INTEGRATION OF HYDRO-DECHLORINATION AND HYDRO-REGENERATION

摘要

We provide an integrated process to produce alkylate gasoline, comprising: a. alkylating a mixture of hydrocarbons using a chloride-containing ionic liquid catalyst in an alkylation reactor to produce an alkylate gasoline comprising a chloride contaminant; b. hydro-regenerating the chloride-containing ionic liquid catalyst in a hydrogenation reactor; c. hydro-dechlorinating the alkylate gasoline comprising the chloride contaminant in a dechlorination reactor at a dechlorination pressure from 0 to 6895 kPa (0 to 1000 psig) of a hydrogenation pressure used in the hydrogenation reactor, to produce a dechlorinated alkylate gasoline; and d. feeding an off-gas, comprising 70 to 99.9 vol% hydrogen, from the dechlorination reactor to the hydrogenation reactor. We also provide an integrated alkylation process unit for conducting this process.
