AB  - In this work, the coefficient of fluid-wall mass transfer in an inverse fluidized bed was determined using the adsorption method. The experiments were carried out in a column with a diameter of 45 mm with spherical and non-spherical particles of polypropylene and polyethylene with a diameter of 3.3-4.9 mm and a density of about 930 kg m-3. A diluted solution of methylene blue was used as a fluidization medium, which was adsorbed on part of the surface of the column on silica gel. The obtained results showed that the presence of particles during inverse fluidization does not contribute significantly to mass transfer compared to the influence of particles on transfer in conventional fluidized beds. Therefore, the pseudofluid concept was introduced into the analysis and an empirical correlation was performed to determine the mass transfer coefficient. The obtained results were compared with literature correlations for inverse and conventional fluidized beds.
AB  - У овом раду је одређиван коефицијент преноса масе флуид-зид у инверзнофлуидизованом слоју применом адсорпционе методе. Експерименти су вршени у колони  пречника 45 мм са сферичним и несферичним честицама полипропилена и полиетилена  пречника 3.3-4.9 мм и густине око 930 кг м-3. Као флуидизациони медијум коришћен је  разблажени раствор метиленски плавог који је адсорбован на делу површине колоне на  силикагелу. Добијени резултати показали су да присуство честица при инверзној  флуидизацији не доприноси значајно преносу масе у поређењу са утицајем честица на  пренос масе у конвенционално флуидизованим слојевима. Због тога је у анализу уведен  концепт псеудофлуида и изведена је емпиријска корелација за одређивање коефицијента  преноса масе. Извршено је поређење добијених резултата са литературним корелацијама за  инверзну и конвенционалну флуидизације.

AB  - To define the fluid-dynamic properties of inverse fluidized beds, studies of the minimum fluidization velocity and bed expansion were performed in this work. The experiments were performed in
an inverse fluidized bed of polypropylene and polystyrene particles in a cylindrical column using
water and an aqueous glycerol solution of different concentrations as fluidizing medium. The
dependence of the bed porosity on the superficial velocity of the fluid was determined experimentally for all the particles studied and different fluidizing media. The influence of fluidizing
medium viscosity and particle density on the expansion of the inverse fluidized bed and on the
minimum fluidization velocity was investigated. Comparison of the experimental data for the
expansion of the inverse fluidized bed and the values calculated by the Richardson-Zaki
correlation for the conventional fluidized bed showed some deviation, but the experimentally
determined data were found to follow the shape of the Richardson-Zaki curve. In this paper, a
correlation for the expansion of inverse fluidized beds is proposed

AB  - The movement of particles in the fluidized bed primarily determines the mixing in the bed and determines the transfer intensities that occur between the particles and the fluid. Experimental monitoring of the velocity of the marked particle was performed in an inversely fluidized bed of polypropylene, polyethylene, and polystyrene particles. The velocity of the marked particle was monitored in a two-dimensional column, where water and an aqueous solution of glycerin were used as the fluidization medium. Using the Tracker Video Analysis program (Tracker Video Analysis, Open Source Physics, 2003), the mean velocity of the marked particle was determined, as well as the distance crossed by the marked particle in the x and y directions. The influence of fluidization medium viscosity and particle density on the velocity of the marked particle was investigated. The results of experimental investigations have shown that the particle velocity distribution approximately follows the Maxwell distribution. Comparison of the measured values of the mean velocity in the inversely and conventionally fluidized bed showed a certain deviation. In this paper, a correlation for determining the mean particle velocity in an inversely fluidized bed is proposed.
