Factors affecting 95% catalytic diesel
Thread Content
Why is there such a large difference of 95% when the same reaction conditions and the same diesel extraction temperature are used to process different raw materials?
With different feedstocks, under the same conditions, the conversion rates vary, as does the degree of cracking. Feedstocks of paraffinic and naphthenic types require different levels of cracking effort, which is why the 95% content in diesel is not the same.
I still don’t fully understand it; could this sea friend explain it again?
Paraffin-based feedstocks require low reaction temperatures, achieve high conversion rates, and produce light diesel. Naphthenic-based feedstocks need higher reaction temperatures and greater activity, resulting in heavier diesel.
In simple terms, some feedstocks yield high rates of diesel, while others yield high rates of gasoline or liquefied gas.
Yes, not only is the diesel yield different, but the density and cetane number of the diesel also vary
The properties of the raw materials change rapidly; each purchase consists of different raw materials, and the quantity purchased in each instance is not large. That’s how local refineries work. Adjust promptly based on the test results. As long as the hydrogenation process meets the standards, that’s fine
