What is the effect of oxygen on methanol catalysts? In a methanol plant using coke oven gas, the oxygen content in the gas entering the synthesis tower was 0.91%, while it was 0.97% in the gas exiting the tower. What is the effect of oxygen on methanol catalysts?
Your analysis can’t be correct; there should be no oxygen at the outlet of the synthesis tower – it’s likely to be argon (chromatography cannot distinguish between oxygen and argon). Oxygen would rapidly oxidize the copper catalyst, and then it would be reduced by the reducing gases, affecting both the conversion rate and the catalyst’s service life
The oxygen content at the inlet is also high? That can’t be right
