Abstract
Provided is a selective catalytic reduction (SCR) catalyst containing a carbon material loaded with vanadium and tungsten and a method of preparing the same, and relates to a method of loading vanadium and tungsten on a carbon material that exhibits excellent abrasion resistance and excellent strength and can be easily prepared.
Claims8
A method of preparing a selective catalytic reduction (SCR) catalyst, the method comprising:
- a first process of preparing a mixture of a vanadium (V2O5) and tungsten oxide (WO3)-supported catalyst with titanium dioxide (TiO2);
- a second process of preparing an extrusion of the mixture by extruding the mixture into a desired shape using a vacuum extruder;
- and
- a third process of drying the extrusion and then sintering the extrusion that has been dried;
- wherein the vanadium (V2O5) and tungsten oxide (WO3)-supported catalyst is prepared through processes including:
- a process of dispersing GO or RGO in deionized water;
- a process of dispersing AMV, which is a precursor of vanadium, and AMT, which is a precursor of tungsten, in deionized water;
- a process of mixing, by stirring, resulting substances;
- and
- a process of collecting the vanadium (V2O5) and tungsten oxide (WO3)-supported catalyst through filtering (using a vacuum filtration device), drying, and heat-treating the resulting substances that have been stirred.
