Any vessel in which solids are transported upward by a gas stream and then recycled to the
bottom may be classified as a Circulating Fluidized Bed (CFB). We describe possible CFB …

The objective of this paper is to review experimental and theoretical studies of gas-solid
fluidization at elevated temperatures and pressures. The survey begins with the low velocity …

Over the past decade, the prospect of climate change resulting from anthropogenic CO2 has
become a matter of growing public concern. Not only is the reduction of CO2 emissions …

Flow behaviour of fluid catalytic cracking particles were investigated in a riser with
volumetric solids concentrations of 20% and more. The air velocity and solids circulation flux …

A predictive mathematical model, able to characterize and quantify all facets of the time-
averaged gas and solids flow structure and properties within circulating fluidized bed (CFB) …

Probabilistic averaging is used to model fluidized‐bed reactors across the three fluidlization
flow regimes most commonly encountered in industry (bubbling, turbulent, and fast …

Fluidized catalytic cracking (FCC) is regarded one of the most significant operations in the
oil refining industries to convert feedstock (mainly vacuum gasoil) to valuable products …

Ž. Fluidized catalytic cracking FCC units have been considered the most successful
application of circulating fluidized Ž. beds CFB in the past decades. The total worldwide …

The hydrodynamics of a circulating fluidized bed (CFB) were studied using radioactive
argon as a tracer. The impulse experiments show that gas passes through the riser at …

Methanol is obtained commercially from natural gas. However, production of light olefins
such as ethylene, propylene, etc. from natural gas is higher value-added gas conversion …
