| 摘 要： | 为了进一步认识蜡的结晶过程,采用质谱、高温气相色谱和核磁共振碳谱对蜡进行了表征,利用偏光显微摄像技术拍摄了南阳减三线蜡和荆门轻脱加氢处理蜡在不同黏度脱蜡油中的蜡晶照片,进行了南阳系列石蜡在南阳减三线脱蜡油中的结晶实验.结果表明,蜡在不同黏度脱蜡油中结晶时,晶形会发生改变,这可能是由于蜡分子在结晶扩散时存在"纵向扩散"和"横向扩散"的缘故;烃类组成相似的蜡在同一脱蜡油中结晶时,随着相对分子质量的增加,蜡晶粒度增大,这可能与蜡分子间作用力及蜡的析出温度有关.

| Abstract: | In order to further understand the wax crystallization process,the waxes were analyzed by MS,HTGC and 13C NMR,and the crystal photomicrographs of the waxes from the furfural raffinate of Nanyang vacuum 3rd side cut and Jingmen hydrotreating-deasphalted oil(DAO) were taken in the dewaxed oils with different viscosities.The experiments were carried out,in which Nanyang paraffin wax crystallized in the dewaxed oil of Nanyang vacuum 3rd side cut.The results showed that the crystal form of the wax changed when i... |
