摘要： The invention relates to a method for treating a catalytic reactor comprising a catalytic bed, successively comprising: a) a step of passivation leading to the production of an oxidation layer on the surface of the active sites of the catalytic bed; b) a step of opening the reactor, and c) a step of skimming at least part of the catalytic bed.

摘要： 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) : [RhxNiyMglAlm(OH)2]z+ (An-z/n) kH2O, wherein An- is mainly a silicate or a polysilicate anion ; 0 ≤ x ≤ 0.3; 0 ≤ y ≤ 0.9; 0 ≤ l ≤0.9; 0 ≤ m ≤0.5; 0 ≤ k ≤ 10; x + y > 0; 0.5 ≤ y + l ≤ 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) : [AzA'1-z][B1-x-yNix Rhy]O3-δ (II) wherein A and A' are different and are selected from the Lanthanide or the Actinide families or from the group IIa of 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 ≤ x ≤ 0.7, 0 ≤ y ≤ 0.5, 0 ≤ x+y ≤ 0.8, 0 ≤ z ≤ 1 and δ is 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.
