As one kind preferably, in the terbium salt ethanol solution of step (1), terbium salt is TeCl3、TeCl4、TeF3、TeF4In one Plant or two kinds.
As one kind preferably, in step (2), the alkali lye added in mixed liquor is that KOH ethanol solutions or NaOH ethanol are molten Liquid.Wherein, the solute of KOH ethanol solutions or NaOH ethanol solutions is KOH or NaOH, and solvent is ethanol.
As one kind preferably, in step (1), FeCl2The concentration of ethanol solution be 1-2mol/L, terbium salt ethanol solution it is dense It is 0.1-0.2mol/L to spend, and the concentration of alkali lye is 10mol/L in step (2).
Preferably in step (5), condition is vacuum dried for 75-80 DEG C is vacuum dried, vacuum calcining condition is as a kind of 500 DEG C of vacuum calcinings.
Fe-Ti-Te ternary composite types are economized on coal solid sulfur and coke additive, are removed using Fe-Ti-Te ternary composite types solid sulphur of economizing on coal The preparation method of burnt additive is obtained.
As one kind preferably, Fe-Ti-Te ternary composite types economize on coal solid sulfur and coke additive for dusty material.
Fe-Ti-Te ternary composite types are economized on coal the application of solid sulfur and coke additive, as it is coal-fired economize on coal, solid sulphur, decoking add Plus agent is used.
Generally speaking, the invention has the advantages that：
Materials are simple, easy to make；In final product, Fe-Ti composites primarily serve the solid sulphur of ash content in lifting coal The effect of effect and lifting cinder melt temperature, Fe-Te composites are mainly the activation energy for playing and reducing burning, catalysis combustion Burn, lifting coal combustion efficiency, raising burning constitute the effect of sensible heat caloric value；Help coal-burning utilities energy-saving and emission-reduction.
