Abstract: This invention is related to the use of ionic liquids of general formula C+A?, where C+ represents a cation of organic or inorganic type, specifically of the type imidazolium, pyridinium or ammonium salts, while the anion A? are derivatives which are halides, salts of iron (III), aluminum salts (III), acetate and benzoate, though not exclusively. These agents act as ionic liquid extractants of nitrogenous compounds present in hydrocarbon streams through a process of liquid-liquid extraction thereby can be reduced by more than 60% the content of these contaminants in hydrocarbon streams.

Abstract: An environmentally friendly composition and related methods of use and production of an asphalt prime coat, suitable for application to a base road structure, are described herein. The composition includes an asphaltine, and an emulsion of a natural hydrocarbon resin mixed with a penetrating component, which can include a very limited quantity an organic solvent, or can omit organic solvents. If organic solvents are omitted, a hydrophobic wax can be added for moisture retention and water impermeability. Dispersion agents can be used to facilitate penetration into the base road. Rheology modifying agents and/or alcohols can be used to add flexibility, decrease curing time, and improve thickness and viscosity. The prime coat contains a lower quantity of volatile organic compounds than conventional prime coats, reducing environmental impact. The drying time of the composition is less than alternative compositions.

Abstract: Described herein is a catalyst precursor composition comprising at least one metal from Group 6 of the Periodic Table of the Elements, at least one metal from Groups 8-10 of the Periodic Table of the Elements, and a reaction product formed from (i) a first organic compound containing at least one amine group, and (ii) a second organic compound separate from said first organic compound and containing at least one carboxylic acid group. A process for preparing the catalyst precursor composition is also described, as is sulfiding the bulk mixed metal oxide catalyst precursor composition to form a hydroprocessing catalyst.

Abstract: Described herein is a catalyst precursor composition comprising at least one metal from Group 6 of the Periodic Table of the Elements, at least one metal from Groups 8-10 of the Periodic Table of the Elements, and a reaction product formed from (i) a first organic compound containing at least one amine group and at least 10 carbon atoms or (ii) a second organic compound containing at least one carboxylic acid group and at least 10 carbon atoms, but not both, wherein the reaction product contains additional unsaturated carbon atoms, relative to the first or second organic compound, wherein the metals of the catalyst precursor composition are arranged in a crystal lattice, and wherein the reaction product is not located within the crystal lattice. A process for preparing the catalyst precursor composition is also described, as is sulfiding the catalyst precursor composition to form a hydroprocessing catalyst.

Abstract: A process for recovering ionic liquids comprising the steps of: providing a first ionic liquid mixture, the first ionic liquid having a halogen metallate anion, the mixture containing an organic solvent; adjusting the pH of the mixture to pH 7-10 by the addition of a base to form a first precipitate; separating the first precipitate from the mixture; removing the organic solvent from the first mixture to form a second precipitate and separating the second precipitate from the first mixture; acidifying the resulting mixture to pH 2-7 by the addition of an acid; and drying the mixture to obtain a second ionic liquid having a halogen anion.

Abstract: Ionic liquids of the general formula C+A? where C+ represents an organic cation, specifically, but not limited to the imidazolium, pyridinium, isoquinolinium, ammonium types, which have aliphatic and aromatic substituents, while A? represents a carboxylate, aromatic and aliphatic anion. The ionic liquids are synthesized under conventional heating or microwave irradiation This invention is also related to the application of ionic liquids to remove sulfur compounds of naphthas through a liquid-liquid extraction and the recovery and reuse of ionic liquids by the application of heat, reduced pressure and washing with solvents.

Abstract: Systems and methods consistent with the principles of the present invention address the need to more conveniently and efficiently transfer value to a card issuer. Specifically, in systems and methods consistent with the invention, funds to be applied as a payment to an account are received at a point-of-sale location from a cardholder. These funds may include cash, check, credit card, money order, cashier's check, or other cash equivalent. A transaction message, indicating a payment transaction and a payment amount, is sent from the point-of-sale location to the card issuer. The card issuer then verifies the account information indicated in the transaction message. When the point-of-sale location then receives an indication that the payment amount was applied to the account, the point-of-sale location forwards the payment to the card issuer.
