Abstract: By applying rotating packed bed to replace conventional packed tower as desulfurization equipment, the effect of desulfurization efficiency were investigated with the dinuclear cobalt-phthalocyanine sulfonate (PDS) as catalyst in different volume ratio of gas-liquid, rotating speed, temperature, concentration of Na2CO3 and PDS etc. The experimental results showed that the removal efficiency of desulfurization could reach 99.0% under proper conditions. Compared with tower equipment, the high gravity method had many advantages, including higher desulfurization, lower ratio of liquid-gas, smaller equipment size.
