The invention discloses an apparatus and process for the reformation of hydrogen containing fluids to hydrogen and other constituents, more particularly, the reformation of hydrocarbons or mixtures of hydrocarbons in a cyclic flow inert porous media reactor for the production of hydrogen and other constituents. In an alternate embodiment, the apparatus and process can be used for the reformation of hydrogen sulfide to produce hydrogen and sulfur. The cyclic flow reactor comprises a reaction chamber filled with a porous media matrix containing an unconstrained reaction zone located in any portion of the reactor chamber. This reactor system employs valves to canalize the reactant mixture and product mixture during flow cycling channeling the reactant mixture through the porous media matrix, and reacting the reactant mixture. In another embodiment, the reactor system may further comprise at least one aperture along the axial length of the reactor casing to enable mounting of an external energy source and/or at least one heat exchanger to provide a source of heat transfer to the inlet pipe and outlet pipe as well as the reactant mixture and product mixtures.

1. A continuous process for the reformation of a reactant mixture in a cyclic flow reactor chamber, the process comprising: applying heat directly to the reactor chamber, the reactor chamber disposed substantially within a reactor casing, and a thermal insulation layer located substantially between the reactor casing and the reactor chamber, wherein the thermal insulation layer forms a wall of the reactor chamber;flowing in a first direction of flow a reactant mixture through a substantially porous media matrix disposed within the reactor chamber;reacting the reactant mixture in the reactor chamber wherein the reacting occurs through a reaction zone;reversing the first direction of flow for the reactant mixture to a second direction of flow;allowing the reaction zone to propagate freely through the reactor chamber;wherein the heat is applied by providing oxidation of a hydrogen containing fuel with an oxygen containing gas, thereby adding fluid flow and chemical species directly to the thermal insulation layer and the reactor chamber comprising the substantially porous media matrix; andwherein the reactant mixture is one or more selected from the group consisting of: a) a fluidic hydrocarbon greater than C2,b) a fluidic hydrocarbon and steam,c) a hydrogen sulfide containing stream,d) ammonia containing stream, ande) mixtures thereof;and wherein the reactant mixture further comprises an oxygen containing gas. 2. The process of claim 1 wherein the reactor chamber is maintained at a temperature between about 500° C. and about 3000° C. 3. The process of claim 1 wherein the reactant mixture comprises a hydrogen sulfide containing stream with a hydrogen sulfide concentration of between about 10% and about 100% by volume of the reactant mixture. 4. The process of claim 1 wherein the reactant mixture comprises a hydrogen sulfide containing stream and has an equivalence ratio greater than about 1 and less than about 20. 5. The process of claim 1 wherein the reactant mixture comprises hydrogen sulfide and the reactant mixture has a residence time through the reactor chamber between about 0.1 and about 250 seconds. 6. The process of claim 1 wherein the heat is applied by an external energy source mounted on at least one aperture outside of the reactor casing, the external energy source providing heat to the porous media. 7. The process of claim 1 further comprising providing cooling fluid to the reactor system to facilitate heat transfer.
