Catalytic system for the production of hydrogen consisting of an active component based on iron and a micro-spheroidal carrier based on alumina and represented by the following formula n [Fe x1 M x2 Q x3 D x4 Al x5 ]O y n wherein n xi with i=1.5 represent the atomic percentages assuming values which satisfy the equation Σxi=100. n y is the value required by the oxidation number with which the components are present in the formulate, n x1 is the atomic percentage with which Fe is present in the formulate and ranges from 5 to 80, preferably from 20 to 50, n M is Cr and/or Mn, n x2 ranges from 0 to 30, preferably from 0 to 10, n Q is La, Lanthanides (with Ce particularly preferred), Zr or a combination thereof, n x3 ranges from 0 to 30, preferably from 0 to 10, n D is Mg, Ca, Ba, Co, Ni, Cu, Zn or combinations thereof, n x4 ranges from 0 to 35, preferably from 5 to 25, n x5 is the atomic percentage with which Al is present in the formulate and ranges from 20 to 95, preferably from 50 to 80. |
