Cu-ZrO2催化材料的制备及其棕榈酸甲酯加氢制脂肪醇性能
Design of Cu-ZrO2 catalyst and its utilization in hydrogenation of methyl palmitate to fatty alcohols
摘要
Abstract
High-carbon alcohols are important chemical raw materials and have extensive applications in the fields of chemistry,chemical engineering,and pharmaceuticals.Converting fatty acids or fatty acid methyl esters from waste oil into high-carbon alcohols through hydrogenation has attracted increasing attention.In this study,a series of Cu-ZrO2 catalysts were prepared by a citric acid-assisted sol-gel method.Results reveal that Cu-ZrO2 catalysts prepared by the sol-gel method mainly exist in the form of tetragonal ZrO2with loaded copper species.There is a certain metal-support interaction between metallic Cu and the ZrO2 support,and ZrO2 crystal phase can be retained during the harsh catalytic reaction conditions.X-ray photoelectron spectroscopy results show that Cu0 species are the key active centers.When the Cu0 content is insufficient,the conversion rate of methyl palmitate increases with the increase of Cu0 content.When the Cu0 content is sufficient,Cu+and Cu0 have a synergistic effect on the hydrogenation reaction.Catalyst dosage,reaction time,reaction temperature and hydrogen pressure were found to have significant effects on the catalytic transformation of methyl palmitate.Increase of reaction temperature can significantly improve the conversion of methyl palmitate.However,excessive temperature can easily induce the dehydration of the generated hexadecanol into by-products such as hexadecane.The conversion of methyl palmitate can be up to 95.1%,and the yield of hexadecanol can reach 91.1%under the conditions of 10%copper loading,300℃,6MPa H2 pressure and 2h reaction.关键词
