Abstract: A method for creating work by adsorption end desorption of a working fluid on an fiber sorption system which has a plurality of tubular hollow fibers within a vessel which is connected to a work device. Each fiber is in the form of a tubular, elongated body composed of a sorbent material capable of adsorbing a working fluid such as carbon dioxide. The fibers have an inner surface adjacent the hollow interior and an outer surface, one of which has a coating layer which is impermeable to both a working fluid and thermal fluid.

Abstract: The present invention relates to methods and systems for removing polar molecule contaminants from a refinery stream in connection with the processing of hydrocarbon fluids, chemicals, whole crude oils, blends and fractions in refineries and chemical plants that include adding high surface energy and/or high surface area nanoparticle compounds to a refinery stream to remove the polar molecule contaminants.

Abstract: The invention relates to a hydrocracking process for hydrocracking petroleum and chemical feedstocks using bulk Group VIII/VIB catalysts. Preferred catalysts include those comprised of Ni—Mo—W.

Abstract: This invention relates to base stocks and base oils that exhibit an unexpected combination of high viscosity index (130 or greater) and a ratio of measured-to-theoretical high-shear/low-temperature viscosity at −30C or lower and the methods of making them. Specifically, the present invention relates to low-volatility/low-viscosity lubricant base stocks, lubricant base stocks and base oils, formulated lubricant compositions or functional fluids comprising these base stocks and methods of making them. More particularly, this invention relates to lubricant compositions of low-temperature flow capability and low viscosity for passenger car motor lubricants of SAE 0W-XX grade (where XX=40 or lower), methods for optimizing fuel economy using the same, and methods or processes to produce them.

Abstract: A method for producing a lube basestock from a waxy feed is disclosed in which a feed containing to 50 wt % or more of wax is hydrotreated and stripped to lower the nitrogen and sulfur content of the feed. The feed is then hydroisomerized under conditions to 370° C. hydrocatalytically dewaxed with a catalyst comprising a mixture of a catalytically active metal on a zeolite dewaxing catalyst and an amorphous catalyst, or alternatively is solvent dewaxed and then hydrocatalytically dewaxed with the just described catalyst.

Abstract: Waxy feeds are treated under hydroisomerization conditions to produce good yields of an isomerate product of high VI by using a silica-alumina based catalyst in which the silica-alumina has a pore volume less of 0.99 ml/gm (H2O), an alumina content in the range of 35 to 55 wt % and an isoelectric point in the range of 4.5 to 6.5. A lube fraction of the isomerate is dewaxed to provide a lube basestock of high VI. The silica-alumina may be modified with a rare earth oxide or yttria or boria or magnesia in which instance the modified catalyst has an isoelectric point greater than but no more than 2 points greater than base the silica-alumina.
