Abstract
Abstract A PROCESS FOR PREPARING A BLENDED PETROLEUM OIL FROM A HYDROGENATED PETROLEUM OIL HAVING AN ULTRAVIOLET ABSORPTIVITY OF LESS THAN 0.1 IN THE 330 MILLIMICRON REGION COMPRISES BLENDING FROM 25-95 PARTS BY WEIGHT OF SAID HYDROGENATED PETROLEUM OIL WITH FROM 75-5 PARTS OF AN UNHYDROGENATED PETROLEUM OIL. PREFERABLY, THE HYDROGENATED PETROLEUM OIL HAS A VISCOSITY-GRAVITY CONSTANT (VGC) IN THE RANGE OF 0.78-0.94 AND THE UNHYDROGENATED OIL HAS A VGC IN THE RANGE OF 0.780.899. THE UNHYDROGENATED OIL CAN BE SELECTED FROM RAFFINATE FROM SOLVENT EXTRACTION OF A NAPHTHENIC DISTILLATE, NAPHTHENIC DISTILLATE, NAPHTHENIC ACID-FREE NAPHTHENIC DISTILLATE, DEWAXED PARAFFINIO DISTILLATE, AND MIXTURES THEREOF. THE HYDROGENATED OIL CAN BE HYDROEREFINED PARAFFINIC PETROLEUM OIL, HYDROREFINED NAPHTHENIC PETROLEUM OIL, HYDROCRACKED PETROLEUM OILS, OR MIXTURES THEREOF. THE BLEND CAN CONTAIN, AS AN ADDITIONAL COMPONENT, FROM 0.1-1 WEIGHT PERCENT OF A CATALYTICALLY CRACKED CYCLE OIL.
