A process for the catalytic transformation of gases containing SO2, with an SO2 content below 9% to obtain SO3 and/or sulfuric acid, with purification and drying of the gases preheating of the gases to be used containing SO2 in exchange for heat with the hot gases containing SO3 and intermediate absorption of the SO3 formed in the first contact stage, characterized in that the degree of transformation in the first contact stage before the intermediate absorption is graduated up to 70 to 80% of the total content in SO2 of the starting gas.
