【摘要】 石油溶液是以沥青质为胶束中心,胶质为溶剂化层,瓦斯油分为分散介质的胶体分散体系。形成沥青胶束的作用力为偶极相互作用、电荷转移作用和氢键作用,它们的实质是酸碱相互作用。石油胶体溶液具有胶体分散体系的一般特征。应用DLVO理论和空间稳定理论能够解释石油胶体溶液的物理结构和一些行为特征。更多还原

【Abstract】 The petroleum solution is a colloidal dispersion in which the asphaltene comprises the micellar nucleus, the resin forms the solvation layer and the remaining gas oil acts as the dispersing medium. The fundamental interactions by which the asphaltene micelle forms include the dipole-dipole interaction, the electric charge transfer and the hydrogen bonding, the essence of which is based on acid-base interactions. The petroleum colloidal dispersion exibits the general characteristics of the common colloidal dispersions. Theories of the static charge stabilization and the steric stabilization are proved useful to some extent to explain the physical configurations of the petroleum colliodal dispersion and some of its thermodynamic and kinetic behaviors.更多还原
