酚类加氢脱氧反应合成烃类是生物油精制合成高品位液体动力燃料的主要控制步骤，生物油酚类化合物加氢脱氧催化剂是研发关键。Ni基复合介孔催化剂在生物油精制反应中具有优异的催化性能，是生物油精制催化剂研究的热点。本项目围绕Ni/Al-SBA-15中Ni物种的分散调控机制和Ni/Al-SBA-15催化生物油酚类化合物加氢脱氧性能研究为目标，从Ni物种与载体Al-SBA-15的相互作用出发，采用不同实验手段调控载体表面的羟基和酸密度，改变Ni/Al-SBA-15制备方法，探究Ni物种的分散度与载体表面羟基密度、酸密度变化之间的关系。结合理论分析与模拟计算，阐明Ni物种在Al-SBA-15载体上的分散调控机制；通过对比不同Ni分散度的Ni/Al-SBA-15催化酚类加氢脱氧性能，揭示Ni物种分散度与催化酚类化合物加氢脱氧性能的关联规律。为开发具有高活性、高稳定性的Ni基生物油加氢脱氧催化剂奠定理论基础。

Upgrading bio-oil by hydrodeoxygenation (HDO) to produce high-quality transportation fuel has been widely accepted is an environmentally-friendly and sustainable rout to overcome the pollution problem by reducing carbon emission. More importantly, design and preparation of efficient catalyst plays the critical role in the aforementioned process. Nickel-based catalyst that consisting a certain amount of mesostructure showed great catalytic performance in bio-oil upgrading reactions, and therefore has been regarded as the competitive candidates. This project will focus on the preparation of Ni/Al-SBA-15 and investigating the catalytic performance in HDO of phenolic compounds. The main task in this project are including as follows:.（1）Investigate the interaction between the nickel species and hydroxyl group on Al-SBA-15;.（2）Understand the forming mechanism of highly-dispersed Ni species on the support;.（3）Study the effect of support acidic property on the nickel dispersion;.（4）Study the catalytic performance of Ni/Al-SBA-15 over HDO reaction..We hope that the implementation of this project might provide new idea and accumulate technological methods for the preparation of highly active and stable HDO catalyst.
