The present invention is directed to a process for reducing the viscosity of hydrocarbon feeds having TAN in excess of 2 mg KOH/gm which comprises thermally treating the feed in a treatment zone at a temperature of at least about 400°F for a period of time sufficient to substantially reduce the viscosity level of the hydrogen carbon feed while simultaneously removing gaseous reaction products from the treatment zone during the thermal treating step thereby reducing the viscosity of the hydrocarbon feed.

La viscosité d'hydrocarbures, en particulier du pétrole brut, est diminuée par un traitement thermique.
