Numerical investigation of the granule size effect on the reaction product yield in a catalyst fixed bed

Abstract

The research work presents the results of mathematical modeling of the ethylbenzene dehydrogenation process to styrene in a fixed catalyst bed. Calculations for the different length granule packaging are carried out. Calculated values of the reaction product yield (styrene) are in a wide range of gas velocities. There are significant differences in the yield of the product at high gas velocities for catalyst granules of different shapes. Of the considered catalyst granules forms, we got the best yield efficiency by the use of granules, which provide maximum surface area and porosity in the fixed bed catalyst.

Evaluation of the effective porosity of an open cell foam material for using in heat and mass transfer numerical simulations

“…Simultaneously, the porous structure's continuity makes it possible to remove or supply heat in a gaseous medium effectively. At the same time, the large surface area in combination with low resistance makes it possible to use OCF as catalysts for processes with wall surface reactions [9][10][11][12][13]. In [14][15][16][17][18], the use of wireless technologies in the field of automation of technological processes is considered, which can also be used to study heat transfer in OCF materials.…”
