• In this paper, comparison is made for the axial & radial distributions and the radial non-uniformity index of solids volume fraction between the pre-lifting scheme with central tube and the scheme without central tube. Both two pre-lifting schemes can be divided into three regions. More uniform distribution and higher values of solids volume fraction are obtained at region III in the pre-lifting scheme with central tube than those in the scheme without central tube. The suggested installation height for the feedstock nozzles should be located near 1.3 m in the pre-lifting scheme with central tube. A higher location (h > 2.3 m) is suggested for installing the nozzles in the scheme without central tube. The pre-lifting scheme with central tube can improve the distribution of catalysts much more than that without central tube.
