将机械粉碎的石油燃烧残渣与高于接化学计算量的碳酸碱、硫酸碱、氯化碱或其混合物在高于930～970℃的氧化气氛中加热,用水或水和碳酸钠溶液浸渍所得的物料后获得钒酸钠溶液,从钒酸盐溶液中除去硅酸盐等杂质,再从净化的溶液中沉淀钒酸铝、粒状聚钒酸铝和偏钒酸铝。 Heating the mechanically comminuted petroleum combustion residue with a carbon dioxide, sulfuric acid base, alkali chloride or mixtures thereof in excess of the stoichiometric amounts in an oxidizing atmosphere at a temperature above 930 to 970 ° C, impregnating the resulting solution with water or water and a sodium carbonate solution After the material is obtained, a sodium vanadate solution is obtained, impurities such as silicate are removed from the vanadate solution, and aluminum vanadate, granular poly vanadate and metavanadate are precipitated from the purified solution.
