Ru/Co-Al-O负载型催化剂的制备及其加氢脱氧性能研究
Preparation of Ru/Co-Al-O supported catalysts and its hydrodeoxygenation properties
摘要
Abstract
Co-Al layered double hydroxides were prepared by co-precipitation method and converted into composite oxides via calcination.The composite oxide were then used to prepare a series of Ru/Co-Al-O supported catalysts.The structures and properties of the catalysts were characterized by XRD,BET and FT-IR.The hydrodeoxygenation (HDO) properties of these catalysts were tested by using 4-methylphenol as a typical oxygen-containing model compound of lignin biomass oil.This study concentrated on the effects of Co/Al molar ratio and the reduction temperature of the catalyst on the hydrodeoxygenation activity of Ru/Co-Al-O and the optimization of HDO temperature.The results showed that when the molar ratio of Co/Al was 3∶1,the catalyst reduction temperature was 350 ℃ and the reaction temperature was 275 ℃,the HDO activity was the highest:both the conversion and deoxygenation degree in the HDO of p-methyl phenol reached up to 100％.关键词
