摘要: The hydrodynamic characteristics of the riser a FCC plant are investigated in cold pilot plant. results checked and completed with measurements made real operating units. In both cases, tracing gas, sampling probes, γ-tomography were used. gas solid velocity profiles described by using plug-flow model radial dispersion. profile is formally represented an Ostwald−de Waele type equation. axial concentration fitted to data obtained commercial unit. dispersion coefficient directly measured kinetics reactions occurring during catalytic cracking microreactor 19-lump including deactivation coking catalyst. A combination this reaction able predict good precision yields different product families industrial It checked...
