The catalytic slurry has a high solid content and low ash content; the reason is

The tube bundles of the slurry steam generator are severely scaled, resulting in a short operating cycle. I’m asking experts to help analyze the reason.
Such a high solid content – does it mean there is a high catalyst content? Identify the reasons for catalyst loss and take action to address them
Let’s see what the level is after treatment with trichloromethane; the properties of the oil slurry might deteriorate, and we need to know what the yield will be
Slurry density: 1.06, yield: 3.5%
I asked the laboratory about the process used to determine the solid content in oil slurry – is gasoline used for dissolution followed by suction filtration? Could it be that the solvent isn’t suitable?
Ash content is determined using the combustion method, while the solid content is generally measured by centrifugation. It’s normal for there to be differences due to the different methods used. Ash content can provide a relatively accurate indication of the solid content in the oil slurry. However, if your solid content is 30 mg/l higher, could it be that the unit is incorrect? After converting this to the second floor, your solid content will be 0.03 g/L, which is well below the standards and requirements. Besides, your unit for ash content is incorrect; it’s more straightforward to express the ash remaining after burning in terms of volume. Your value of 0.2 mg/L actually corresponds to 0.2 ppm, so it seems that the data is incorrect
