US Classification:

6064113, 60517, 606411, 606412, 60659, 60398

Abstract:

A thermodynamic engine is configured to convert heat provided in the form of a temperature difference to a nonheat form of energy. Heat is directed through a heating loop in thermal contact with a first side of the thermodynamic engine. A second side of the thermodynamic engine is coupled to an environmental cooling loop in thermal contact with an environmental cooling device. The thermodynamic engine is operated to dispense heat from the second side of the thermodynamic engine through the environmental cooling loop into the environmental cooling device. Operation of the thermodynamic engine thereby generates the nonheat form of energy from the temperature difference established between the first side and the second side of the thermodynamic engine.

Assignee:

Huntsman Petrochemical Corporation - The Woodlands TX

International Classification:

C10M 141/08

US Classification:

508318000

Abstract:

This invention is directed to lubricating compositions which contain detergent-dispersant components derived from substantially linear alkylbenzenes including sulfonates, overbased sulfonates, and salts and esters thereof. Detergents provided by the invention have a low content of the 1-aryl isomers than materials of prior art. In addition, the detergents of the present invention are prepared using alkylbenzene mixtures which have substantially-reduced benzene content over materials provided by the prior art. The invention provides compositions which are useful in formulating lubricants, motor oils, and the like.

US Classification:

554 95, 554220, 554162

Abstract:

A surface active agent comprising an arylated methyl ester of a fatty acid, or mixture of fatty acids, derived from biodiesel or a triglyceride source is disclosed. The fatty acid mixture is condensed to methyl esters and alkylated with aromatic substituents under Friedel-Crafts conditions. The alkylated methyl esters may be alkoxylated using a catalyst derived from fatty acids, alkaline earth salts, and strong acids. The resulting nonionic surfactant may also be sulfonated to produce one class of anionic surfactants. The alkylated methyl esters may also be directly sulfonated to produce another class of anionic surfactants.

International Classification:

C07C 2/70
B01J 19/24

Abstract:

The present disclosure describes a process for the production of alkylaromatics that may be performed using a loop reactor comprising the steps of: introducing an alkylatable aromatic compound; introducing an olefin; introducing a catalyst; adjusting the alkylatable aromatic compound to a pre-reaction temperature that is below a desired reaction temperature; optionally, adjusting the olefin to a second pre-reaction temperature that is below the desired reaction temperature; optionally, adjusting the catalyst to a third pre-reaction temperature that is below the desired reaction temperature; initially contacting the catalyst and olefin under conditions to control the temperature of the reaction of the catalyst and olefin; mixing and/or circulating the alkylatable aromatic compound, the olefin and the catalyst; and maintaining the alkylatable aromatic compound and olefin at the desired reaction temperature.

International Classification:

H01M 8/06
C10J 3/72
C10J 3/10

Abstract:

Methods are disclosed for extracting hydrogen from a biomass compound comprising carbon, oxygen, and hydrogen. The biomass may include cellulose, lignin, and/or hemicellulose. Water is combined with the compound to produce a wet form of the compound. The wet form of the compound is transferred into a reaction processing chamber. The wet form of the compound is heated within the reaction chamber such that elements of the compound dissociate and react, with one reaction product comprising hydrogen gas. The hydrogen gas is processed to generate electrical power.
