The catalytic yield decreases
Thread Content
A new type of catalytic material has been recently introduced, and the yield of light products (gasoline, diesel, liquefied gas) has dropped from 82% to 79%, while the overall yield (gasoline, diesel, liquefied gas, oil slurry) has fallen from 86% to 83%. The yields of dry gas and coke have remained relatively unchanged; in other words, 3-4% of the yield seems to have disappeared. Measurements have shown no issues, so I would appreciate it if experts could help analyze this from a technical perspective
Is the raw material sourced from externally purchased catalytic materials? If it comes through legitimate channels and is originally a regular depressurized feed for catalysis, it shouldn’t be like this. In some oil blending processes, the additives that are added end up disappearing and cannot be found; there is an imbalance between the raw materials used and the yield obtained
What a strange thing; have you found the reason?
