Is the ash in delayed coking coke mainly catalyst?

Is the ash in delayed coking coke mainly catalyst? Is catalytic slurry the main component used in coking residue? Is the ash in coke a catalyst? Are there any other influencing factors?
There are also metal compounds and salts in the oil
If reused waste oil is also blended in, there are even more factors that can affect the ash content; catalysts, metal compounds, and salts such as calcium, magnesium, and sodium can all contribute to this
It should mainly be the carbon after the reaction and the catalyst, followed by salts
It depends on the properties of the raw materials; for normal raw materials, slag reduction is used, while the factor affecting ash content is salt content. If some catalytic slurry is blended in, the ash content is related to the catalyst dust content.
Ash: The non-combustible residual impurities left over after all the combustible parts of petroleum coke have been completely burned at a temperature of 850 degrees Celsius plus or minus 25 degrees Celsius, in the presence of airflow
