RHODIUM METAL MODIFIED NICKEL BASED STEAM REFORMING CATALYST USING HYDROTALCITE-LIKE PRECURSOR AND THE METHOD FOR PRODUCING THEREOF AND THE METHOD FOR PRODUCING HYDROGEN GAS USING THEREOF

摘要

PURPOSE: A nickel-based catalyst, a manufacturing method thereof, and a hydrogen gas manufacturing method thereof are provided to improve the long term endurance of catalyst and effectively control the generation of carbon dipping. CONSTITUTION: A rhodium is dipped into the nickel-based catalyst including nickel, and the magnesium and aluminum of the similarity hydrotalcite structure with a dipping method. It is marked as the Rh-Ni x/Mg y Al. In the chemical formula, x and y are the molar ratio of Ni and Mg about Al. The x is 0.25~1. The y is 0.6~5.5. The x/y is 0.15 ~ 0.45. A precursor solution of hydrotalcite structure contains an aluminum precursor and a magnesium precursor is manufactured. A nickel-based catalyst of the similarity hydrotalcite structure is manufactured. The nickel-based catalyst which is reformed to the rhodium which is marked to the chemical formula is manufactured by dipping the rhodium.
