A method for improving wear control, while maintaining or improving fuel efficiency, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and (i) at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) or (ii) a mixture of at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) and at least one detergent (i.e., an alkali metal or alkaline earth metal salt of an organic acid, or an alkali metal or alkaline earth metal salt of an inorganic acid, or an alkali metal or alkaline earth metal salt of a phenol, or mixtures thereof (e.g., calcium salicylate and/or magnesium sulfonate)), as a minor component. The lubricating oils are useful in internal combustion engines.

Lubricating oil compositions with engine wear protection

Provided are lubricant compositions and hydrocarbon fluids including one or more lubricant base stocks and an effective amount of one more zero SAP antiwear additives and/or corrosion inhibitor additives, wherein the one more antiwear and/or corrosion inhibitor additives include one or more functionalized polyolefins having one or more pyridazine moieties. Such compositions exhibit improved anti-wear, friction reduction and anti-corrosion properties.

Functionalized polymers and oligomers as corrosion inhibitors and antiwear additives

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.

Method and systems to remove polar molecules from refinery streams

Supported metallic catalysts comprised of a Group VIII metal, a Group VIB metal, and an organic additive, and methods for synthesizing supported metallic catalysts are provided. The catalysts are prepared by a method wherein precursors of both metals are mixed and interacted with at least one organic additive, dried, calcined, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks.

High activity supported distillate hydroprocessing catalysts

A two stage process for selectively hydrodesulfurizing olefinic and sulfur and nitrogen-containing naphtha feedstreams wherein the first stage is a nitrogen removal stage to produce a naphtha feedstream having reduced levels of nitrogen compounds and a second stage wherein the naphtha feedstream having reduced levels of nitrogen compounds is hydrodesulfuried with a catalyst and under conditions selective to remove sulfur with minimum olefin saturation.
