    Abstract

    An uncertain aspect of Fluid Catalytic Cracking Unit is the description of Fluid Solid Mixing in the riser entrance. Most of the existing model assume an instant mixing of solid and gaseous reactant. Howeever a finite mixing length at the bottom of the riser may have a pronounced effect on FCC operation, particularly when only very short residence time are allowed in the commercial FCC riser. In this study transient gas and solids hydrodynamic were predicted in 3D riser section of FCC unit. The mixing of gas-oil feed and catalyst particles has been investigated by an Eulerian Eulerian aprroach using Fluent 6.2 CFD code. The CFD model provided important information about the gas-solid flow pattern, and also predicted the flow yield of velocity and volume fraction on computational grid of the solution domain.
