CO,HC,and NOx go through purifier made of multi-hole cordierite catalyst honeycomb carrier, it make the gases more active and do oxide-reducing chemical reaction. CO is oxidized into no color and no poison CO2 under high temperature. HC chemical compound is oxidized into H2O and CO2. NOx is restored into nitrogen gas. The poisonous gases are made into unpoisonous gas to make them pure. JINTAI ceramic honeycomb series including: Heat Transfer Media for RTO,Catalyst Support Monolith For RCO, Auto and Motor Catalyst Support, Electrical Blower Ceramic Slice, Infrared Honeycomb Ceramic Plate and Liquefied Gas Stove Slice
