摘要
介绍了Ni2P催化剂的结构特征、加氢脱氧(HDO)活性相及生物油中典型的含氧化合物,综述了具有代表性的典型含氧化合物呋喃类、酚类、醚类和酯类在Ni2P催化剂催化下的HDO机理方面的最新研究进展。HDO过程中,含氧化合物在催化剂作用下发生C—O键断裂,O主要通过加氢-氢解以H2O的形式脱除,其脱氧产物较为复杂。生物油中富含呋喃类和酚类化合物,因需要苛刻的脱氧反应条件,它们的脱氧难度最大。今后,需进一步深入开展HDO理论研究,探究Ni2P催化剂催化活性的调控机制,制备出性能更加优异的HDO催化剂。
The structure and the active phase for hydrodeoxygenation（HDO）of Ni2 P catalyst and the typical oxygen-containing compounds in bio-oil were introduced.The recent progress in the HDO mechanism over Ni2 P catalysts based on representative oxygen-containing compounds,such as furans,phenols,ethers and esters,was reviewed.During HDO,C—O bonds of oxygen-containing compounds were cleaved under the action of catalysts,and then the oxygen was mainly removed by hydrogenation-hydrogenolysis in the form of H2 O,by which complicated products were produced.Bio-oils were rich in furans and phenolic compounds,and the deoxidization of these compounds needed harsh reaction conditions,therefore,their HDO were of the most challenging.To prepare the catalysts with more excellent HDO performance,the HDO theoretical research and regulatory mechanism for HDO activity of the Ni2 P catalyst were worthy of being further studied.
