摘要：
The effect of ionic liquid concentration on the content of four components and structural composition of heavy oil was studied by using ultrasonic-assisted nickel based ionic liquid. The results reveals that compared with crude oil and individual ultrasonic crude oil, the combination of ultrasonic wave and ionic liquid can achieve synergistic effect. Saturate increased and aromatic decreased gradually as the increase of the concentration of ionic liquid. The structure of resin and asphaltene has been characterized by infrared and nuclear magnetic resonance spectroscopy. It has been indicated that the structure of polyaromatic compounds can be obviously changed and mainly occurrence in alkyl side chain cleavage and cycloalkanes ring-opening reaction.
