1. A system for regenerating ionic liquid with solid regeneration catalyst and hydrogen, the system comprising:
a plurality of tubular reactors, each tubular reactor having a first end secured to an inlet coupling and a second end opposite the first end and secured to an outlet coupling, each tubular reactor comprising a metal material, and each tubular reactor orientated vertically;
a first line configured to supply separated ionic liquid to the first ends of the tubular reactors of the plurality of tubular reactors;
a solid active particulate material disposed in each of the tubular reactors;
a second line configured to recover an effluent from the second ends of the tubular reactors of the plurality of tubular reactors; and,
a piping arrangement connecting the plurality of tubular reactors,
wherein each of the tubular reactors of the plurality of tubular reactors are modular and configured to be removed from the system, by decoupling from the inlet and outlet couplings, and replaced by another tubular reactor.
