PROCESS FOR PREPARING NICKEL BASED CATALYSTS FOR SCR OF NATURAL GAS

摘要

The present invention relates to a method for manufacturing a nickel-based catalyst for steam carbon dioxide reforming reaction (SCR) of natural gas and, more particularly, to a method for manufacturing a nickel-based catalyst that is represented by Ni/η-Al_2O_3 manufactured by repeatedly impregnating nickel into a spherical eta-alumina support, which has many acid points formed thereon, and drying the impregnated product dozens of times, thus supporting the nickel at high density. A catalyst manufactured by the manufacturing method according to the present invention exhibits excellent catalytic activity even under the severe conditions of high temperature and high pressure when applied to steam carbon dioxide reforming reaction, and has little carbon deposited thereon owing to the excellent durability of the catalyst.
