Gas residence time testing and model fitting : a study of gas-solids contacting in fluidised beds.
This work is concerned with the effect of vessel geometry on the hydrodynamics of fluidisation of a bed of milled iron oxide. The effect of going from a cold model representative of a typical pilot plant reactor to one ...
Comparison between air drying and steam drying in a fluidized bed.

Reflux classification of South African coal.
In mineral processing, the value of a particle is inexorably related to its specific gravity (Galvin et al., 2009). As a result, gravity concentration is widely employed in the beneficiation of valuable minerals from the ...
The effect of particle properties on fluidized bed hydrodynamics and entrainment.
This study focuses on the effect that particle properties (size, density and shape) have on fluidized bed hydrodynamics and entrainment rate. The experimental work was carried out using two Plexiglas columns having ...
Time-series analysis of pressure fluctuation in gas-solid fluidized beds.
Fluidized beds have been used extensively in chemical process industries for several years. The success of fluidized operations is largely dependent on a well-defined and stable contact regime. Hence, the ability to ...
Fluidization and sedimentation behaviors of nanoparticles.
A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 to 100 nanometers in diameter. Nanoparticles were used by artisans since prehistoric times, albeit without knowledge of their ...
Zonal separation and solids circulation in a draft tube fluidized bed applied to coal gasification.
In this thesis a fluidized bed containing a draft tube has been studied with the aim of developing the apparatus for coal gasification. The process has the capability of producing synthesis quality gas using air for ...
