PROCESS AND DEVICE FOR PRODUCING SYNTHESIS GAS

摘要

When producing synthesis gas by a catalytic partial oxidation method, the present invention prevents hot spots from generating in the catalyst-packed layer through which a mixed gas is being passed at a high speed. This synthesis-gas production process by a catalytic partial oxidation method comprises passing a mixed gas comprising a starting-material gas including lower hydrocarbons and an oxidizing gas containing oxygen through a fixed bed catalyst layer disposed inside a reactor, thereby converting the mixed gas into synthesis gas comprising hydrogen and carbon monoxide as major components, and is characterized in that the mixed gas is passed through the catalyst layer under such conditions that the Reynolds number at the inlet of the catalyst layer is less than 20.
