    摘要: A base oil slate comprising three or more base oil grades having kinematic viscosities at 100° C. between about 1.8 cSt and about 30 cSt prepared from a waxy feed wherein each of the base oil grades is a base oil blend which comprises: (a) between about 0.1 wt. % and about 99.9 wt. % of a distillation fraction prepared in light block mode operation; and (b) between about 0.1 wt. % and about 99.9 wt. % of a distillation fraction prepared in medium block mode operation. Also, a base oil slate prepared from a waxy feed, said product slate comprising 3 or more base oil grades, each base oil grade having a kinematic viscosity at 100° C. between about 1.8 cSt and about 30 cSt and a VI greater than an amount defined by the equation VI=Ln(Vis100, in cSt)+95, wherein Ln(Vis100, in cSt) is the natural log of the kinematic viscosity at 100° C.

    摘要: A method for predicting properties of lubricant base oil blends, comprising the steps of generating an NMR spectrum, HPLC-UV spectrum, and FIMS spectrum of a sample of a blend of at least two lubricant base oils and determining at least one composite structural molecular parameter of the sample from said spectrums. SIMDIST and HPO analyses of the sample are then generated in order to determine a composite boiling point distribution and molecular weight of the sample from such analysis. A composite structural molecular parameter is applied, and the composite boiling point distribution and the composite molecular weight to a trained neural network is trained to correlate with the composite structural molecular parameter composite boiling point distribution and the composite molecular weight so as to predict composite properties of the sample. The properties comprise Kinematic Viscosity at 40 C, Kinematic Viscosity at 100 C, Viscosity Index, Cloud Point, and Oxidation Performance.

    摘要: A process for producing a product slate, which includes at least three base oil grades having kinematic viscosities at 100° C. within the range between about 1.8 cSt and 30 cSt, from a waxy feed having an initial boiling point of about 340° C. or less and a final boiling point of about 560° C. or higher, said process comprising (a) isomerizing at least a portion of the waxy feed, whereby the amount of isoparaffins present are increased; (b) distilling a first portion of the isomerized waxy feed in light block mode operation into at least three base oil fractions having different boiling ranges; (c) distilling a second portion of the isomerized waxy feed in medium block mode operation into at least three base oil fractions having different boiling ranges; and (d) blending at least one base oil fraction produced from light block mode with at least one base oil fraction produced from medium block mode to produce a lubricating base oil blend meeting a target value for at least one pre-selected property.
