A process for reducing the total acid number (TAN) of a liquid hydrocarbonaceous feedstock, wherein the feedstock is contacted, in the presence of a hydrogen-containing gas and at a temperature in the range of from 200 to 400 °C and at elevated pressure, with a catalyst comprising an oxide of a metal of Column 3 or 4 of the Periodic Table of Elements or of a lanthanide, which catalyst is essentially free of Column 5 to 10 metals or compounds thereof, to obtain a liquid hydrocarbonaceous product with a reduced total acid number.
L'invention concerne un procédé de réduction de l'indice acide total (TAN) d'une matière première hydrocarbonée liquide, selon lequel la matière première est mise en contact, en présence d'un gaz contenant de l'hydrogène, à une température comprise entre 200 et 400 °C et à pression élevée, avec un catalyseur comprenant un oxyde d'un métal de la colonne 3 ou 4 du tableau périodique des éléments ou d'un lanthanide, ledit catalyseur étant sensiblement exempt de métaux des colonnes 5 à 10 ou de composés de ces métaux, afin d'obtenir un produit hydrocarboné liquide avec un indice acide total réduit.
