Large scale production of multi-walled carbon nanotubes by fluidized bed catalytic chemical vapor deposition : a parametric study [PDF]
, 2007 A parametric study investigating the impact of temperature, run duration, total pressure, and composition of the gaseous phase on the catalytic growth of multi-walled carbon nanotubes (MWNT) has been performed. MWNT have been produced very selectively on

Coherent structures and bubble-particle velocity in 2-D fluidized beds [PDF]
, 2008 This work presents an experimental study to characterize ascending bubbles and granular velocity in the dense phase of a 2-D fluidized bed. Three different non-intrusive techniques based on images obtained with a high speed camera are developed, and ...

The Coalescence of Bubbles in a Gas-solid Fluidized Bed
Chemical engineering, 1967 気泡会合の挙動を明らかにするため, 2つの気泡が2次元流動層内に存在する際の会合の研究を行なった。2つの気泡の相対的位置が麓々異なる場合, あるいは2つの気泡径比が種々の場合の気泡の上昇速度の変化, path line会合に要する時間を調べた。そして著者らの得た気泡会合のモデルと比較し, 実験結果がそのモデルでかなりよく説男できることを知った。

Selective hydrogenation in trickle-bed reactor. Experimental and modelling including partial wetting. [PDF]
, 2003 A steady state model of a trickle bed reactor is developed for the consecutive hydrogenation of 1,5,9-cyclododecatriene on a Pd/Al2O3 catalyst. Various experiments have shown that the selectivity of this reaction towards the product of interest is much ...

Separation Experiments in Gas–Solid Fluidized Bed Using Geldart a Dense Medium
SeparationsGas–solid fluidized bed separation uses upward gas flow to fluidize a dense medium. By controlling medium properties, gas velocity, and bed height, the apparent bed density can be adjusted so that low-density particles float and high-density particles ...
