摘要： A method for preparing a nano suspension lubricant comprises providing substantially spherical nano particles of size ranging from about less than 50 nanometers to about 100 nanometers. The method further comprises mixing the nano particles and a surfactant in about 1:1 ratio in a solvent to form a mixture. The solvent is evaporated from the mixture to obtain surface modified nano particles. The surface modified nano particles include the nano particles coated with the surfactant. The method comprises mixing the surface modified nano particles with a lubricating fluid to form the nano suspension lubricant, where the lubricating fluid comprises about 90% to 99% base oil and about 1% to 10% additives.

摘要： A process for preparing high VI lubricating oil basestocks comprising hydrotreating, hydrodewaxing and optionally hydrofinishing. The hydrotreating step is under conditions such that the amount of conversion to 343° C. minus is less than 5 wt. % of the feedstock and the VI increase is less than 4 VI over the feedstock. Hydrodewaxing uses a low alpha catalyst and hydrofinishing is accomplished with a catalyst based on the M41S family.
