AI Technical Summary
Existing technologies for cleaning oil sands suffer from high energy consumption, low oil removal efficiency, difficult post-processing, and potential environmental hazards, especially in oil spills near coastlines. Traditional cleaning agents require auxiliary heating and are ineffective in both freshwater and seawater environments.
A high-charge cellulose nanocrystal compounded with a nonionic surfactant is used to form an oil sand cleaning agent. When used at room temperature, the high-charge cellulose nanocrystal repulsion between itself and the negatively charged sand particles improves the oil removal efficiency and maintains stability in oily emulsions, simplifying the post-treatment process.
It achieves efficient cleaning of oily mud and sand at room temperature, reduces the amount of cleaning agent used, shortens the post-treatment time, and is suitable for both freshwater and seawater environments. It has a good oil removal effect, especially in oil spill accidents near the coastline, and has a strong resource recycling capacity.
