Investigation and Analysis of Fe۲O۳ Catalytic Desulphurization within a Magnetically Fluidized Bed

To achieve the efficiency of flue gas desulphurization, a new method of a magnetized fluidized bed (FGD-MFB) was tested experimentally to obtain the enhanced effectiveness of the method. This process mixes magnetic particles with an external magnetic field to enhance catalytic activity and reaction kinetics. Characterization methods such as XRD, SEM, and EDAX supported the contribution of the catalytic effect of Fe۲O۳. A strong ۴۰ mT magnetic field also played a significant role in enhancing desulphurization performances to ۸۵.۹۳ % as a maximum within an optimum environment where the particle size was ۲۲۰ µm, and the flue gases reached a temperature of ۲۵۰ oC. Removal of the magnetic field, on the contrary, decreased efficiency to ۵۷.۹۶ %. The catalytic action of Fe۲O۳ as an active center is improved by providing a lower activation energy and enhancing magnetic fields through surface porosity, micropore arrangement, and gas diffusion characteristics. The characterization study revealed the intensified production of calcium sulfate and sulfite on the particle surfaces due to the catalytic function of Fe۲O۳ in the reaction kinetics. This paper proves that in industrial desulphurization, magnetically assisted fluidized beds are a substantial and sustainable technology, but can be further optimized and put to broader use.
