CATALYST OBTAINABLE BY CALCINING A HYDROTALCITE-LIKE PRECURSOR AND ITS USE FOR THE PARTIAL OXIDATION OF METHANE

摘要

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](Az/n)kH2O, wherein A 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.
