Tóm tắt:Title screen
This study presents the development of a macroscopic three-dimensional two-fluid Eulerian- Eulerian model for tracking the evolution of solid and gaseous phases in a Fluid Catalytic Cracking (FCC) riser, with a zeolite catalyst and the petroleum feedstock being modelled respectively as the continuous solid and gaseous phases. The solid phase was modelled by using the kinetic theory of granular flow (KTGF) for particulate phases. By using the commercial software ANSYS Fluent, the Computational Fluid Dynamics (CFD) investigation of the gas-solid hydrodynamics within the catalytic cracking riser was carried out. The aim was to develop a computational hydrodynamic model and to illustrate the work of the new model by examining the several fluidized beds with gradually increasing complexity. Overall, the results obtained for the simplified designs show similarities to the operation of a real-life FCC unit. The achieved outcomes will be valuable for further improvements of modern FCC risers.
