| Abstract: | In a φ500mm cold model of radial flow moving bed reactor, the distributions of pressure and velocity in the main channels were studied under four kinds of gas flow mode: inward Z gas flow; inward gas flow; outward Z gas flow and outward II gas flow. It was found that in the outward n gas flow mode, the axial non-uniformity of gas is minimum (less than 5% under the experiment condition). Correlations about the momentum recovery factor K were proposed. The distribution of pressure in the main channel can be predicted accurately. |
