以ZrO2-Al2 O3作为催化剂载体,分别制备了SO2-4/ZrO2-Al2 O3、NaOH/ZrO2-Al2 O3、ZrO2-Al2 O33种固体催化剂,并采用酯化后3A分子筛除水和减压反应精馏两种方法精制生物质裂解油。结果表明,在分别使用SO2-4/ZrO2-Al2 O3, NaOH/ZrO2-Al2 O3,ZrO2-Al2 O33种催化剂的条件下,酯化后3A分子筛除水的方式,可以将产品的含水率降至19.6%、18.3%和15.6%,而反应精馏可以将产品含水率分别降低至4.8%、5.4%和3.8%,较之前者效果更加明显。另外,对于3种不同性质的催化剂,结合酯化度计算式,对催化生物油酯化效果进行评价,可知其催化活性为：SO2-4/ZrO2-Al2 O3>NaOH/ZrO2-Al2 O3>ZrO2-Al2 O3。最后,将得到的油品性质进行检测(包括黏度、pH值、密度和热值等),各项结果表明,使用硫酸化催化剂,并采用减压反应精馏的酯化方式可以制备出一种性能优良的液体燃料。

The ZrO2-Al2 O3 was used as a carrier for preparing the catalysts SO2-4 /ZrO2-Al2 O3 , NaOH/ZrO2-Al2 O3 and ZrO2-Al2 O3 in the process of upgrading bio-oil by the methods of dehydration after esterification and reaction recification. Compared these two methods, we could conclude that dehyrating after esterification over 3A molecular sieve could decrease the moisture content to 19. 6%, 18. 3% and 15. 6%, while reaction recification were 4. 8%, 5. 4% and 3. 8% which were better than before under the condition of SO2-4 /ZrO2-Al2 O3 , NaOH/ZrO2-Al2 O3 , ZrO2-Al2 O3 catalyzed, respectively. Meanwhile, according to the evaluation of the bio-oil catalyzed by the modified ZrO2-Al2 O3 with the formula of esterification degree, it indicated the activation of catalysts are SO2-4 /ZrO2-Al2 O3 >NaOH/ZrO2-Al2 O3 >ZrO2-Al2 O3 . Moreover, the quality of the upgraded oil ( kinematics viscosity, pH value, density and heating value ) showed that the bio-oil upgraded by reaction rectification and catalyzed by sulphated metal oxide could produce a out-looking fuel.
