The equilibrium agent in the catalytic unit when there is no feed has better fluidity, at the same operating pressure, compared to the green catalyst after feeding.
Under the same operating conditions, the fluidity of the balancing agent is better than that of the raw agent. The catalyst surface of the unreacted catalyst contains carbon deposits, resulting in a higher particle size and viscosity compared to that of the equilibrating agent; therefore, under the same operating conditions, the fluidity of the equilibrating agent is better than that of the unreacted catalyst
The balance agent has good fluidity; carbon deposition on the surface of the green body affects its fluidity
The fluidization in catalytic cracking is a gas-solid fluidization, and the quality of this fluidization depends on the content of fine particles in the catalyst (generally referring to the proportion of catalyst particles with a size of 0-20 um); these particles play a role similar to that of solid lubricants in the fluidization process of catalytic cracking! It’s essential, but not in excessive amounts; otherwise, too much catalyst will be used! A balanced catalyst is a catalyst that has been regenerated, while an unbalanced catalyst refers to one that has undergone stripping followed by coking treatment; the former contains no more than 0.1% carbon, whereas the latter contains un-coked hydrocarbon components. Unfortunately, I cannot find at the moment the data related to the three types of catalysts used during our initial calibration, otherwise we could compare the figures and determine everything right away!
The catalyst in its raw state has better fluidity, as the oil and gas play a role in lubrication; this is also why poor catalyst flow tends to occur in the regeneration inclined tubes rather than in those of the raw catalyst.
Personally, I feel that the balance agent has better fluidity, while the raw agent is more viscous due to carbon deposits
The green catalyst has better fluidity, and its temperature is higher than that of the equilibrator! ! !
