Gas-solid two-phase flow of the quick-contact cyclone reactor used in FCC was simulated with the multi fluid Eulerian model, especially the velocity field and volume fraction of solid in the mixing chamber was researched. The results show that flow pattern and catalyst particles concentration are non-uniform in the direction of axial, radial and tangential. The tangential gas admission increases turbulent intensity, it has a great benefit on spreading the catalyst particles uniformly, enhancing gas-solid contact effect. This work could offer a base for the structure optimization of the quick-contact reactor.
