摘要:
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.

A process for removing a contaminant from a kerosene stream using a lactamium based ionic liquid is described. The process includes contacting the kerosene stream comprising the contaminant with a lean kerosene-immiscible lactamium ionic liquid to produce a mixture comprising the kerosene and a rich kerosene-immiscible lactamium ionic liquid comprising at least a portion of the removed contaminant; and separating the mixture to produce a kerosene effluent and a rich kerosene-immiscible lactamium ionic liquid effluent comprising the rich kerosene-immiscible lactamium ionic liquid.

Processes for removing sulfur and nitrogen contaminants from hydrocarbon streams are described. The processes include contacting the hydrocarbon stream comprising the contaminant with lean carbenium pseudo ionic liquid or a combination of carbenium pseudo ionic liquid and ionic liquid to produce a mixture comprising the hydrocarbon and rich carbenium pseudo ionic liquid or carbenium pseudo ionic liquid and ionic liquid comprising the contaminant. The mixture is separated to produce a hydrocarbon effluent and a rich carbenium pseudo ionic liquid or carbenium pseudo ionic liquid and ionic liquid effluent comprising the rich carbenium pseudo ionic liquid or carbenium pseudo ionic liquid and ionic liquid comprising the contaminant.

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.
摘要:
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.

Processes and apparatuses converting poly- and perfluoroalkyl substances (PFAS). An oxidation reaction zone, preferably a thermal oxidizer, is used to oxidize the PFAS into fluoride species. A reaction zone having at least one reactor containing a solid reactant for neutralizing the fluoride species is provided. The solid reactant is also configured to degrade any PFAS remaining in the effluent from the oxidation zone. A cooling zone, for example, a quench zone may be between the reaction zone and the oxidation zone. The PFAS may be liquid PFAS that is injected into the thermal oxidizer.
