Catalytic overcracking
Thread Content
In FCC: the oil-to-catalyst ratio leads to excessive cracking, and the reaction temperature also causes excessive cracking; those data can be used to tell that How can one determine what is the best option? What factors should be considered? I hope to receive guidance from all the teachers! Thank you!
Personally, I think it still depends on the product yield
Let’s take a look at the product distribution. If the dry gas production is too high, it’s excessive.
After passing the cracking point, the yields of dry gas and coke increase significantly, while gasoline production decreases and the yield of liquefied gas increases at a constant rate;
Look at the yields of dry gas, coke, and dry gas + coke; additionally, the dienes in the pyrolysis gas (enriched gas) are increasing~~~
