CA 2718317

Total acid number and/or corrosiveness of a crude or refined hydrocarbon, where the total acid number and/or corrosiveness is due to the presence of acid compounds such as carboxylic acid' (naphthenic acid), may be reduced by treating the hydrocarbon with a metallic overbase.

Selon linvention, l'indice d'acide total et/ou la corrosivité d'un hydrocarbure brut ou raffiné, l'indice d'acide total et/ou la corrosivité étant dus à la présence de composés acides tels que l'acide carboxylique (acide naphténique), peuvent être réduits grâce au traitement de l'hydrocarbure par une surbase métallique. L'effet de ce traitement peut être sensiblement amélioré par la présence d'un agent de transfert d'hydrogène. Il est entendu que l'abrégé ne sera pas utilisé pour interpréter ou limiter la portée ou la signification des revendications.
