    摘要: Disclosed is an alkylation process. The process comprises contacting a hydrocarbon mixture comprising at least one olefin having from 2 to 6 carbon atoms and at least one isoparaffin having from 3 to 6 carbon atoms under alkylation conditions in the presence of an acidic ionic liquid catalyst. The catalyst comprising a mixture of at least one acidic ionic liquid and at least one alkyl halide. The acidic ionic liquid is a chloroaluminate ionic liquid prepared by mixing aluminum trichloride (AlCl 3 ) and a hydrocarbyl substituted pyridinium halide having the general formula A: where R = H, methyl, ethyl, propyl, butyl, pentyl or hexyl group and X is a chloroaluminate; and wherein the isoparaffin and the olefin are alkylated.

    摘要: An HF olefin/isoparaffin alkylation process is carried out in an alkylation unit with a settling vessel in which the alkylate product is separated from the HF acid catalyst containing water and acid soluble oil (ASO). The density of the liquids in the settling vessel is measured at different levels by means of a nuclear density profile analyzer. The acid strength of the acid phase is determined from the density measurement and an optional temperature measurement. The proportion of water in the acid phase may also be measured separately by measurement of its electrical conductivity to determine the respective contributions of the water and the ASO to the density of the HF acid phase.

    摘要: A system and/or process for decreasing the level of at least one organic fluoride present in a hydrocarbon mixture (118) by first passing the hydrocarbon mixture (118) to an eductor (120) and educting into the hydrocarbon mixture a catalyst (122) comprising a volatility reducing additive and hydrofluoric acid to produce a hydrocarbon-catalyst mixture (132), permitting the hydrocarbon-catalyst mixture (132) to undergo a phase separation to produce a hydrocarbon phase (128) having a lower concentration of at least one organic fluoride than the hydrocarbon mixture (132) and to produce a catalyst phase (130), and withdrawing at least a portion of the hydrocarbon phase to thereby form a hydrocarbon product stream (134), are disclosed. In an alternate 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 the volatility reducing additive present in the catalyst are disclosed.
