Document Type and Number:
Japanese Patent JP2716092
Kind Code:
B2
Abstract:
PURPOSE:To improve hydrocarbon with water vapor in a low ratio of steam to carbon and prolong life of catalyst by using a catalyst layer comprising catalysts carrying ruthenium, rhodium and nickel in a fixed ratio. CONSTITUTION:Hydrocarbon and water vapor are supplied into a catalyst layer composed of upstream-side catalyst layer and downstream-side catalyst layer to improve the hydrocarbon. Said upstream-side catalyst layer contains 10 to 50vol.% catalyst carrying ruthenium or rhodium on zirconia carrier to total catalyst.
