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 margarine, 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. Sakai Chemical Industry manufactures titanium dioxide, the primary raw ingredient of these catalysts. We are the only company in the world with the integrated technology capable of covering every stage from raw materials until final products like catalysts. We are confident that we have products to match every need of our clients, and we welcome new inquiries.
