colloidal silica to catalysts industry

  Due to its advantages of small particle size, large specific surface area and good chemical stability, colloidal silica has been widely used as a catalyst carrier in the fields of automobile exhaust three-way catalytic device, thermal power plant exhaust gas denitrification catalytic device, and petrochemical product catalytic production.

  The catalyst made  colloidal silica has the following characteristics:

(1) Good catalyst stability;

(2) High catalytic strength;

(3) Good catalytic reaction performance;

(4) The catalyst has strong anti-metal poisoning ability;

(5) The pore structure and activity of the catalyst can be adjusted. 

Although the preparation of catalysts from colloidal silica has received more and more attention, issues such as particle size distribution and system purity of colloidal silica raw materials still restrict the production of high-performance catalyst products. The unreasonable particle size distribution in the silica sol raw material will affect the bonding strength of the prepared catalyst, and the low purity will cause the "poisoning" phenomenon of the loaded precious metals, which will affect the catalytic effect of the catalyst. 

In response to the above problems, our company has developed silica sol products for catalysts. The features of our colloidal silica products for catalysts are as follows:

(1) The particle morphology is uniform and the particle size distribution is reasonable.

(2) The content of metal ion impurities is low and the purity is high. 

  Our company can customize the particle size distribution, specific surface area, purity and other performance parameters of colloidal silica products according to the specific requirements of customers to meet the individual needs of customers. Relying on the rich experience accumulated in the production and application of catalyst-specific colloidal silica products, we have been committed to the research and development of new catalyst-specific colloidal silica products in response to customer needs, and strive to provide high-quality catalyst special silica sol products for catalyst industry partners to assist customers in solving catalyst-related technical problems.
