Process for the preparation of carbon monoxide rich gas comprising reacting a mixed gas of hydrogen and carbon dioxide in the presence of a conversion catalyst to carbon monoxide rich gas, which process further comprises reacting part of the carbon dioxide and hydrogen in the gas feed exothermically to methane simultaneously with the carbon monoxide producing reaction and carrying out both reactions under adiabatic conditions, so that the exothermical methane producing reaction provides necessary heat for the endothermic carbon monoxide producing reaction.
