Effect of reaction temperature on coking amount
Thread Content
How can it be explained that within a certain range of reaction temperatures, an increase in reaction temperature leads to a decrease in coking?
How did you observe a decrease in the amount of coke formed? Theoretically, increasing the reaction temperature, raising the catalyst circulation rate, and increasing the catalyst-to-oil ratio should lead to an increase in the reaction depth, which in turn should result in an increase in the amount of coke formed
It’s not clear whether you are referring to coking or catalytic coke formation; the effect of temperature on coke formation in these two processes is completely different.
