Catalytic cracking balancing agent analysis table
Thread Content
Teachers, please ask: MA(m%), PV(ml/g), SA(m squared/g), ABD(g/ml), 0-20U(m%), 0-40U(m%), 0-80U(m%), 0-105U(m%), 0149(m%), APS(m) in the catalytic cracking balancing agent analysis table What are they referring to? How to analyze these data? Thank you.
MA refers to the catalyst activity. The system catalyst activity is generally required to be maintained above 60. PV refers to the pore volume of the catalyst. The equilibrium catalyst is generally above 0.3. SA refers to the specific surface area, which is required to be above 100. ABD is the ZUI density, APS is the average particle size, and the others are particle size distribution.
Thank you for your help, thank you!!!11111
The equilibrium activity is used to evaluate the catalytic performance of the catalyst. If it is low, it indicates the existence of hydrothermal deactivation or heavy metal poisoning or coke deposition. The pore volume can determine the catalyst's selectivity for cracking oil products. Catalysts with large pores have stronger ability to crack heavy oil. Density and particle size can not only evaluate the fluidization performance of the catalyst, but also the anti-wear performance of the catalyst. The rotational separation working conditions can also be judged from the particle size distribution. If there are too many fine powders, there may be thermal collapse of the catalyst. If there are too few fine powders, the rotational separation working conditions have deteriorated, which is usually accompanied by the phenomenon of agent running.
