Catalytic dry gas
Thread Content
Where do the oxygen, nitrogen, carbon monoxide, and carbon dioxide in catalytic dry gas come from? ?
Raw materials and coked catalyst are carried along.
Oxygen is carried for sampling, and it will all be converted to nitrogen
What does it mean by \"contained in the raw materials\"? ?
Isn’t it a closed sampling method? ? Will oxygen get mixed in during sampling? ?
So the oxygen is carried there by the catalyst, right? ?
Insufficient catalyst degassing results in its remaining in the reaction products
Even if degassing is thorough, some will still end up in the dry gas, right? ?
This is normal; although there is a degassing setting, it cannot guarantee complete removal of gas, so it’s normal for dry gas to contain air – it’s just a matter of degree!
