What are the reasons for the high CO content in the ethylene cracking reaction?
The sulfur content in the raw material is low, or the methanol content in the raw material is high； Excessive cracking depth, severe coking, etc.
The high CO content is due to the reaction between water vapor and the coke on the furnace tubes; it seems that there is excessive coking.
It is guessed that the temperature is too high or the residence time is too long, resulting in excessive reaction depth.
