This patent describes a process for hydrodewaxing a waxy hydrocarbon feedstock which comprises: (a) contacting the feedstock with hydrogen under hydrodewaxing conditions in the presence of a hydrodewaxing catalyst containing a crystalline composition comprising silicon, oxygen and a Group VIB or Group VIII metal, wherein the crystalline composition contains aluminum boron and gallium in a combined amount less than about 0.75 weight percent and is characterized by an X-ray powder diffraction pattern having a line of at least strong intensity at an interplanar spacing between about 3.8 and 3.9 Angstroms and lines of at least medium intensity at interplanar spacings of 3.75 Angstroms, 3.64 Angstroms, 3.44 Angstroms, 3.30 Angstroms and 3.14 Angstroms; and (b) recovering a product hydrocarbon of reduced pour point.
