Abstract: An oil composition comprising a first component having pendant groups, a second component having two or more terminal carbon chains, and optionally a third component, where a single molecule of the second component can form shearable stable structure with two molecules of the first component via van der Waals force between pendant groups and the terminal carbon chains. Shear stability of the oil can be improved if the total concentration of the heavy fraction of the shearable stable structure is controlled at a low concentration.

Abstract: An oil composition comprising a first component having pendant groups and a second component but free of a third component and process for making such oil composition, where a single molecule of the third component can form large shearable stable complex structure with two molecules of the first component via van der Waals force between pendant groups and the terminal carbon chains, and a single molecule of the second component is capable of adjoining no more than one molecule of the first type. The oil composition has high shear stability making it suitable for use in lubricants subject to repeated high shear stress events.

Abstract: A feedstock of one or more C4 to C24 alpha olefins is oligomerized with a metallocene catalyst system to form a polyalphaolefin product mixture. At least a portion of the polyalphaolefin product mixture is then isomerized in the presence of an acid catalyst to form an isomerized polyalphaolefin. The polyalphaolefin may also by hydrogenated, either simultaneously with isomerization or afterwards. The resulting polyalphaolefin has a kinematic viscosity at 100° C. of between 1 cSt and 20 cSt and reduced pour point in comparison to the pre-isomerized product.

Abstract: A process for treating a water-acid mixture includes contacting the water-acid mixture with a hydrocarbon solvent to remove at least a portion of the acid from the mixture to produce a treated liquid. The ratio of the hydrocarbon solvent to water-acid mixture is between 2:1 and 5:1.

Abstract: This invention generally relates to a high temperature stable polyol ester lubricant composition containing short chain carboxylic esters and a process for making the same. The polyol ester lubricant compositions are preferably formed from pentaerythritol and a mixture of C2 to C10 carboxylic acids in which (1) from 95 to 80 mole %, based on total acids, are C5 to C10 carboxylic acid, and (2) from 5 to 20 mole %, based on total acids, are at least one C2 to C4 carboxylic acid The polyol ester lubricant compositions of the present invention, specifically those using at least one C2 to C4 carboxylic acid, are useful as base stock for high temperature application such as Aviation Turbine Oils and exhibit enhanced anti-deposition and oxidation stability compared with the base polyol ester compositions while maintaining a good viscosity index.

Abstract: A synthetic ester composition which exhibits thermal and oxidative stability, lower friction coefficient and lower wear, wherein the ester composition comprises the reaction product of: a linear or branched alcohol having the general formula R(OH).sub.n, wherein R is an aliphatic or cyclo-aliphatic group having from about 2 to 20 carbon atoms and n is at least 2; and at least one linear and/or branched acid which has a carbon number in the range between about C.sub.4 to C.sub.20, wherein the synthetic ester composition has a hydroxyl number of between about greater than 5 to 180, preferably between about greater than 5 to 100, and more preferably between about 10 to 80.

Abstract: A method and system to optimize the acid strength and level of total organic carbon (TOC) of process streams in which specific hydrocarbons are extracted from hydrocarbon mixtures by sulfuric acid.

Abstract: A method for improving the octane rating of products from a catalytic cracking system is disclosed. The method is directed at maintaining the metal contaminant level on the cracking catalyst above about 400 wppm equivalent metal and periodically passing the cracking catalyst through a passivation zone having a reducing atmosphere maintained at an elevated temperature to passivate the metal contaminant on the cracking catalyst.

Abstract: An adsorption process for the recovery of hydrogen from a feed gas or vapor which contains hydrogen in admixture with one or more hydrocarbon components, alone or in admixture with non-hydrocarbon components. Particulate adsorbent solids are provided with a magnetizable component, or components, and circulated between an adsorption zone in which hydrogen is concentrated in the off gas by contact of the adsorbent solids with the feed, and hydrogen recovered, and a desorption zone in which the exhausted solids are regenerated. Within the adsorption zone the feed is countercurrently contacted with the solids at relatively low temperature to selectively adsorb hydrocarbons, and perhaps other non-hydrogen components. The solids are formed into a moving, fluidized bed, and magnetically stabilized to suppress gross solids circulation while hydrocarbons are adsorbed from the feed.
