Why does the catalyst in a converter overheat when exposed to high oxygen levels?
Catalyst desulfurization releases a large amount of heat.
The catalyst reacts with oxygen, releasing a large amount of heat
CO, H2, and O2 react, releasing a large amount of heat
Not only can it cause overheating, but it can also form explosive mixtures with gas, and react with alkali metals in catalysts to produce sulfates, thereby deactivating them. For every 0.1% increase in oxygen content in the gas, the furnace temperature rises by more than 8 degrees
Oxidation reaction: it reacts with the alkali metals in the catalyst to form sulfates, releasing a large amount of heat
