Investigation of liquid distribution in gas–solid fluidized beds for fluid cokers

open access: yesThe Canadian Journal of Chemical Engineering, Volume 103, Issue 8, Page 3983-3998, August 2025.
Abstract Thermal cracking processes convert larger molecules into smaller, more valuable products, without a catalyst, allowing for transforming residual oils or waste plastics into useful compounds. Fluid coking, a thermal cracking process utilizing a fluidized bed of hot particles, processes approximately 1 million barrels of residual oil daily. This
