(54) CATALYST (ITS VERSIONS) AND PROCESS OF SYNTHESIS GAS PRODUCTION
(57)
FIELD: catalysts and catalytic production processes. SUBSTANCE: catalyst for production of synthesis gas by selective oxidation of methane with oxygen in reaction mixture and excessive methane based on oxide with structure - perovskit containing rare-earth and transition elements. Catalyst is distinguished by the fact that it additionally contains a-Al2O3 and includes the following components, wt.%: perovskit ABOx, 5-40; carrier of a-Al2O3 , 60-95; where A is rare-earth element; B is transition element including 3d elements of 4th period of the Periodic table; x is degree of oxidation of A and B and their stoichiometric ration. Process of synthesis gas production is also described. EFFECT: higher conversion of methane and selectivity at high volume velocities of reaction mixture. 7 cl, 1 tbl, 15 ex
