With the development of the petroleum industry, the research, development and application of tungsten-based catalysts have received extensive attention. This type of catalyst is usually impregnated by metatungstate money on the catalyst carrier such as spherical silicon and aluminum oxide. During the preparation, it is necessary to ensure that there is enough active ingredient (WO3) attached to the catalyst substrate. Catalyst RN-10 For example, its WO3 content accounts for about 29.5%-29.8%. Therefore, the unique high water solubility of ammonium metatungstate makes it an ideal raw material for the preparation of tungsten-based catalysts.
