We consider a fluid description of a gas mixture and would like to model its diffusion. We proposeto derive this by starting out from a multi-component kinetic model. By expanding the distributionfunctions of this kinetic mixture model as a truncated Hilbert expansion we work towards the goalof deriving the zeroth-order and first-order fluid equations. The latter will give expressions for thediffusion terms. Also numerical experiments towards this goal are presented.
