Catalytic raw material heavy metals
Thread Content
What are the optimal levels for the contents of basic nitrogen and heavy metals in the catalytic feed oil? Are there any specific numerical limits?
The lower this value, the better. Generally, the content of heavy metals, especially NI+V, should not exceed 30
The alkaline nitrogen content shall not exceed 800. The total metal content shall not exceed 25.
The lower, the better, definitely. Generally, the content of heavy metals, especially NI+V, should not exceed 30. What is the unit for this 30? :o
Are there any limitations for Fe, Ca, and Na?
Generally, the content of heavy metals, especially Ni and V, should not exceed 30 ppm, while the content of alkaline nitrogen should not exceed 800 ppm. Additionally, there are iron, calcium, and sodium
