Claim Text:
1. A regeneration method, comprising: (a) conducting fuel through at least one first conduit and oxidant through at least one second conduit, the first and second conduits being located in a recuperation zone of a reactor system; (b) combining and reacting at least a portion of the fuel with at least a portion of the oxidant in a mixing-distributing zone to produce heat and a first reaction product, the mixing-distributing zone being located (i) in the reactor system and (ii) downstream of the recuperation zone and upstream of a reaction zone, the mixing-distributing zone comprising a mixer-distributor having a Maldistribution ≦15.0%, a pressure drop ≦0.3 bar, and a combined fuel-oxidant flow rate ≧10.0 kg/hr; and (c) conducting the reaction product through the reaction zone and transferring at least a portion of the heat from the reaction product to the reaction zone; wherein (A)the mixer-distributor comprises a plurality of first orifices in a first location; at least one second orifice at a second location, the first location being upstream of the second location with respect to the fuel-oxidant flow; and a fuel-oxidant flow preventer for preventing fuel-oxidant flow through the mixer-distributor except via the orifices, the fuel-oxidant flow preventer comprising a first plate proximate to the first location and a second plate proximate to the second location, the first orifices being perforations in the first plate and the second orifice being a perforation in the second plate, wherein the number of orifices at the first location is greater than the number of orifices at the second location; (B) (i) the first and second plates are of substantially circular cross-section; (C) the mixer-distributor further comprises third, fourth, and fifth perforated plates of substantially circular cross-section, the fifth plate being upstream of the first plate, the third plate being downstream of the second plate, and the fourth plate being downstream of the third plate, wherein
