Assembly, characterized in that it comprises either a dense layer (CDI), consisting of a material comprising at least 75% by volume and at most 100% by volume of a compound of formula (I): Malpha<SUB>1-x-u</SUB>Malpha'<SUB>x</SUB>Malpha''<SUB>u</SUB>Mbeta'<SUB>y</SUB>Mbeta''<SUB>v</SUB>O<SUB>3-w</SUB>, a porous layer (C<SUB>P1</SUB>), adjacent to the said dense layer (C<SUB>D1</SUB>), consisting of a material comprising at least 75% by volume and at most 100% by volume of a compound of formula (II): Mgamma<SUB>1-x-u</SUB>Mgamma<SUP>40 </SUP><SUB>x</SUB>Mgamma''<SUB>u</SUB>Mdelta<SUB>1-y-v</SUB>Mdelta'<SUB>y</SUB>Mdelta''<SUB>v</SUB>O<SUB>3-w </SUB>and a catalytic layer (C<SUB>C1</SUB>), adjacent to the said dense layer (C<SUB>D1</SUB>) and consisting of a material comprising at least 75% by volume and at most 100% by volume of a compound of formula (III): Mepsilon<SUB>1-x-u</SUB>Mepsilon'<SUB>x</SUB>Mepsilon''<SUB>u</SUB>Meta<SUB>1-y-v</SUB>Meta''<SUB>v</SUB>O<SUB>3-w</SUB>; or a dense layer (C<SUB>D1</SUB>), a porous layer (C<SUB>P1</SUB>), a catalytic layer (C<SUB>C1</SUB>), of thickness E<SUB>C1</SUB>, as defined above; and a second porous layer (C<SUB>P2</SUB>), inserted between the said catalytic layer (C<SUB>C1</SUB>) and the said dense layer (C<SUB>D1</SUB>), consisting of a material comprising at least 75% by volume and at most 100% by volume of a compound of formula (IV): Mtheta<SUB>1-x-u</SUB>Mtheta'<SUB>x</SUB>Mtheta''<SUB>u</SUB>Mkappa<SUB>1-y-v</SUB>Mkappa'<SUB>y</SUB>Mkappa''<SUB>v</SUB>O<SUB>3-w</SUB>, in which assembly at least two of the chemical elements of adjacent layers are identical and one element is different. Novel reactor intended for the production of syngas by the oxidation of natural gas. |
