2021, Journal of Analytical and Applied PyrolysisCitation Excerpt :In this work, the pyrolysis temperatures were controlled as accurately as possible. In classical FBs the axial and radial temperature differences typically exceed 15 K [35] in addition to local temperature differences due to the presence of gas bubbles [36]. Fig. 3 shows the temperature during the first fifteen minutes and the last ten minutes of a typical one-hour length experiment in the GSVR.
Cost-effective clean ammonia production using membrane-assisted autothermal reforming
2021, Chemical Engineering JournalCitation Excerpt :The MA-ATR reactor (Fig. 1) was modelled in ANSYS Fluent almost identically to the methodology reported in the previous work of the authors where the MA-ATR concept was presented for hydrogen production [16]. This model includes reaction rate expressions for the reforming [23,24] and oxygen carrier redox [25] reactions, permeation of hydrogen through the membranes [26], axial dispersion of solids species and heat [27], as well as additional modelling to account for momentum [28] and mass [29] transfer limitations caused by the mesoscale structures (bubbles) formed in the fluidized bed reactor. The equation system is outlined in the appendix of Wassie et al. [30] for more details.
A novel experimental method for determining lateral mixing of solids in fluidized beds – Quantification of the splash-zone contribution
2020, Powder TechnologyCitation Excerpt :Indirect methods do not provide dynamic trajectory or data of individual particles but typically interpret the solids as a continuum. Some examples of this from the literature include the monitoring of the concentration of an injected mass of tracer solids with specific magnetic [25], chemical [3,32], or temperature [2,7,33] characteristics. Mainly due to the high solids-to-gas density ratio, the contribution of the gas mixing to the effective thermal conductivity is negligible compared to the contribution of the solids mixing.
