A new kinetic model has been presented, based on combination of linear driving force and fractal like approaches, for correct modeling of oil spill absorption by porous material. The derived kinetic equation is able to describe maximum capacity of porous material and diffusion coefficient of oil into pores. In this new model, the presence of various pores with different sizes is considered, accounting for real systems. The basis of this new model is the presence of different pores with different diffusion coefficients and also changes of pores filling with time based on their sizes. The presented equation has been used for kinetic modeling of oil spill absorption by different porous materials, very well.
