Application of silica sol products in the field of catalysts

There are two main types of catalysts prepared from silica sol in the petrochemical field:

(1) Low end areas of catalytic cracking units in refineries. This type of catalyst has relatively low requirements for silica sol, and the corresponding product price is relatively low, which belongs to the low-end field of catalyst application.

(2) High-end fields of acrylonitrile and other devices. This type of catalyst has high requirements on silica sol, such as particle size, specific surface area, sodium ion content, etc. The price is also relatively high.

The catalyst industry has extremely high requirements on the performance of silica sol products, such as accurate specific surface area, low sodium content, extremely low sulfate and chloride content, etc.
