Speed up the absorption of viscous crude oil spill by Joule-heated sorbent design

Although ocean crude-oil spill accidents did not frequently happened in the past,it really caused great damage to the marine ecosystem once it happened.Because of the spreading and weathering,crude-oil spill usually covers a large area of water surface and its viscosity is very high,which brings human great trouble to clean it up.Dispersant and in-situ burning were frequently used in the past crude-oil spill accidents,
