PURPOSE:To manufacture inexpensively the titled Ru catalyst showing high catalytic activity in the steam-reforming reaction of hydrocarbon or the like by adsorbing organic substances on a carrier previously and depositing ruthenate thereon. CONSTITUTION:Organic substances such as lower alcohol are previously saturated and adsorbed on a carrier of alumina or the like and ruthenate such as sodium ruthenate or potassium ruthenate is deposited thereon. It is reduced to RuO2 by performing the decomposition and reduction of the ruthenate by means of organic substances simultaneously with the deposition of the ruthenate. Then, the harmful metallic atoms such as Na and K are removed by washing it with water till the pH is reached to almost 8 and it is dried to manufacture the catalyst. By this method, the removal of chlorine being catalytic poison and metallic atoms such as Na or K which give adverse effect to the catalyst performance is made easy and the catalyst performance is improved and the Ru catalyst is inexpensively manufactured. |
