摘要：研究了长江口表层沉积物微粒促进柴油、重油分散的机理,发现颗粒物粒径分布、悬浮颗粒物浓度、油类型是影响油分散效率的主要因素.粒径越小的微粒所占比重越大,颗粒物浓度越高,则油分散效率越高.悬浮颗粒物可短时间内与油滴发生聚结,对重油的分散效率高于对柴油的分散效率.盐度的升高在一定范围内可促进油的分散.
The influence of clay minerals from superficial deposit of Yangtze estuary on diesel and heavy oil dispersion were studied. The results found that the size distribution of particulate matter, the content of particle and the type of oil were important parameters. High ratio of microsized particle and particle content was proved to be good for oil dispersion. The suspended particles could be aggregated with oil droplet in short time. More heavy oil was dispersed by particles than diesel. Increase of salinity in a specific range can improve oil dispersion. 
