Composition characterized in that it essentially consists in a solid solution of a mixture of at least a Magnesium oxide type phase compound and at least a Magnesium silicate type phase compound in which Al, and Rh and/or Ni cations are soluted, prepared from an (HT) precursor represented by the general formula (I): [RhxNiyMg1Alm(OH)2]z+(An-z/n)kH2O, wherein An- is a silicate or a polysilicate anion, 0≤x≤0.3; 0≤y≤0.9; 0≤1≤0.9; 0≤m≤0.5; x+y>0; 0.5≤1+y≤0.9; 0≤k≤10; x+y+I+m=1; and z is the total electrical charge of the cationic element. Use of a composition as catalyst of the partial oxidation of natural gas and/or light hydrocarbons (C2-C4) to synthesis gas and/or selective oxidations. |
