Regarding the feed properties of cracking units, what are the main factors that affect yield? The feeds typically include coker wax oil, atmospheric wax oil, fuel oil, etc. In terms of properties such as sulfur content, specific gravity, and basic nitrogen, which of these feed properties influence yield (for gasoline, diesel, liquefied gas, slurry oil, etc.)?
The UOP K value can simply indicate the level of light ends recovery.
The key point is that specific gravity affects the yield.
Regarding raw materials, the key factors are residual carbon, sulfur content, nitrogen content, and heavy metals – all of these affect the activity of the catalyst. Residual carbon influences the amount that can be processed, while the amount of residue oil added also affects the composition of the product. The heavier the raw materials, the less gasoline and liquefied gas will be produced, and more oil slurry will result
