| 摘要 |
The present invention relates to a method for producing an alumina-based catalyst support which is appropriate for producing a selective catalytic reduction catalyst for removing nitrogen oxide by using discarded catalyst waste after high-cost catalyst active metal components are extracted (collected) from a waste catalyst discharged from a desulfurizing step in an oil refinery or the like. A support molded product, which is molded using molding clay produced by combining 20-50 parts by weight of zeolite with respect to 100 parts by weight of the catalyst waste, is dried and plasticized. |
