Process for selectively removing lower molecular weight naphthenic acids from acidic crudes |
摘要 |
A process for selectively removing lower molecular weight naphthenic acids from an acidic crude by treating the crude with a small pore hydrotreating catalyst at temperatures of from about 200 DEG to 370 DEG C. Removing these lower molecular weight naphthenic acids reduces the corrosive nature of acidic crudes.
