TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Catalyst: In the catalyst (A), the metal or metal oxide is selected from Fe, Ti, and Sn, and the noble metal is Pd and/or Pt. The nanoparticles ceria based catalyst is of formula Ce1-xM'xPt/PdyO2-x.M'=Fe, Ti, or Sn;x=0.1-0.33;y=0.01-0.03.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Reformer: In the tube and reformer, the annular passage is filled with the catalyst (A) along the length of the tube, and the porous pipe outer surface is coated with the catalyst (A). The tube has an outside diameter of 25-100 mm. The pipe has an outside diameter of 10-70 mm. Preferred System: In the system for the production of hydrogen from a raw gas, each of the tubes further comprises a porous pipe at a first end within the tube, where the pipe defines an inner passage capped at a second end opposite the first end, and an annular passage between the pipe and the tube that is filled with the catalyst; each of the tubes further comprises a porous pipe at a first end within the tube, where the pipe defines an outer surface and an inner passage capped at a second end opposite the first end, and an annular passage between the pipe and the tube, where the porous pipe outer surface is coated with the catalyst; and a raw gas cleaning system in communication with the raw gas source for cleaning the raw gas prior to the injection of the raw gas into the reformer.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: In the process (P1), the flameless combustion derives from of a mixture of fuel gas and combustion air in presence of the catalyst and involves heating coated outer surface of each tube at 550-750 degrees C; the chemical reaction is carried out at 600-750 degrees C; and the single shift temperature step is carried out at 250-320 degrees C. The process (P1) further involves a step of cleaning the raw gas to be treated prior to the step (b). The separation of hydrogen from carbon dioxide produced in the step (d) involves (a') providing a mixture of hydrogen and carbon dioxide from which hydrogen will be separated; (b') introducing the mixture of hydrogen and carbon dioxide in a vessel comprising an adsorption bed for adsorbing the carbon dioxide and allowing passage of hydrogen through passage to a hydrogen accumulator; (c') flushing the carbon dioxide containing an amount of hydrogen adsorbed on the adsorption bed within the vessel with carbon dioxide and transferring the carbon dioxide containing an amount of hydrogen with the mixture in the step (a'); (d') removing the carbon dioxide within the vessel and transferring to the flameless combustion; and (e') repressurizing the vessel and repeating steps (b') to (d').
