Title:
METHOD FOR PREPARING MULTICOMPONENT FERRITE METAL OXIDE CATALYST
Document Type and Number:
WIPO Patent Application WO/2017/116153
Kind Code:
A1
Abstract:
An embodiment of the present invention provides a method for preparing a multicomponent ferrite metal oxide catalyst, the method comprising: (a) a step for preparing a precursor solution by dissolving nitrate precursors of each of magnesium, aluminum, iron, and a divalent metal cation in a polar solvent; (b) a step for forming a catalyst powder by thermally decomposing the precursor solution while spraying the precursor solution into a reactor using a carrier gas; and (c) a step for calcining the catalyst powder in a storage tank after transporting the catalyst powder to the storage tank.
