Abstract

This review article highlights the importance of mesoporous material MCM-41 in the hydrodeoxygenation (HDO) of bio-oils, a crucial process for converting biomass into high-quality biofuels. Bio-oil, derived from the fast pyrolysis of biomass, contains a high concentration of oxygenated compounds that compromise its stability and miscibility with fossil fuels. HDO selectively removes this oxygen, enhancing its properties and enabling its energetic application. This study explores the influence of MCM-41-supported catalysts on process efficiency, attributed to their high surface area and thermal stability. Incorporating metals such as Ni, Co, Mo, and Pd improves HDO selectivity, promoting essential reactions for converting oxygenated compounds. Furthermore, the article emphasizes the necessity of bifunctional catalysts to minimize coke formation and enhance the industrial feasibility of the process, providing valuable guidelines for future research aimed at optimizing HDO.

mcm -41负载金属对生物油加氢脱氧研究进展

本文综述了介孔材料MCM-41在生物油加氢脱氧（HDO）中的重要性，这是将生物质转化为高质量生物燃料的关键过程。生物油来源于生物质的快速热解，含有高浓度的含氧化合物，会影响其稳定性和与化石燃料的混溶性。HDO选择性地去除这种氧，增强其性能并使其具有高能应用。本研究探讨了mcm -41负载催化剂对工艺效率的影响，归因于其高表面积和热稳定性。加入金属如Ni、Co、Mo和Pd提高了HDO的选择性，促进了转化含氧化合物的基本反应。此外，文章还强调了双功能催化剂的必要性，以减少焦炭的形成，提高该工艺的工业可行性，为未来优化HDO的研究提供了有价值的指导。
