Relationship between catalytic processing volume and coke formation amount
Thread Content
Does a low catalytic processing volume lead to high coke formation? Why is that?
There is a certain relationship, but it’s not significant; the residue carbon in the raw materials is the most crucial factor. Of course, there are other conditions and factors that affect coking.
There are many reasons that lead to coke formation, and these need to be considered comprehensively. Is the content of asphaltenes and resins in the raw material too high? Too low a reaction temperature leads to the formation of soft coke and reduced catalyst activity
What you might mean is the relationship between the oil-to-agent ratio and coke formation.
1 The steam used for atomizing the raw materials should not be reduced; on the contrary, it needs to be increased appropriately to ensure proper atomization by the nozzle. A too high oil-to-slurry ratio can also lead to an increased coke yield. 3 A long reaction time leads to an increased coke yield.
Oh, I’m sorry; I meant to talk about coking issues. Could coking occur significantly in the settler and at the oil and gas inlet?

In sedimentators, coking also occurs at the inlet of large oil and gas pipelines. The degree of coking in sedimentators depends mainly on the residence time of the oil and gas within them; a longer residence time leads to more significant coking. In addition, it will be considered whether there is corresponding anti-fogging steam. Coking at the inlet of large oil and gas pipelines mainly depends on the flow velocity of the oil and gas within the pipelines; coking becomes significant when the flow velocity is too low. Furthermore, it is also directly related to the hot and cold walls of large oil and gas pipelines. In summary, the factors affecting catalytic coking vary depending on the location where coking occurs; it is not caused by a single factor, as coking is a result of multiple interrelated factors
With all conditions remaining unchanged, an increase in the processing volume will also lead to an increase in the amount of raw coke produced. However, under normal circumstances, the daily processing volume is already at the designed level, so it’s not possible for it to increase significantly. However, in contrast, an increase in the properties of the feed has a greater impact on the amount of coke formed.
