Abstract:
A method for decreasing the level of organic fluorides present in a hydrocarbon mixture comprising an alkylation reaction product produced from the alkylation of an olefin with an isoparaffin, said method comprising the steps of:passing said hydrocarbon mixture to an eductor;educting into said hydrocarbon mixture a catalyst comprising a volatility reducing additive and hydrofluoric acid to thereby form a hydrocarbon-catalyst mixture;permitting said hydrocarbon-catalyst mixture to undergo a phase separation to thereby produce a hydrocarbon phase having a lower concentration of at least one organic fluoride than said hydrocarbon mixture and to thereby produce a catalyst phase;withdrawing at least a portion of said catalyst phase for use as said catalyst; andwithdrawing at least a portion of said hydrocarbon phase to form a hydrocarbon product stream.
