Yield of products from diesel hydrogenation with different raw material ratios
Thread Content
In a diesel hydrorefining unit, where the feedstock is a mixture of straight-run diesel and catalyzed diesel, under the same operating conditions and parameters, how does the varying ratio of straight-run diesel to catalyzed diesel affect the yields of refined diesel and crude gasoline?
Is there anyone who can help analyze this?
In my opinion, an increase in the straight-chain to paraffin ratio will reduce the yield of crude gasoline.
Because pressing the firewood makes it more likely to crack, right?
I have a gentle question: in diesel hydroprocessing, if it involves only refining agents, then the only effects are reduced density (desulfurization, aromatics saturation), right? The yield shouldn’t change, does it? And for diesel hydroprocessing, it seems to depend on factors like the desulfurization rate; in the case of hydroprocessing-induced degradation, then the yield needs to be considered
It’s like this: our plant has one unit for hydroprocessing and another for refining. In hydroprocessing, the focus is on the yield of diesel; when the proportion of straight-run diesel is high, the yield of refined diesel decreases, as straight-run diesel causes a large amount of crude gasoline to be cracked. As for refining, the yield of refined diesel is always around 98.5%. However, I’ve noticed that depending on the ratio of straight-run diesel to catalyzed diesel in the refining feedstock, the yield can vary sometimes being higher and sometimes lower. I’m not quite sure why Seeking advice
