Integrated micro-reactors for hydrogen synthesis via methane reforming

A system of a plurality of micro-reactors comprising:

• a first set of the micro-reactors;
• at least a second set of the micro-reactors;
• a first reagent feed network in fluid communication with the first set of the micro-reactors;
• a second reagent feed network in fluid communication with the second set of the micro-reactors;
• at least one controller to control independently a feed of reagent to the first reagent feed network and to the second reagent feed network.

A matrix of micro-reactors for a reforming process comprising:

• a plurality of micro-reactors, the micro-reactors including
• a cold side and a hot side opposite the cold side, the micro-reactors configured to be supported by the cold side, the hot side configured to be exposed to a heat source,
• inlets defined in the cold side, the inlets configured for receiving reagents,
• an outlet defined in the cold side, the outlet configured for exiting reforming products,
• a reforming chamber in the hot side, the at least one reforming chamber having a catalyst, the reforming chamber configured for reforming the reagents into the reforming products,
• a reagent path from the inlets to the reforming chamber, the reagent path configured to feed a plurality of channels with reagents, and
• a reforming product path from the reforming chamber to the outlet, the reforming product path configured to receive products from the return plenum;
• and
• a common structure, the micro-reactors being connected by the cold side to the common structure, the common structure having conduit networks configured to feed the inlets of the micro-reactors with reagents and configured to receive products from the outlets of the micro-reactors;
• wherein the hot sides of adjacent ones of the micro-reactors are separated by gaps.
