Abstract

Previously proposed methods for the determination of surface hydroxy groups of oxides, based on the reaction of dimethylzinc tetrahydrofuranate with active hydrogen atoms, and for the determination of surface sulfhydryl groups of sulfides, based on the reaction with silver ions, were applied to simultaneous determination of OH and SH groups present on the surface of a sulfided hydrorefining CoMo/Al2O3 catalyst.

Abstract

Ранее предложенные методы определения поверхностных гидроксильных групп окислов, основанные на взаимодействии метилового цинка тетрагидрофураната с активными атомами водорода, и поверхностных сульфгидрильных групп сульфидов, основанные на взаимодействии с ионами серебра, были использованы для одновременного определения групп OH и SH, присутствующих на поверхности сульфидированных катализаторов гидрорафинирования-CoMo/Al2O3.
