Abstract

During CeO2 preparation via jet-flow pyrolysis, the standard spherical particles typically assumed in numerical simulations do not match the actual particle morphologies. In the present work, an extension factor α, fullness factor k, and shrinkage ratio β were introduced to characterize the distributions of several specific types of irregular spherical CeO2 particles inside a jet-flow pyrolysis reactor. All three parameters were found to affect the CeO2 yield, with the maximum yield of 98.73% obtained at α = – 0.25, k = 1 and β = 1 and a lower yield of 92.05% at α = 0.25, k = 1, and β = 1.5.
