摘要 |
<p>Process for recovering and moving highly viscous petroleum products, by the use of aqueous dispersions in the presence of sulphonate dispersers prepared: a) by increasing the molecular weight of steam cracking fuel oil by its oligomerization in the presence of a catalyst selected from BF3 and complexes thereof with strong acids; b) sulphonating the compound obtained from step (a) by reaction with a sulphonating agent, preferably SO3; c) neutralizing the sulphonate obtained from step (b) by treatment with hydroxides selected from the hydroxides of alkaline or earth alkaline metals or ammonium.</p> |
