| Abstract |
In this study, we investigated the dispersion behavior of asphaltenes in heavy oil containing oligomeric styrene copolymers as dispersant. When we compared the effects of the types of functional groups on the asphaltene dispersion, we found that the sulfonic acid groups were better than the carboxylic acid groups. In addition, we also observed that the maleic acid was the best. This suggested that the amounts of carboxylic acid groups were important for the asphaltene dispersion. Furthermore, we found that, with decreasing molecular weight of the oligomeric copolymers, the dispersion behavior of the asphaltenes was improved. This result indicated that there was a critical molecular weight of the copolymer for the better dispersion of asphaltenes, above which the copolymer started to act as linkers between asphaltenes and, thus, lead to the sedimentation of the asphaltenes. |
