چکیده مقاله:
This work aims to test the application of computational fluid dynamics (CFD) modeling to fixed bed catalytic cracking of n-Heptane. in this study catalytic cracking of n-Heptane was simulated in 3D and with 25 molecular reactions that had presented before. The first reaction coefficients were corrected in 3D geometry of reactor using CFD. There is a good agreement between experimental data and CFD results. Velocity vectors, vorticity, stagnation points and effect of these parameters on coke deposition were investigated. The coke precursor’s concentration profiles were investigated in different space times and there was a maximum point in the concentration profiles due to secondary reactions.
