Abstract
|
High total acid number (TAN) crude oils contain large amounts of naphthenic acids that could create serious corrosion problems in the oil refining process. Authors examined the catalysts that can make the naphthenic acids in crude oil to be decomposed to effectively decrease the TAN of the crude oil. This would decrease corrosion of the facilities. The results indicated that Mg–Al hydrotalcite/γ-Al2O3 effectively removed the naphthenic acids in high TAN crude oils, and the catalyst prepared with the ball-rolling method possessed a high mechanical strength and good pore structures. |
