高原电解铝生产中高水分水合沥青焦油的成因分析

Causes of Formation of High Hydrate Coal Tar Pitch by Asphalt Gas Decontaminating during Aluminum Electrolysis in Plateau

高原电解铝碳阳极生产中存在沥青烟气净化产生高水分水合焦油而无法直接利用的的技术难题。在研究生产实际的基础上,得出高原电解铝碳阳极生产中沥青烟气净化产生高水分水合沥青焦油的成因,主要为比电阻、气压、生产环节的影响,为进一步研究水合沥青焦油分离技术提供基础。

Due to the formation of high hydrate coal tar pitch which cannot be used directly, there are technical problems during aluminum electrolysis anode carbon production in plateau. On basis of the practical production, the causes of forming high hydrate coal tar pitch by asphalt gas decontaminating are put forward. The key influencing factors are resistivity, atmospheric pressure, and manufacturing process. These works lay an experimental base for the future research of separation technique of hydrate coal tar pitch.
