Summary: This paper fits the adsorption isotherms of carbon dioxide on highly porous activated carbon using advanced statistical physics models to interpret the process. Physicochemical parameters were deduced through the best fitting model, showing CO2 molecules forming a single layer on modified activated carbon and mainly binding in a parallel position with adsorption energies reflecting physisorption. The use of the enthalpy function for thermodynamic evaluation in a CO2 adsorption cooling system revealed a coefficient of performance ranging from 0.09 to 0.19 at regeneration temperatures between 303 K and 343 K.

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.
