Method for reducing the naphthenic acidity of petroleum feedstocks, and use thereof |
| abstract |
The invention relates to a method for reducing the naphthenic acidity of a petroleum feedstock having a neutralization index of 0.5 to 10 mg of KOH/g and a water content lower than 0.2 wt %, wherein said method comprises contacting the petroleum feedstock with a compound selected from the oxides, hydroxides and alkoxides of an HA group alkaline earth metal, the contact being carried out at a temperature lower than or equal to 150° C. The implementation of the method according to the invention, and in particular in the absence of water, makes it possible to reduce the naphthenic acidity and to prevent the formation of naphthenate salts that may subsequently reform naphthenic acids. |
