Abstract
A process comprising adjusting a level of conjunct polymers in an ionic liquid catalyst between a low level that favors production of C+ products boiling at 137.8° C. or below and a higher level that favors production of both C+ products boiling at 137.8° C. or below and C+ products boiling above 137.8° C.; wherein the adjusting is done in response to market demand. A process unit, comprising a reactor that operates with an ionic liquid catalyst comprising a low level or a higher level of conjunct polymers, and the alkylation reactor is switched between operating with the low and the higher levels in response to market demand. A process unit, comprising a reactor that operates in an alkylate mode and a distillate mode, and a catalyst regenerator that operates with varying severity to adjust the level of conjunct polymers in response to demand for gasoline or distillate.
