石油及石油-煤沥青混合物制取浸渍剂沥青的研究进展

Advances in Production of Impregnating Pitch from Petroleum Bitumen and Petroleum-coal Bitumen Mixture

综述了国内外浸渍剂沥青制备技术的研究现状与发展方向,主要介绍了以石油沥青和石油-煤沥青为原料制备浸渍剂沥青的技术。根据产品质量要求,需要对原料作相应的改性。介绍了对原料进行改性的工艺。认为石油沥青经过改性后制备浸渍剂沥青符合环保和经济性要求。

The research status and development orientation of impregnating pitch at home and abroad are described,focusing on the technologies of production impregnating agent pith taking petroleum pitch and petroleum-coal tar pitch blends as raw material.According to the quality of impregnating pitch,the feed stock needs to be modified.The processes of feed stock modifying are introduced.It is in keeping with the requirement of environmental protection and economic efficiency to produce impregnating pitch from petroleum bitumen modified.
