PRODUCT & SERVICE

CATALYSTS

A diverse product line featuring catalysts to support environmental remediation and catalysts used in essential daily items.

De-NOx catalysts and de-DXN catalysts break down nitrogen oxides and dioxin generated by thermal power plants and waste incineration facilities. Hydrogenation catalysts (nickel/copper catalysts) are used to produce raw materials used in shampoo, adhesives, and optical films. Polyester polymerization catalysts are used to produce raw materials used in polyester fibers, PET bottles, and PET films.

PRODUCT LIST

De-NOx Catalysts/ De-DXN Catalysts

■Overview

De-NOx catalysts reduce and eliminate nitrogen oxide generated by power plants and waste incineration. De-DXNs catalysts break down and eliminate dioxins generated by waste incineration. Both of these can assist with environmental remediation, and they are expected to gain increasing attention in the near future. We have established advanced formulation technologies that optimize the interactions between titanium dioxide, active metals, and forming additives to achieve the ideal catalyst quality. In addition, through years of refinement, we have developed production processes that maximize performance while ensuring excellent formability. We are confident that we have products to match every need of our clients, and we welcome new inquiries.

Stabilized Nickel Catalysts (SN series)

Features and Applications

Features Applications
Stabilized Nickel Catalyst is produced by drying, reducing, and stabilizing nickel salt from purified diatomaceous earth. It is commonly used for its hydrogenation effects on organic compounds, and features strong hydrogenation activity and high selectivity.
  1. Partial or full hardening of fats/oils
  2. Nuclear hydrogenation of benzene
  3. Hydrogenation of C-C double bonds and triple bonds
  4. Hydrogenation of resin
  5. Hydrogenation of other general organic compounds and liquids

Grade

Grade Features
SN-250 High nickel content with excellent poison resistance and low-temperature activity. Used for various hydrogenation effects of fats/oils. Sharp particle distribution and excellent filterability.
SN-750 Improved version of N-250 grade with high specific surface area, and high hydrogenation actitivy and selectivity. Sharp particle distribution and particularily excellent filterability after responses. Boosts efficiency of processes with repeated use.
SN-780 Premium grade with highest nickel content and specific surface area. Used for hydrogenation at high temperatures and pressures. Ideal for hydrogenation of aromatic petroleum resins.
