Abstract Removal of C 2 H 4 in the air was carried out continuous flow reactor with photocatalytic bed (expanded polystyrene spheres coated by TiO or SiO /TiO ) under irradiation UV light. Continuous a gas stream through realised at static and fluidization. The required for fluidisation 500–700 ml/min, whereas rate 20 ml/min used. Fluidized appeared to be much more efficient ethylene removal th...

Introduction Understanding the jetting phenomena near the gas distributor plate in a fluidized bed is important to gassolids mixing, heat and mass transfer, and erosion on any bed internals, which can all affect the performance of the bed. Moreover, acoustic vibration in a fluidized bed can be used to enhance the fluidization quality of particulate matter. Visualizing the jetting structure usin...

several methods are used to decrease seed drying time and enhance the quality of dried seeds. influidization methods, good aeration occurs during the drying process. in this research, conditioned seedswith 20% d.b. moisture content were dried at 30°, 40°, 50° and 60°c using three bed conditions (fixed,minimum fluidized, fluidized). all experiments were done using a batch-type fluidized bed drye...

Propylene is one type of plastic that is widely used in our everyday life. This study focuses on the identification and justification of the optimum process parameters for polypropylene production in a novel pilot plant based fluidized bed reactor. This first-of-its-kind statistical modeling with experimental validation for the process parameters of polypropylene production was conducted by app...

we evaluated the efficacy of a full-scale combined biophysicochemical system for treatingmolasses-based bioethanol wastewater in terms of organic substances, nutrient, and dark brown color removal. the main organic removal unit, i.e., the upflow anaerobic sludge blanket (uasb) reactor, achieved 80.7% removal and 4.3 nm3 methane production per cubic meter of wastewater with a hydraulic retention...

In the present study, dry reforming of methane (DRM) has been simulated in fluidized-bed reactors using multiphase particle-in-cell model. The model was meticulously built to investigate effect a wide range superficial gas velocities covering particulate, aggregative, and lean-phase flow regimes on bed hydrodynamics, conversion, yields product gases. Constant values for catalyst loading, CH 4 :...

In the first part (Part I) of this study, a novel fluidized bed reactor was modeled mathematically for methanol synthesis in the presence of in-situ water adsorbent named Sorption Enhanced Fluidized-bed Reactor (SE-FMR) is modeled, mathematically. Here, the non-dominated sorting genetic algorithm-II (NSGA-II) is applied for multi-objective optimization of this configuration. Inlet temperature o...

Spirals as internals are utilized to reduce the axial mixing of solids in fluidized beds, by routing the solids flow in a predetermined route or by localizing the solids mixing. The drying kinetics of continuous fluidized bed with and without internals has been compared and modeled using batch drying kinetics and residence time distribution analysis. The batch drying experiments were conducted ...
