Investigation on stripping effect of regeneration agent
Thread Content
What H/C value does the stripping effect have after stripping of the regeneration agent?
There is no need to limit the hydrogen-to-carbon ratio. Different raw materials will affect the stripping effect. The most important thing is to see the reaction of regeneration. Increase the amount first, then slowly reduce it until slight oiling occurs, then increase the amount of steam appropriately.
"Flying Catalytic Cracking Unit Technical Questions and Answers" states that if the hydrogen content in the catalyst coke reaches 5.9%, it indicates that the stripping effect is good.
