FCC reagent consumption

Catalytic cracking – what is your reagent consumption now? How is it calculated? I hope to receive guidance from all the teachers!
To maintain the catalyst inventory and its activity, a small amount of catalyst must be continuously added during normal operation. The ratio of the amount of catalyst added to the feed rate is known as the catalyst consumption, expressed in kg per ton of raw material.
Our MIP process also uses more than 50 kilograms of catalyst per ton
What are the properties of your raw materials? The consumption of reagents is relatively low. What kind of raw materials are used?
Our calculation method is daily catalyst addition amount/processing volume. Our catalyst consumption ranges between 1.5 and 2.0, as the heavy metal content in our feed oil is relatively high, resulting in severe catalyst poisoning
Is this the crude oil that goes into the lift pipe for you? Do you mix in residue oil?
The specific catalyst consumption is generally 0.6–0.8 kg per ton of raw material; at a lower level it is 0.8–1.0 kg per ton of raw material, while at a higher level it is 0.4–0.6 kg per ton of raw material. This is an indicator generally used to measure the natural loss of catalyst efficiency. From the perspective of catalyst poisoning, it might be a bit higher; that is, in addition to the natural loss of catalyst, a portion of the balance agent also needs to be removed from the regenerator. This depends mainly on the balance of heavy metals, and to avoid excessive levels of heavy metals in the regenerated catalyst, this issue is addressed by removing such agents.
Is it atmospheric residue or vacuum residue that is blended in?
Is this data referring to the reagent consumption level of Sinopec companies? As far as I know, domestic refineries rarely manage to reach such a level
There are certain differences between newly installed devices and older ones, and there are also differences between large devices and small ones; large devices tend to have better performance in all aspects~~~
