Noble Metal Cat
TH-3 Urea Dehydrogen Catalyst
|
Application
TH-2/TH-3 are used in CO2 feedstock of urea plants to remove H2, TH-2 usually is used in natural gas based urea plants, TH-3 usually is used in coal or residue oil based urea plants, market share approx. 60% in China.
Characteristics
TH-2/TH-3 can ensure outlet H2 less than 50ppm of CO2 feedstock.
