Ni-Fe系列催化剂用于硬脂酸制备脂肪醇的性能研究
Ni-Fe Catalysts for the Production of Fatty Alcohols From Stearic Acid
摘要
Abstract
The catalytic conversion of stearic acid to fatty alcohols using Ni and Fe metals as active components was studied in the presence of γ-Al2O3,SBA-15,and HZSM-5 supports.Further investigation of the reaction conditions,including temperature,initial H2 pressure,and reaction time,revealed that Ni-Fe/HZSM-5 was not a suitable catalyst for fatty alcohol preparation while Ni-Fe/γ-Al2O3 and Ni-Fe/SBA-15 catalysts exhibited optimal performance at 200 ℃,4 MPa initial H2 pressure,4 h and 190 ℃,3 MPa initial H2 pressure,3 h,respectively.Under these conditions,both catalysts achieved 100％conversion of stearic acid and fatty alcohol selectivities of 98.8％and 99.4％,respectively.The physicochemical properties of the catalysts were analyzed using XRD,BET,H2-TPR,NH3-TPD,and other characterization techniques.The results showed that Ni-Fe/HZSM-5 and Ni-Fe/SBA-15 catalysts formed FeNi3 alloy species,while Ni-Fe/γ-Al2O3 catalysts formed Fe3O4 species.Ni-Fe/HZSM-5 was not conductive to fatty alcohol generation due to its strong acidity.However,due to the low acidity of Ni-Fe/γ-Al2O3 and Ni-Fe/SBA-15,the main product used in the hydrodeoxygenation of stearic acid primarily was fatty alcohols.Among them,the Ni-Fe/SBA-15 catalyst demonstrated superior performance in fatty alcohol production due to its high specific surface area.关键词
