摘    要:使用共沉淀法制备了担载量很高的Ni/Al2O3催化剂,通过正丁醇干燥处理,提高了催化剂的表面积和担载镍的分散度.实验发现,镍的担载量和干燥过程刘催化剂的表面积、孔结构及金属镍的还原度和分散度影响很大.经过正丁醇处理的80%Ni/Al2O3-B催化剂具有较高的表面积,而担载镍的还原度和分散度也显著提高,使得催化剂具有很高...

关 键 词:  氧化铝  正丁醇干燥  活性金属表面积  微量吸附量热  甲苯加氢  苯酚加氢

Abstract:Highly loaded and dispersed Ni/Al2O3-B catalysts were prepared by the co-precipitation method with an n-butanol drying process.The loading of nickel and drying process were found to be the two key factors in determining the surface area and pore structures of catalysts as well as the reducibility and dispersion of supported nickel.The 80%Ni/Al2O3-B treated with n-butanol during the drying process exhibited the high surface area and high reducibility and dispersion of supported nickel,leading to the high act...
Keywords:Ni/Al2O3 catalyst  drying with n-butanol  active metal surface area  microcalorimetric adsorption  hydrogenation of toluene  hydrogenation of phenol
