Summary: This work explores an eco-friendly approach to extracting cashew nut shell liquid (CNSL) and refining cardanol from cashew nuts produced in Hainan, China. CNS, which is usually considered waste from agricultural processing, can be extracted into valuable CNSL using solvent extraction or supercritical CO2 extraction. The composition of extracted CNSL varies with different conditions, and less polar solvents extract more CNSL. Supercritical CO2 extraction also shows superior performance in CNSL extraction as an environmentally friendly method. CNSL from Hainan cashew nuts contains a high amount of anacardic acid. The extracted CNSL can be decarboxylated and separated to obtain a mixture of cardanol consisting of four olefins with different numbers of double bonds. Cardanol can be converted to saturated cardanol and high purity cardanol monoene through catalytic hydrogenation and catalytic transfer hydrogenation, respectively. Both saturated cardanol and cardanol monoene have promising prospects due to their chemical structure.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
