Abstract: A process includes flowing a catalyst composition comprising catalyst particles into a radial flow moving bed reactor, wherein the catalyst particles move by gravity through the radial flow moving bed reactor to an exit point of the radial flow moving bed reactor, wherein the catalyst particles form a moving catalyst bed in the radial flow moving bed reactor, flowing a light hydrocarbon feed stream comprising C1 to C3 alkanes into the radial flow moving bed reactor in a manner so that the light hydrocarbon feed stream flows radially inward or radially outward through the moving catalyst bed and thereby contacts the catalyst particles under reaction conditions to produce a product effluent stream comprising a C2 to C10 hydrocarbon product and hydrogen, and flowing the product effluent stream from the radial flow moving bed reactor.

Abstract: 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 %.
