Titanium Tungsten Silicon Powder for Catalyst

The titanium tungsten silicon powder for catalyst was used as the carrier of the catalyst, and the preparation step was to preparation of metatitanic acid, preparation of composite particles, and post-treatment.

titanium tungsten silicon powder for catalyst picturePreparation Steps:
Preparation of metatitanic acid: adding oxygen titanium sulfate solution, dispersant, respectively, constant temperature in the reaction kettle, thermostatic mixing and drops of carbonate aqueous solution, adjust pH value to the appropriate scope, continue to stir for solids, washed, dry paint solids and partial titanate particles;
Preparation of composite particles: crushing metatitanic acid particle, soluble in containing tungsten solution of the second reaction kettle, adding Tween 80 to tungsten solution, control a certain temperature for stir heating to dry composite particles obtained from water;
Post-treatment: dry compound granules, post-forging, and obtained the catalyst with titanium tungsten powder products.
The introduction of the tungsten ion is not a simple physical mixing and mechanical mixing, kneading, practice the correct amount of tungsten ion introducing the methods and guarantee of tungsten ion distribution - dispersed reasonable, TiO2 crystal phase structure stability, stable adsorption center is reasonable, specific surface area, strong ability to resist poisoning, high catalytic efficiency, high stable catalytic properties and service life.
