PHT catalyst

PHT catalyst is produced by Pt as the active component and cordierite honeycomb as the carrier with the characteristics of high activity, stable performance, strong anti-poisoning and long service life. The optimal operating temperature of the catalyst is 300-400 ℃. 
Application :Purification of organic waste gases (aromatic hydrocarbon, ester, ketone, styrene, isophorone, DBE, PMA ) emitted from various industries such as enameled wire, painting, metal printing, packaging and chemical process.
