A lubricating oil composition formulated with a viscosity index (VI) improver composition including a combination of an ethylene α-olefin copolymer having no greater than 66 mass % of units derived from ethylene, and a linear diblock copolymer including at least one block derived primarily from a vinyl aromatic hydrocarbon monomer, and at least one block derived primarily from diene monomer.

Lubricating oil compositions.

Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to hydrocarbons, ketones and alcohols useful as liquid fuels, such as gasoline, jet fuel or diesel fuel, and industrial chemicals. The process involves the conversion of mono-oxygenated hydrocarbons, such as alcohols, ketones, aldehydes, furans, carboxylic acids, diols, triols, and/or other polyols, to C4+ hydrocarbons, alcohols and/or ketones, by condensation. The oxygenated hydrocarbons may originate from any source, but are preferably derived from biomass.

Synthesis of liquid fuels and chemicals from oxygenated hydrocarbons

Cost, environmental, and performance issues coupled with legislative changes, new engine oil requirements, and technology development for exploration of space and the oceans are changing the lubrication additive market. Reflecting how the need for new applications drives the development of new lubricant additives, Lubricant Additives: Chemistry and

Disclosed are methods for generating propylene glycol, ethylene glycol and other polyols, diols, ketones, aldehydes, carboxylic acids and alcohols from biomass using hydrogen produced from the biomass. The methods involve reacting a portion of an aqueous stream of a biomass feedstock solution over a catalyst under aqueous phase reforming conditions to produce hydrogen, and then reacting the hydrogen and the aqueous feedstock solution over a catalyst to produce propylene glycol, ethylene glycal and the other polyols, diols, ketones, aldehydes, carboxylic acids and alcohols. The disclosed methods can be run at lower temperatures and pressures, and allows for the production of oxygenated hydrocarbons without the need for hydrogen from an external source.

According to the invention, an improved class of amphoteric surfactant having improved surfactant properties characterized as mild and environmentally safe has been provided comprising compounds of the formula: ##STR1## The amphoteric surfactant of the subject invention have at least two hydrophobic moieties and at least two hydrophilic groups per molecule and are useful as emulsifiers, detergents, dispersants and solubilizing agents.

Anionic surfactants having multiple hydrophobic and hydrophilic groups

A process for the production of a lower polyhydric alcohol or a mixture thereof by the hydrogenation and hydrolysis of a carbohydrate. The first stage hydrogenation produces higher polyhydric alcohols, such as sorbitol. In the second stage these higher polyhydric alcohols are selectively converted under the appropriate reaction conditions to lower polyhydric alcohols, such as ethylene glycol and 1,2-propylene glycol, using a sulfide-modified ruthenium catalyst.
