A process for producing renewable distillate-range hydrocarbons is provided. The process includes dehydrating a renewable C2-C6 alcohol feedstock to produce an olefin, oligomerizing the olefin the presence of a halometallate ionic liquid catalyst to produce an oligomer product and hydrogenating the oligomer product or fractions thereof to produce saturated distillate-range hydrocarbons.

Process for the production of renewable distillate-range hydrocarbons

Processes for the direct alkylation of ethylene with isobutane or isopentane using a highly active ionic liquid alkylation catalyst are described. Ethylene is sent to a high-temperature alkylation reactor loop, and C, C, and Colefins are routed to a low temperature alkylation reactor loop. In each reactor, the olefins are contacted with an excess of isobutane or isopentane in the presence of a highly active ionic liquid catalyst. Portions of the reactor effluent streams are fed to a common downstream catalyst separation and product fractionation sections. The remainder of the reactor effluent is recycled back to the respective alkylation reactor.

Combined process for alkylation of light olefins using ionic liquid catalysts

We provide a process for regenerating a spent acidic ionic liquid, comprising contacting the spent acidic ionic liquid with hydrogen and without an addition of a hydrogenation catalyst; wherein a conjunct polymer content is decreased in the spent acidic ionic liquid to produce regenerated acidic ionic liquid. We also provide a process for making an alkylate gasoline blending component, comprising: a) alkylating a mixture of isoparaffins and olefins using an acidic ionic liquid and an alkyl halide or a hydrogen halide, wherein a conjunct polymer accumulates in a spent acidic ionic liquid; and b) feeding the spent acidic ionic liquid and a hydrogen, and without an addition of a hydrogenation catalyst, to a regeneration reactor operated under selected hydrogenation conditions to produce a regenerated acidic ionic liquid that is used for the alkylating, wherein the conjunct polymer in the regenerated acidic ionic liquid is decreased by at least 50 wt %.

Apparatus for regeneration of acidic ionic liquid without addition of a hydrogenation catalyst

We provide systems for ionic liquid catalyzed hydrocarbon conversion that comprise a modular reactor comprising a plurality of mixer modules. The mixer modules may be arranged in series. One or more feed modules are disposed between the mixer modules. Such systems may be used for ionic liquid catalyzed alkylation reactions. Processes for ionic liquid catalyzed hydrocarbon conversion are also disclosed.

Regeneration of acidic ionic liquid without addition of a hydrogenation catalyst

Systems for ionic liquid catalyzed hydrocarbon conversion comprise a reactor vessel, a mixing device in fluid communication with the reactor vessel, and at least one circulation loop in fluid communication with the reactor vessel and the mixing device. The mixing device may comprise an upper venturi, at least one feed injection component, and a lower venturi. Such systems may be used for ionic liquid catalyzed alkylation reactions. Processes for ionic liquid catalyzed hydrocarbon conversion are also disclosed.
