Cobalt‐containing catalysts promoted by noble metals and supported on alumina have been investigated in the reaction of interaction between carbon dioxide and methane at various experimental temperatures and pressures. It was shown that catalysts have a high activity in this reaction. At moderate conditions ( T exp = 853 K, P = 1.0 MPa) the conversion of both carbon dioxide and methane is 30–40% depending on the nature of the second metal. The main reaction products are carbon oxide, hydrogen, water and oxygenates. The yield of the latter reaches 30%. The maximum conversion of both methane (100%) and carbon dioxide (94%) is reached at lower pressure (0.1 MPa) and at 1023 K. In these conditions the synthesis gas is the main reaction product. One of the advantages of the synthesized catalysts is their resistance to coke formation. Copyright © 2000 John Wiley & Sons, Ltd.
