Abstract: 

IN THE PRESENT RESEARCH, THE DIFFERENCES BETWEEN ONE-DIMENSIONAL AND TWO-DIMENSIONAL MODELING OF CATALYTIC NAPHTHA REFORMING PROCESS IN AXIAL FLOW SPHERICAL PACKED-BED REACTOR (AF-SPBR) HAVE BEEN INVESTIGATED. AFTER WRITING THE MASS, ENERGY AND MOMENTUM BALANCES, THERMODYNAMIC AND KINETIC EQUATIONS, AND AUXILIARY RELATIONS, THE REACTOR HAS BEEN MODELED WITH COMPUTATIONAL FLUID DYNAMICS (CFD) SOFTWARE. IN THIS MODELING, THE VELOCITY, TEMPERATURE, AND CONCENTRATION DISTRIBUTION ARE CONSIDERED IN BOTH AXIAL AND RADIAL DIRECTIONS. THE VELOCITY PROFILE IS PICTURED TO ILLUSTRATE THE RADIAL AND AXIAL MOVEMENT OF THE FLUID THOROUGH THE PACKED-BED OF THE SPHERICAL REACTOR. IN ADDITION, THE DIFFERENCES BETWEEN TEMPERATURE AND CONCENTRATION DISTRIBUTION OF ONE-DIMENSIONAL AND TWO-DIMENSIONAL MODELING THROUGH THE RADIUS AND THE LENGTH OF THE REACTOR ARE INVESTIGATED. THE EFFECT OF THE ENTRANCE VELOCITY ON THE OUTPUT CONCENTRATION OF NAPHTHENE AND AROMATIC IN ONE-DIMENSIONAL AND TWO-DIMENSIONAL MODELING IS ALSO PRESENTED.
