A process to synthesize a catalyst performing Water-Gas shift reaction at a temperature more than 300&#xb0; C. using a precursor having general formula [(Cu, Zn)(Al, M)(OH)](A).kHO with M=Al, La, Ga or In, A=CO, 0.33&#x3c;x&#x3c;0.5, 1&#x3c;n&#x3c;3.

Process to synthesize a catalyst performing water-gas shift reaction at a high temperature

Process for treating a catalytic reactor comprising a catalyst bed that includes the successive steps of passivating the catalytic reactor leading to the production of an oxidation layer at the surface of the active sites of the catalyst bed, opening the reactor, and skimming at least one portion of the catalyst bed.

Method of treatment for a catalytic reactor

Chemical combination (C) between an active solid phase which is covalently bound to the surface of an inert solid phase, characterized in that said solid active phase 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 and characterized in that said inert solid phase is either a compound represented by the general formula (I):AlNiRhMgSiO&#x2003;&#x2003;(I)wherein a, b, c, d, and e are integers which are greater than or equal to 0, provided that at least one of the Si, Al, Mg, Rh or Ni elements, which is present in the solid active phase, is also present in the solid inert phase. Use of a catalyst in chemical reactions involving the conversion of hydrocarbonaceous feedstocks.

Process for the preparation of a catalytic specie consisting essentially of a metallic support, which is coated with a ceramic active phase layer, mainly compound of the general formula (I):[RhNiMgAl(OH)](A)kHO,&#x2003;&#x2003;(I)wherein Ais mainly a silicate or a polysilicate anion; 0&#x2266;x&#x2266;0.3; 0&#x2266;y&#x2266;0.9; 0&#x2266;l&#x2266;0.9; 0&#x2266;m&#x2266;0.5; 0&#x2266;k&#x2266;10; x+y&#x3e;0; 0.5&#x2266;y+l&#x2266;0.9; x+y+l+m=1; and z is the total electrical charge of the cationic element or a compound of the general formula (II):[AA'][BNiRh]O&#x2003;&#x2003;(II)wherein A and A&#x2032; are different and are selected from the Lanthanide or the Actinide families or from the group IIof the Mendeleev's periodical table of elements; B is selected from the transition metal groups of columns IIIb, IVb, Vb, VIb, VIIb, Ib and IIb and group VIIIb of the Mendeleev's periodical table of elements; 0&#x2266;x&#x2266;0.7, 0&#x2266;y&#x2266;0.5, 0&#x2266;x+y&#x2266;0.8, 0&#x2266;z&#x2266;1 andis the sub stoechiometric value of oxygen to obtain the electric neutrality of the Perovskite compound; said process essentially consisting in a step (a) of electro-deposition of said ceramic active phase on said metallic support. Use of said catalytic specie as a catalyst oxidation of gaseous hydrocarbons, to produce synthesis gas.

Process for the preparation of a catalytic specie using electro-deposition

A composition and method for a Catalytic Partial Oxidation (CPO) of methane to synthesis gas. The catalyst allows the process to proceed at low residence time providing a long time thermal stability. The perovskite structure [AA'][BNiRh] Oof the catalyst is obtained using mainly La, Sr, as A and A&#x2032; cation sites (A, A&#x2032;: actinide and/or lanthanide, elements and/or elements from Group I and II) and mainly Fe, Ni, as B cation sites (B: transition metal element and/or element from Group III to V).
