<p>Catalytic process for producing synthesis gas by starting from methane, oxygen and optionally carbon dioxide and water, in which a noble metal catalyst supported on a solid carrier is used, which catalyst is arranged as a cascade of a plurality of catalytic beds, and the process is carried out under adiabatic conditions: -- by feeding the gas reactant stream upstream of the first catalytic bed and removing heat by heat exchange between the catalytic beds arranged in cascade, or -- by introducing the gas reactant stream partially upstream from the first catalytic bed and partially, as a cold stream, between the catalytic beds arranged in cascade, with the proviso that methane is at least partially fed to the first catalytic bed and oxygen is subdivided between all of the catalytic beds.</p> |
