1. A method for producing hydrogen (H2) from hydrocarbon material, comprising:
mixing the hydrocarbon material with an oxidant to form a mixture of the hydrocarbon material and the oxidant;
flowing of the mixture through a porous material, wherein the porous material comprises an inflow surface through which the mixture enters the porous material and an outflow surface through which combustion products and non-combusted portions of the mixture exit the porous material to a downstream space located in front of the outflow surface; and
initiating a first combustion of the mixture in a combustion zone, wherein the combustion zone is located within the porous material or in front of and adjacent to the outflow surface or both,
thereby producing syngas that comprises combustion products of the mixture;
wherein heat generated by the first combustion raises a first temperature of the combustion zone to a combustion temperature sufficiently high to trigger a second combustion of the mixture,
wherein a second temperature in an upstream space behind the inflow surface relative to a direction of flow of the mixture remains below the combustion temperature, and
wherein the combustion zone does not extend outside of the porous material more than 1 mm beyond the outflow surface, and does not extend within the porous material more than a depth of 3 mm from the outflow surface, and the combustion occurs only downstream of the porous material relative to a direction of flow of the mixture.
