PHTD catalyst

PHTD catalyst is produced by Pt and Pd as the active component and cordierite honeycomb as the carrier with the characteristics of high efficiency, stable performance and no acid odor.
Application :Purification of organic waste gases emitted from soft package printing. 
PHTD catalyst can be used normally for 1 year or constantly for 8,000 hours at space velocity of 12,500-15,000h-1 . with optimal operating temperature of  320-450 ℃, Max. use temperature of 550 ℃ and Max. expose temperature of 650 ℃. Concentration of VOCs can be 500-4,000 mg/m³.
