Precious metal catalyst is a precious metal material that can change the rate of chemical reactions without itself participating in the final product of the reaction. Almost all precious metals can be used as catalysts, but commonly used ar eplatinum, palladium, rhodium, silver, ruthenium, etc. Among them, platinum and rhodium are the most widely used.

It is non-toxic, odorless, non-flammable and non-explosive. It has a large surface area and is a high-performance adsorbent. It still has a high adsorption capacity when the adsorbate concentration is very low. It can selectively adsorb, dehydrate and dry, and dewax kerosene.

Molecular sieve activated powder is produced by subjecting molecular sieve synthetic raw powder to high-temperature dehydration. During the high-temperature calcination process, the molecular sieve raw powder loses most of its moisture, resulting in excellent dispersibility and rapid adsorption capacity. It exhibits good dispersibility and fast adsorption speed, making it suitable for certain specialized adsorption applications in industry, such as mixing and dispersing with materials for adsorption, or as an amorphous desiccant, among others.

Granular series activated carbon is made of high-quality coal, coconut shell and sawdust through a series of production processe black cylindrical particles are widely used in gas treatment,sewage treatment, desulfurization and denitration, solvent recovery and nitrogen generato-rair separation equipment,painting workshop and other fields in the purification of toxic gases, waste gas treatment,industrial and domestic water purificationtreatment and solvent recovery are also widely used.
