Provided is a hydro-regeneration catalyst system, comprising:

Regeneration of an ionic liquid catalyst by hydrogenation using a macroporous noble metal 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.

Systems for ionic liquid catalyzed alkylation based on a modular reactor

Processes for shutting down a regeneration reactor and for removing spent solid from the regeneration reactor may comprise shutting off a feed comprising an ionic liquid to the regeneration reactor, cooling the regeneration reactor, removing at least a portion of the ionic liquid from the regeneration reactor, purging the regeneration reactor with Ngas, introducing water into the regeneration reactor to form an acidic liquid in the regeneration reactor, and dumping the acidic liquid and the spent solid from the regeneration reactor. The acidic liquid may be neutralized with a basic liquid to provide a neutralized liquid. The spent solid may be separated from the neutralized liquid. In an embodiment, noble metal(s) may be recovered from the spent solid.
