This book presents the current carbonaceous fuel conversion technologies based on
chemical looping concepts in the context of traditional or conventional technologies. The key …

Abstract Design and scale-up of fluid catalytic cracking (FCC) riser is still largely empirical,
owing to limited understanding of inherent multiphase flow in this equipment. The …

The activity for the reduction of NO with CO, selectivity to N 2 and the catalytic stability in the
presence of O 2, water steam and SO 2 of Cu (II) or Fe (III) oxide catalysts supported on …

Both experimental and computational studies of the fluidization of high-density polyethylene
(HDPE) particles in a small-scale full-loop circulating fluidized bed (CFB) are conducted …

Influences of configurations of solids feeding device and riser exit on the flow behaviors of
gas–solid in a solids circulation system were studied in order to investigate a highly dense …

A loop seal is used to control a solid circulation rate and loop seal aeration ratios at the
supply and recycle chambers are another factor that affects its efficiency and circulating …

The hydrodynamic characteristics in the bottom region of circulating fluidized bed (CFB)
risers with fluid catalytic cracking (FCC) particles were studied over a wide range of …

It has been widely recognized that the exit geometry of circulating fluidized bed (CFB) risers
may have significant effects on the hydrodynamics of gas–solid flow. However, a …

The understanding of gas–solid flow is of great importance for various high-density
circulating fluidized bed (HDCFB) practices. In this work, the effects of exit geometry on the …

Effects of the inlet and outlet position on flow patterns of saturated fluids in a horizontal
subsurface-flow constructed wetland were investigated experimentally using a quasi two …
