Abstract
Experimental Study of the Effect of Catalyst Properties on Hydrodynamics and Mass Transfer in a Slurry Reactor
Highlights
One of the most alarms in global environmental problems today is the increase in the global temperature
They are typically applied to hydrogenation, chlorination, sulfonation–reaction, FisherTropsch synthesis or utilized as absorbers of environmental gaseous pollutants
The hydrodynamics in a gasliquid or gas-liquid-solid reactor are characterized by different flow regimes, mainly, the homogeneous transition, and heterogeneous regimes
Summary
One of the most alarms in global environmental problems today is the increase in the global temperature. The slurry bubble column is used in the chemical process industries as absorbers or reactors. Slurry bubble columns are used extensively in chemical industries for different processes. It is operated either in continuous or semibatch mode. Herbolzheimer and Enrique, 2006 reported that slurry bubble columns have many benefits over fixed bed column They have higher mass and heat transfer coefficients and as catalytic reactor, the catalysts used have higher service life. The hydrodynamics in a gasliquid or gas-liquid-solid reactor are characterized by different flow regimes, mainly, the homogeneous transition, and heterogeneous regimes. The dominate conditions that influence the hydrodynamics and mass and heat transfer behaviors include the superficial gas velocity, pressure, temperature, solid concentration and gas distribution. The hydrophobic/hydrophilic characteristic of solids is known to play a key role in many processes such as: wetting, flotation, enhanced oil recovery, cleaning technologies, supper-hydrophobicity, liquid spreading, etc
