Development on the Purification Techniques of Asphalt Fume From the Production of Prebaked Anode for the Aluminum Industry

With the development of aluminum industry, carbon industry also develops quickly. Consequently the pollution of asphalt fume emitting from the production of prebaked anode becomes more and more serious; it's time to investigate and develop new techniques to control that. In this paper, study status of this technology at home and broad is introduced, including control technology and the existed problems. In order to solving the key problems in asphalt fume treatment, viscidity mechanism of asphalt fume can be studied from the viewpoint of quantum theory,analyzing the relationship among the viscidity,composition and phase distribution,developing high efficient additives for the improvement of viscidity of asphalt fume, reaching the aim of purification and promoting the sustainable development of aluminum electrolysis and the relevant industries.
