    摘要: 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), wherein an amount of an organic solvent is added to the ionic liquid catalyst-rich phase, which organic solvent has a viscosity which is significantly lower than that of the ionic liquid and which solvent is at least partially miscible with the ionic liquid. The process of the invention provides for more efficient solids removal than processes known from the prior art.

    摘要: Embodiments of methods and apparatuses for isomerization of paraffins are provided. In one example, a method comprises the steps of compressing a C 4 - hydrocarbons-containing stabilizer vapor stream to form a compressed C 4- hydrocarbons-containing stabilizer stream. A C 4 hydrocarbons-containing feed stream that comprises unbranched C 4 hydrocarbons is contacted with a chloride-promoted isomerization catalyst in the presence of hydrogen to form a branched C 4 hydrocarbons-containing reaction zone effluent. At least a portion of the compressed C 4 - hydrocarbons-containing stabilizer stream is combined with the branched C 4 hydrocarbons-containing reaction zone effluent to form a C 4 hydrocarbons-containing combined stream. The C 4 hydrocarbons-containing combined stream is separated into a C 3 - hydrocarbons-containing stabilizer vapor stream and a C 4 hydrocarbons-rich product stream that comprises branched C 4 hydrocarbons.
