Measurement of solid content in FCC external slurry
Thread Content
As the title suggests, how does a laboratory measure the solid particle (catalyst) content in catalytically treated slurry? What are the main methods available at present? I would like to ask everyone for advice.
Thank you for the answer. I would like to ask about the error levels of these two methods
Most companies use the centrifugation method. Is the ash method a type of combustion method? The errors from these two methods aren’t that large; as long as one method is used consistently, patterns can still be observed in the variations
Centrifugation is used for routine rapid testing. If calibration or assessment uses the analytical method GB/T511 for machine impurities. The method for analyzing ash involves burning all the organic matter; the resulting value is low and not very representative.
