1. Introduction. Slurry bubble column reactors (SBCRs) are multitubular columns, operating with gas-liquid-solid systems mostly under isothermal conditions as the heat of reaction is removed through carefully designed cooling tubes or pipes with a large surface area for heat transfer [1, 2].The power needed for mixing and suspending the solid (catalyst) in SBCRs is primarily provided by …
