Catalytic equilibrator
Thread Content
I forgot what MA, PV, and SA mean in catalytic balancers – what are the values for each of these parameters?
MA: Microreactivity; generally, it should be above 60.0 for heavy oil catalytic cracking； PV: Pore volume, which depends on the properties of the oil used in the device; if there is no severe metal contamination, it can be around 0.34. For oils with poorer quality in China, the pore volume is usually around 0.30 ； SA: Specific surface area. Generally, for heavy oil catalytic cracking, it is above 100; in units where metal contamination is not severe, the specific surface area can be around 120.
