    摘要: A process for disproportionating isoparaffins and paraffins in the presence of at least one initiator is disclosed. The product from the disproportionation contains a gasoline range material having a higher octane-rating than the isoparaffins and paraffins in the feed and a diesel range material having a higher cetane number than the isoparaffins and paraffins in the feed.

    摘要: A system and/or process for decreasing the level of at least one organic fluoride present in a hydrocarbon mixture by first passing the hydrocarbon mixture to an eductor and educting into the hydrocarbon mixture a catalyst comprising a volatility reducing additive and hydrofluoric acid to produce a hydrocarbon-catalyst mixture, permitting the hydrocarbon-catalyst mixture to undergo a phase separation to produce a hydrocarbon phase having a lower concentration of at least one organic fluoride than the hydrocarbon mixture and to produce a catalyst phase, and withdrawing at least a portion of the hydrocarbon phase to thereby form a hydrocarbon product stream, are disclosed. In an alternative embodiment, a system and/or process for controlling the concentration of at least one organic fluoride and/or the RON of the hydrocarbon mixture by adjusting the amount of volatility reducing additive present in the catalyst are disclosed.

    摘要: In an HF alkylation process where an acid catalyst regeneration column separates HF acid from ASO and water to provide regenerated catalyst for a catalyst circulation stream, and where buildup of ASO in the catalyst circulation stream is encountered, an improved control scheme uses an on-line analyzer/controller to maintain desired concentrations of HF acid, or ASO or water in the catalyst circulation stream. In one embodoment, a continuously flowing catalyst slip stream is piped to the analyzer/controller for simultaneously determining concentration of HF acid, ASO and water, and in a preferred embodiment the ASO concentration is maintained at a desired low level by manipulating temperature of a stripping fluid charged to a lower section of the column. An alternate manipulated variable is temperature of the acid catalyst feed to the regenerator column. Alternate controlled variables are the HF acid, and water concentration in the catalyst circulation stream.

    摘要: A method for prolonging the life of a defluorinator material contained within an alkylation process product stream defluorination zone used to remove organic fluorides from a product stream produced by an alkylation process that utilizes an alkylation catalyst containing HF and sulfone. The life of the defluorinator material is extended by reducing the amount of organic fluorides produced in the alkylation process through the addition of trifluoromethanesulfonic acid to the HF/sulfone alkylation catalyst.

    摘要: A process for producing an alkylate product having an improved octane value from an olefin stream having a reduced concentration of the butene isomer of isobutylene. The olefin feed stream to the process system is substantially free of isobutylene and can have undergone prior processing to remove isobutylene therefrom. The olefin feed is subjected to an alkylation reaction catalyzed by a mixture of hydrogen fluoride and sulfone.
