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.
Solar-driven biomass steam gasification by new concept of solar particles heat carrier with CPFD simulation
This paper, which uses Barracuda Virtual Reactor simulation results, demonstrates that solar-driven biomass gasification, using solar-heated particles as a heat carrier and a fluidized bed reactor, enhances green H2-enriched syngas production by improving heat transfer and gasification kinetics, thereby enabling continuous and stable operation despite fluctuating solar flux.
Computational fluid dynamics study of the dry reforming of methane over Ni/Al2O3 catalyst in a membrane reactor. Coke deposition
This work investigates the dry reforming of CH4 as an important process for the conversion of greenhouse gases to synthesis gas. The paper is an attempt to numerically analyse by computational fluid dynamics (CFD) the coking and gasification mechanisms in the lab-scale membrane module with a fixed-bed supported nickel catalyst (Ni/Al2O3).
Dry reforming of biogas in fluidized bed: Process intensification
This work combines a catalytic reaction, a separation and the catalyst regeneration in a single reactor. To this end, a two zone fluidized bed reactor with hydrogen selective membranes has been employed.
Modelling of methane dry reforming over Ni/Al2O3 catalyst in a fixed-bed catalytic reactor
The dry reforming of CH4 in a fixed-bed catalytic reactor for the production of hydrogen at different temperatures over supported Ni catalyst is studied in this paper.
