Ionic Liquids: Novel Solvents for Petroleum Asphaltenes
《Chinese Journal of Chemical Engineering》2005年第4期564-567,共4页刘艳升 胡玉峰 王海波 徐春明 纪德军 孙研 郭天民 
Supported by the National Natural Science Foundation of China (No. 20276037) and CNPC Innovation Foundation(No.03E7016)
The dissolution of petroleum asphaltenes with ionic liquids is studied for the first time. The results show that the ionic liquids could be used as novel solvents for asphaltenes. The important parameters governing th...
