20150093313 | IONIC LIQUID AND SOLVENT MIXTURES FOR HYDROGEN SULFIDE REMOVAL - The invention comprises a process for removal of hydrogen sulfide from gaseous mixtures. The process involves the use of a mixture of a physical absorption solvent and an ionic liquid. The mixtures provided improved absorption of hydrogen sulfide, when compared to physical absorption solvents without the ionic liquid at low partial pressures of hydrogen sulfide. A regeneration cycle involving the addition of a solvent, such as water, is used to regenerate the mixture. | 04-02-2015 |
20150314281 | REGENERATION OF AN ACIDIC CATALYST BY BORANE ADDITION - A method of regenerating an acidic catalyst is described. A borane compound is contacted with an acidic catalyst that contains conjunct polymer, which releases the conjunct polymer from the acidic catalyst. The acidic catalyst can then be re-activated with acid. The conjunct polymer can be separated from the borane compound, and the borane compound can be recycled. | 11-05-2015 |
20150315095 | HYDROCARBON CONVERSION PROCESS INCLUDING CATALYST REGENERATION - A hydrocarbon conversion process is described. The process includes contacting a hydrocarbon feed with an acidic catalyst under hydrocarbon conversion conditions in a hydrocarbon conversion zone. The hydrocarbon feed reacts to form a mixture comprising reaction products, the acidic catalyst, and deactivated acidic catalyst containing conjunct polymer. The mixture is separated into at least two streams, a first stream comprising the reaction products and a second stream comprising the deactivated acidic catalyst. The reaction products are recovered. The deactivated acidic catalyst is contacted with at least one silane or borane compound in a regeneration zone under regeneration conditions, the conjunct polymer reacting with the at least one silane or borane compound resulting in a catalyst phase and an organic phase containing the conjunct polymer and at least one silyl or boryl compound. | 11-05-2015 |
20150316518 | METHOD FOR QUANTITATION OF ACID SITES IN ACIDIC CATALYSTS USING SILANE AND BORANE COMPOUNDS - A method of quantifying an amount of Brønsted acid sites in an aluminum chloride-containing catalyst is described. The method involves adding a known amount of at least one silane or borane compound to the aluminum chloride-containing catalyst being analyzed. The Brønsted acid sites in the aluminum chloride-containing catalyst react with the silane or borane compound to form a silyl boryl compound, resulting in a catalyst phase and a hydrocarbon phase which contains the silyl or boryl compound. The amount of silyl or boryl compound in the hydrocarbon phase is measured. From the measured amount of silyl or boryl compound formed, the amount of Brønsted acid sites can be determined. | 11-05-2015 |
20150316519 | METHOD FOR QUANTITATION OF ACID SITES IN ACIDIC IONIC LIQUIDS USING SILANE AND BORANE COMPOUNDS - A method of quantifying an amount of Brønsted acid sites in an acidic ionic liquid is described. The method involves adding a known amount of at least one silane or borane compound to the acidic ionic liquid being analyzed. The Brønsted acid sites in the acidic ionic liquid react with the silane or borane compound to form a silyl or boryl compound, resulting in an ionic liquid phase and a hydrocarbon phase which contains the silyl or boryl compound. The amount of silyl or boryl compound in the hydrocarbon phase is measured. From the measured amount of silyl or boryl compound formed, the amount of Brønsted acid sites can be determined. | 11-05-2015 |
20150321977 | HYDROCARBON CONVERSION PROCESSES USING LACTAMIUM-BASED IONIC LIQUIDS - A hydrocarbon conversion process is described.

20150322353 | CONTAMINANT REMOVAL FROM HYDROCARBON STREAMS WITH LACTAMIUM BASED IONIC LIQUIDS - A process for removing a contaminant from a hydrocarbon stream using a lactamium based ionic liquid is described. The process includes contacting the hydrocarbon stream comprising the contaminant with a lean hydrocarbon-immiscible lactamium ionic liquid to produce a mixture comprising the hydrocarbon and a rich hydrocarbon-immiscible lactamium ionic liquid comprising at least a portion of the removed contaminant; and separating the mixture to produce a hydrocarbon effluent and a rich hydrocarbon-immiscible lactamium ionic liquid effluent comprising the rich hydrocarbon-immiscible lactamium ionic liquid. | 11-12-2015 |
