| Abstract: | A test on the extraction of reformed wide-cut deheptane oil has been performed in a small C.S. sieve-tray extraction column. The effects of the conditions such as extraction temperature, solvent/feed ratio, water content on selectivity and aromatic yields were observed. It shows that the operation condition of S/F=4, water content in solvent 3%(m) and operation temperature 60℃ are very suitable for getting higher selectivity and the highest aromatic yield. |
