Abstract: An alkylation process system uses an ionic liquid as a catalyst which undergoes an interruption in normal operating condition. A method of maintaining the alkylation process system during the interruption of the normal operating condition requires maintaining a circulation of the ionic liquid through the alkylation process system without interruption.

Abstract: Methods and apparatuses are provided for producing hydrocarbons. A method includes contacting an aromatic rich feed stream including diolefins with a catalyst in the presence of hydrogen to react the diolefins with the hydrogen to produce mono-olefins. A deposit forms on the catalyst during reaction. The deposit is removed from the catalyst with a solvent, where the solvent includes about 50 mass percent or more aromatic compounds.
