Are there any classmates who work in a catalyst factory? I would like to ask what are the current mainstream raw materials for molybdenum hydrorefining catalysts? Ammonium dimolybdate/ammonium heptamolybdate, or high-purity molybdenum oxide? Thanks!

In the past, we used ammonium heptamolybdate, but now the situation is not clear anymore.

Thank you. Now it is said that highly soluble molybdenum oxide is used for dilution and then impregnation. Is this correct? Does any hero know?

It is said that co-impregnation method is generally used in industry to prepare hydrogenation catalysts. Is this correct? Does anyone know which method of kneading, step impregnation or co-impregnation is more commonly used in industry? Thanks
