Modelling of a bubble column slurry reactor for Fischer ...

hydrodynamics of a slurry bubble column reactor operating in the churn-turbulent regime is pictured in Fig. 1. The churn-turbulent regime of operation is the most optimal one for F–T synthesis [1]. One of the most important parameters to be estimated for slurry reactor design and scale-up is the holdup of gas bubbles in the reactor, .

fluidized bed reactor, and the bubble column reactor. A bubble column reactor is basically a cylindrical vessel with a gas distributor at the bottom. The gas is sparged in the form of bubbles into either a liquid phase or a liquid–solid suspension. These reactors are generally referred to as slurry bubble column reactors when a solid phase ...

Slurry - Visual Encyclopedia of Chemical Engineering

Slurry reactors are most frequently used when a liquid reactant must be contacted with a solid catalyst, and when a reaction has a high heat of reaction. They may be used in such applications as hydrogenation, oxidation, hydroformation, and ethynylation. The reactor shown below is a slurry phase hydrogenation reactor.
