How is catalytic slurry purified?
Thread Content
Currently, catalytic cracking slurry has a relatively high solid content, as well as a high level of heavy metals. How to reduce the metal content in oil slurry and residue to a specified range? (ICP testing: sodium ≯50, aluminum + silicon ≯50, vanadium ≯150, calcium ≯30, zinc ≯15, phosphorus ≯15)
There was originally a set of equipment for magnetic separation of catalysts; it’s not clear whether it was effective or not. Essentially, to control the level of heavy metals, it is still necessary to properly adjust the parameters of electrodesalination.

There are no effective ways to reduce the levels of other metals in catalytic devices; alternative solutions include: 1. Hydrogenation of the catalytic material, 2. Extraction of the oil slurry via solvent deasphalting.
Not practical! This problem should be addressed starting with the raw materials!
