Verfahren zur Gewinnung und Transport eines viskeuzen Petroleumproduktes

摘要

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.
