Abstract��
The distributions of Saturates,Aromatics,Resins,and Asphaltenes (SARA) four components in the heavy oils are very important to heavy oil processes because they directly affected the yield and quality of products in processing technologies.To provide a basic data for further exploration of the chemical effects of ultrasound on the four components of heavy oil,the content change of four components with ultrasound was studied.The experiments explored oil temperature,ultrasonic power and ultrasonic frequency which affect the four components of heavy oil.The results showed that the distributions of SARA could be affected by ultrasound,the content of saturates,aromatics could be increased and resin content be decreased.In the experiments,when ultrasonic temperature was 50—60 �� for 15 min,ultrasonic frequency 28 kHz,ultrasonic power 200 W,compared with the raw heavy oil,the rates of saturates and aromatics were increased by 5% and 4%,and the resin and asphaltene were reduced by 2.5% and 7.5%,��respectively��.
