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.
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.
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.
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.
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.
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).
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.
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.
In some Barracuda Virtual Reactor simulations, it is useful to dynamically and automatically control flow rates, pressures, temperature, or other parameters at boundary conditions (BCs) based on information from data…
Despite more than 100 years of commercialization of wide-ranging fluidized bed reactors, scale-up tools and methods have remained quite similar. To exploit the benefits of fluidized beds for the time-critical sustainability challenges, scale-up has to be implemented quicker and better.
