【摘要】 采用Winner99显微颗粒图像分析仪分析了水溶性盐在渣油中的分散性,建立了用分散性能参数来评价水溶性盐在渣油中分散效果的方法。在原有模型的基础上,建立了适合渣油体系的分散动力学模型,考察了水溶性盐在不同的渣油中分散性随时间变化的动力学过程。结果表明,该分散动力学模型很好地解释水溶性盐在不同渣油中分散性的变化趋势。在表面活性剂CTAB和Tween80存在下,水溶性Mo盐在克拉玛依常压渣油(KLAR)中的分散参数随时间的变化关系符合Lorentz数学模型,水溶性Ni盐在辽河常压渣油(LHAR)中的分散参数随时间的变化关系符合Gauss数学模型;在表面活性剂CTAB存在下,水溶性Co盐在大庆常压渣油(DQAR)中的分散参数随时间的变化关系符合Boltzmann数学模型。更多还原

【Abstract】 The dispersion of water-soluble salt was analysed by microscopic image analyzer,the dispersion effect of water-solubility salt in residue was evaluated by dispersion parameter.Dispersion dynamic model was built on the base of pro-model,the dispersion process of water-soluble salt was studied with the change of time in residue.The results indicated that the model explained well the changing trend of water-soluble salt in different residue,the dispersion parameter of water-soluble Mo salt changing with time accord with Lorentz mathematical model in KLAR,water-soluble Co salt accord with Boltzmann mathematical model in DQAR and water-soluble Ni salt accord with Gauss mathematical model in LHAR.更多还原
