Abstract: The present invention relates to a process for preparing alkylate comprising the subsequent steps (a), (b) and (c): (a) an alkylation step, wherein in a reaction zone a hydrocarbon mixture comprising at least an isoparaffin and an olefin is reacted with an ionic liquid catalyst to obtain an effluent comprising alkylate and solids, which latter are formed as side products in the alkylation step; (b) a separation step, wherein at least part of the alkylate-comprising effluent coming from the reaction zone is separated in a separator unit into a hydrocarbon-rich phase and an ionic liquid catalyst-rich phase which latter phase also comprises solids formed as side products during the alkylation reaction; and (c) a solids removal step, wherein the solids in ionic liquid catalyst-rich phase are separated from the ionic liquid catalyst using a suitable separating device; wherein the process further comprises a step following the separation step (b) and prior to the solids removal step (c).

Abstract: The present invention relates to a composite ionic liquid comprising ammonium cations and composite coordinate anions derived from two or more metal salts, wherein at least one metal salt is an aluminium salt and any further metal salt is a salt of a metal selected from the group consisting of Group IB elements of the Periodic Table, Group IIB elements of the Periodic Table and transition elements of the Periodic Table, wherein the ammonium cation is a N,N′-disubstituted imidazolium cation, the substituents independently being selected from C1-C10 alkyl, and C6-C10 aryl. The composite ionic liquid of the invention is a stable catalyst, which can suitably be used to run an ionic liquid alkylation process which produces less solids and an alkylate product comprising less organic chlorides as side products than processes known from the prior art.
