Title:
METHOD OF MAKING INDUSTRIAL WHITE OIL
Document Type and Number:
Japanese Patent JPS5355303
Kind Code:
A
Abstract:
A process for making technical white oils in a single step hydrogenation and without the need for acid treating to meet white oil specification by hydrogenating a hydrocracked solvent extracted lubricating oil distilling between 650 DEG and 1050 DEG F., having a SUS/100 DEG F. viscosity of about 200 and an aromatic content of less than about 15% in a single step at 600 DEG to 700 DEG F., and at 2000 to 3000 psig in the presence of a catalyst comprising nickel and tungsten supported on silica-alumina, subjecting the hydrogenated solvent extracted lube oil to atmospheric distillation to remove distillates useful as fuels and subjecting the bottoms of said atmospheric distillation to a vacuum distillation to yield various viscosity grades of technical white oils.
