Heavy fuel oil compositions exhibiting improved stability |
摘要 |
Heavy fuel oil compositions exhibiting improved stability in respect of the flocculation of asphaltenes. These compositions result from the mixing of a) at least one unstable heavy fuel oil with b) an intermediate deasphalting fraction, optionally modified, for example by reaction with maleic anhydride and then with a compound containing amine and/or hydroxyl functional groups. |
