This thesis is devoted to several studies which aim at investigating the link between the Boltzmann equation for gaseous mixtures and the Maxwell-Stefan equations, modelling purely diffusive phenomena inside a gas. Our analysis is built on a linearization of the solution of the kinetic equation around a local Maxwellian state characterized by different bulk velocities for each species of the mixture, but having the same order of mag- nitude of the scaling parameter which prescribes the diffusion asymptotics. In a first part, we start by showing that the Boltzmann operator linearized around such a Maxwellian, which does not constitute an equilibrium for the gas, exhibits a quasi-stability property on its spectral gap : the spectral gap known...
