| Abstract: | Vanadium and molybdenum can be seperated and recovered from spent HDS catalyst by adding sodium carbonate to waste catalyst to roast it and then leach the roasted product with water.When the average diameter of particle is less than 0.06080mm,the effect of diffusion inside the particle on roasting gas solid phase chemical reaction is negligible.The recovery of vanadium and molybdenum can separately arrive to more than 90% in the roast leaching process step under the conditions of the molar ratio(Na 2CO 3/(V Mo))2.0,roasting temperature 1123K and roasting time 240min. |
