Acid removal from crude oils by catalytic esterification naphthenic acid catalize by Mg/Al hydrotalcite

摘要

The presence of relatively high levels of naphthenic acids in crude oil may cause serious corrosion problem at temperature between 200 degrees C and 400 degrees C. One of the viable processes for decreasing acidity is the esterification of the present acids using an alcohol such as methanol. Therefore, the aim of this work is to develop a solid catalyst for the esterification reaction of 3-cyclopentylpropionic acid representative of the naphthenic acids.
