MESOPOROUS NI-FE-RU-AL XEROGEL CATALYST AND THE PREPARATION METHOD THEREOF

摘要

The present invention relates to a mesoporous nickel-iron-ruthenium-alumina xerogel catalyst and a manufacturing method thereof and, more specifically, to a mesoporous nickel-iron-ruthenium-alumina xerogel catalyst comprising 49-68.8 parts by weight of alumina, 30-40 parts by weight of nickel, 1-20 parts by weight of iron and 0.2-1.0 parts by weight of ruthenium. Additionally, the manufacturing method for the catalyst comprises: an alcohol heating step; an aluminum precursor dispersing step; a sol forming step; a sol cooling step; a metal precursor adding step; a sol hydration and condensation step; a gel aging step; a gel drying step; and a gel heat treating step. The catalyst of the present invention is able to improve a conversion rate of carbon dioxide by having high activity at low temperatures and is able to manufacture methane at high yield by being used in the methanation reaction of carbon dioxide. The manufacturing method for the catalyst of the present invention exhibits excellent reproducibility and provides the mesoporous nickel-iron-ruthenium-alumina xerogel catalyst through a simple process.
