Multifunctional fluidized bed reactors for process intensification 2024 Access copy available to the general public Unrestricted Fluidized bed reactors (FBRs) are crucial in the chemical industry, serving essential roles in gasoline production, manufacturing materials, and waste treatment. However, traditional up-flow FBRs have limitations in applications where rapid kinetics, catalyst deactivation, sluggish mass/heat transfer processes, particle erosion or agglomeration (clustering) occur. This review investigates multifunctional FBRs that can function in multiple ways and intensify processes. These reactors can reduce reaction steps and costs, enhance heat and mass transfer, make processes more compact, couple different phenomena, improve energy efficiency, operate in extreme fluidized regimes, have augmented throughput, or solve problems inherited by traditional reactor configurations. They address constraints associated with conventional counterparts and contribute to favorable energy, fuels, and environmental footprints. These reactors can be classified as two-zone, vortex, and internal circulating FBRs, with each concept summarized, including their advantages, disadvantages, process applicability, intensification, visualization, and simulation work. This discussion also includes shared considerations for these reactor types, along with perspectives on future advancements and opportunities for enhancing their performance. info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 37.0 2024 ENERGY & FUELS 2 / 182 = 0.011 2024 Q1 T1 THERMODYNAMICS 1 / 79 = 0.013 2024 Q1 T1 ENGINEERING, MECHANICAL 1 / 182 = 0.005 2024 Q1 T1 ENGINEERING, CHEMICAL 1 / 176 = 0.006 2024 Q1 T1 8.031 2024 Chemical Engineering (miscellaneous) 2024 Q1 Fuel Technology 2024 Q1 Energy Engineering and Power Technology 2024 Q1 73.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Kulkarni, S.R.
