷的选择性.两亲性催化剂Pd/C-SiO₂-Al₂O₃能稳定油水乳浊液,催化界面反应,在生物油提质中,有很好的应用前景.更多还原

【Abstract】 Amphiphilic catalyst Pd/C-SiO₂-Al₂O₃ has been prepared via a self-assembly process and wet impregnation.In the catalytic reaction,we use decalin and water to simulate oil-water system of bio-oil,phenol as a bio-oil modelcompound.The results show that,Amphiphilic catalysts Pd/C-SiO₂-Al₂O₃ shows higher hydrodeoxygenation activitythan hydrophilic Pd/C-SiO₂-Al₂O₃ and Hydrophobic Pd/C.Amphiphilic catalyst that simultaneously stabilizes water/oilemulsions and catalyze reactions at the liquid/liquid interface would be highly advantageous in biomass upgradingreactions.更多还原
