Zusammenfassung:	Process for the preparation of a lubricating base oil comprising the steps of: (a) contacting a hydrocarbon oil feed in a first stage with hydrogen in the presence of a catalyst comprising at least one Group VIII noble metal component on an refractory oxide support; (b) contacting the liquid effluent in a second stage with hydrogen in the presence of a hydroconversion catalyst under hydroconversion conditions, and (c) recovering at least one lubricating base oil having a viscosity index of at least 80.
