VULCAN Series catalyst to remove O2 from H2 containing streams
• VIG-T02 and VIG-T03
– Noble metals based catalyst
– Cost effective
– Robust in reducing environments – trace O2 from H2 containing streams is
ideal
• Light duties
• Useful for O2 removal at ~30°C
Heat of reaction dH = -242 kJ/Mol
– O2 content should not exceed 2%
– H2 content should not exceed 4%
• Inlet temperature should be > 5 oC above gas dew point since condensed water causes catalyst inhibition
• VIG-TH1
– Noble metals based catalyst
– Robust
in oxygen containing environments – trace H2 from O2 containing streams is ideal
– Hydrogen removal from CO2 (Dehydrogenation Catalyst)
VULCAN Series catalyst to remove H2 from O2 containing streams
• VIG-TH2 and
VIG-TH3
– Noble metals based catalyst
– VIG-TH2 and
VIG-TH3 are used in CO2 feedstocks to urea plants to remove H2, VIG-TH2 usually is used in natural gas based urea plants, VIG-TH3
usually is used in coal or residue oil based urea plants, market share approx. 60% in China.
– Robust in oxygen containing environments – trace H2 from O2 containing streams is ideal
• Light duties
• Useful for O2 removal at ~30°C
• Heat of reaction dH = -242 KJ/Mol….
– O2 content should not exceed 3%
– H2 content should not exceed 6%
• Inlet temperature should be > 15 oC above gas dew point since condensed water causes catalyst inhibition
