Claim Text:
1. A method for preparing a nickel-based catalyst for steam carbon dioxide reforming (SCR), comprising: preparing an alumina sol by adding an organic binder and a dispersing agent to an aluminum precursor solution and stirring at 50-90° C. at pH 3-6 and then converting the alumina sol to an alumina gel by heating at 50-90° C.; preparing an η-alumina support by drying the alumina gel at 150-230° C., shaping into a spherical shape and sintering under nitrogen flow; and preparing a nickel-based catalyst represented by Ni/η-alumina by supporting nickel on the η-alumina support by repeating a procedure of impregnating the η-alumina support in a nickel precursor solution and drying at 50-100° C. 10-20 times and then sintering under air flow.
