In a new built loop reactor of 14. 45m in length and 90mm in diameter,the axial diffusivi-ties of liquid and solid phase were obtained respectively. It was found that axial diffusivities ofboth the liquid and solids phases increase with the increase of liquid circulating rate, but de-crease with the increase of solids holdup. The nearly same mixing characteristics between liq-uid and solids phase implies that one dimensional pseudo-homogeneous model is practically ac-ceptable.
