Fluidization for Sustainability and Decarbonization Applications: The Parallel Evolving Roles of Processes and Computational Tools
This article examines the current trends in fluidization that have come about due to the newfound focus on sustainable applications, and how the role of computation tools used by those pursuing the applications is changing as well.
Insights in steam reforming of glycerol in a fluidized bed by CFD modeling
In this study, computational fluid dynamics (CFD) is used to investigate the performance of glycerol steam reforming in a fluidized bed system.
Methane steam reforming, methanation and water-gas shift: I. Intrinsic kinetics
In this paper, intrinsic rate equations were derived for the steam reforming of methane, accompanied by water-gas shift on a Ni/MgAl2O4 catalyst. A large number of detailed reaction mechanisms were considered
Glycerol steam reforming for hydrogen production: Traditional versus membrane reactor
A phenomenological model was developed for predicting the performance of a traditional reactor (TR) versus a membrane reactor (MR) for hydrogen production via glycerol steam reforming (GSR), which was validated against experimental data. The results were evaluated in terms of glycerol conversion and products yield and selectivity, and for the MR the hydrogen recovery was also accounted.
MP-PIC investigation of glycerol steam reforming in bubbling fluidized bed for high-quality hydrogen production
A reactive multiphase particle-in-cell approach is adopted to numerically investigate the physical and thermochemical characteristics of glycerol steam reforming process in a three-dimensional bubbling fluidized bed.
Sorption-Enhanced Reaction Process With Reactive Regeneration
A mathematical model taking into account multicomponent (six species) mass balances, overall mass balance, Ergun relation for the pressure drop, energy balance for the bed-volume element including the heat transfer to the column wall, and nonlinear adsorption equilibrium isotherm coupled with three main reactions was derived to model SESMR.
Determination of intrinsic rate constants of the CaO–CO2 reaction
The rate constant of the CaO–CO2 reaction was studied for two sorbents using an atmospheric thermogravimetric analyzer (ATGA) and a pressurized thermogravimetric analyzer (PTGA). A grain model was used to determine the rate-controlling steps.
A CPFD Simulation on Hydrodynamics of Carbon Nanotube Aggregates in a Fluidized Bed
This paper uses Barracuda Virtual Reactor to create a model of a fluidized bed reactor with carbon nanotube particles, which describes hydrodynamic behaviors such as bed expansion and solid holdup distribution.
