Production of hydrogen and carbon nanotubes from methane decomposition in a two-stage fluidized bed reactor
TL;DR: In this article, a two-stage fluidized bed reactor with Ni/Cu/Al 2 O 3 catalyst was used to decompose methane with high activity in the high temperature condition and then the carbon produced will diffuse effectively to form carbon nanotubes in both low and high temperature regions.

Stochastic models for transport in a fluidized bed
TL;DR: It turns out that discretization of the reactor into a moderate number of segments already gives excellent numerical approximations to the continuous model, and in the diffusion limit a partial differential equation for the particle density p(t,x) is obtained.

Hydrodynamic and solids residence time distribution in a binary bubbling fluidized bed: 3D computational study coupled with the structure-based drag model
TL;DR: In this paper, the simulation of bubbling fluidized beds (BFB) residence time distribution (RTD) based on the structure-based drag model is conducted for the single and binary gas-solid phases systems, a comparison of computed results with experimental data proves that their model is applicable to both systems with better accuracy.

A model for residence time distribution in multistage systems with cross-flow between active and dead regions
J. Raghuraman,Y.B.G. Varma +1 more
TL;DR: In this paper, a three-parameter mathematical model for expressing the residence time distribution in multistage systems is proposed, in which a fraction of the feed short-circuits each stage consists of an active backmix region and a dead region with cross-flow of the material between the two regions.

Pressure drop of the fluid and the flow patterns of the phases in multistage fluidisation
TL;DR: In this paper, the authors discussed the theoretical models, experimental data and the range of applicability along with the correlations to predict the characteristics of the bed and discussed the correlations with respect to the theoretical model and experimental data.

An experimental investigation of the residence time distribution of solids in multistage fluidisation
J. Raghuraman,Y.B.G. Varma +1 more
TL;DR: In this paper, the cross-flow model was matched with the experimental data taken subsequently on the residence time distribution of solids in a multistage fluidised bed, and conditions for smooth fluidisation were suggested.
