A METHOD FOR PREPARING MIXED METAL OXIDE HAVING ZINC AND HYDROGENATION REACTION CATALYST PREPARED THEREFROM

摘要

A manufacturing method of zinc-comprising mixed metal oxide is provided to form uniform particles by using a distributed system and to manufacture method of producing a catalytic of the mixed metal oxide containing a zinc of which an average diameter mostly is less than 200 nm. A mixed solution containing a metal precursor and a molding material is manufactured. The metal precursor is made of one or more materials and a zinc precursor. The one or more materials are selected from chrome precursor, aluminum precursor or a barium precursor. The coprecipitation material is manufactured by injecting precipitation agent into the mixed solution. A zinc-comprising mixed metal oxide of a chemical formula 1 (Zn_a-Cr_b-Al_c-Ba_d-O_e) is manufactured by drying and plasticizing the obtained coprecipitation material. In the chemical formula 1, a is a molar ratio of a Zn atom, B is a molar ratio of a Cr atom, C is a molar ratio of an Al atom, D is a molar ratio of a Ba atom and E is a molar ratio of an O atom.
