20090170687 | System and apparatus for ionic liquid catalyst regeneration - Disclosed are a system and an apparatus for regenerating an ionic liquid catalyst, which has been deactivated by conjunct polymers during any type of reaction producing conjunct polymers as a by-product, for example, isoparaffin-olefin alkylation. The system and apparatus are designed such that solvent extraction of conjunct polymers, freed from the ionic liquid catalyst through its reaction with aluminum metal, occurs as soon as the conjunct polymers de-bond from the ionic liquid catalyst. | 07-02-2009 |
20090170688 | Process for ionic liquid catalyst regeneration - A regeneration process for re-activating an ionic liquid catalyst, which is useful in a variety of reactions, especially alkylation reactions, and which has been deactivated by conjunct polymers. The process includes a reaction step and a solvent extraction step. The process comprises (a) providing the ionic liquid catalyst, wherein at least a portion of the ionic liquid catalyst is bound to conjunct polymers; and (b) reacting the ionic liquid catalyst with aluminum metal to free the conjunct polymers from the ionic liquid catalyst in a stirred reactor or a fixed reactor. The conjunct polymer is then separated from the catalyst phase by solvent extraction in a stirred extraction or packed column. | 07-02-2009 |

20100130800 | Liquid-Liquid Separation Process Via Coalescers - A process for separating an ionic liquid from hydrocarbons employs a coalescer material having a stronger affinity for the ionic liquid than the hydrocarbons. The coalescer material can be a high surface area material having a large amount of contact area to which ionic liquid droplets dispersed in the hydrocarbons may adhere. The process includes feeding a mixture comprising ionic liquid droplets dispersed in hydrocarbons to a coalescer comprising the coalescer material. The process further includes a capture step involving adhering at least a portion of the ionic liquid droplets to the coalescer material to provide captured droplets and a coalescing step involving coalescing captured droplets into coalesced droplets. After the capture and coalescence steps, the coalesced droplets are allowed to fall from the coalescer material to separate the ionic liquid from the hydrocarbons and provide a hydrocarbon effluent. | 05-27-2010 |
