中文摘要: 以石化行业重油精炼加氢脱硫过程中产生的废加氢催化剂为原料,采用还原熔炼工艺回收其中的有价金属。结果表明,在SiO2添加量40%、B2O3添加量10%、CaO添加量29%、Na2CO3添加量80%、冰铜添加量100%、褐煤添加量5%、CaF2添加量5%、1 450 ℃还原3 h,渣计Mo、Co、Ni和V的回收率分别为98.54%、96.51%、99.47%和37.41%。
Abstract:Valuable metals were recovered by reduction smelting process from spent hydrodesulphurization catalysts produced in refining hydrodesulphurization process of heavy oil in petrochemical industry. The results show that recovery of Mo, Co, Ni and V calculated by slag is 98.54%, 96.51%, 99.47% and 37.41%, respectively under the conditions including addition of SiO2, B2O3, CaO, Na2CO3, copper matte, lignite, and CaF2 of 40%, 10%, 29%, 80%, 100%, 5%, and 5%, respectively, temperature of 1 450 ℃, and smelting time of 3 h.
