The behaviour of symmetric binary Lennard-Jones mixtures in narrow slit-like pores has been studied. Gibbs ensemble Monte Carlo simulation techniques have been used to examine the influence of confinement on phase separation for pores of different size and for different kinds of wall-fluid interaction. The phase coexistence curves and density profiles have been calculated. The critical point is shifted towards higher densities when the external potential becomes stronger or the pore width becomes smaller. Thus, the effect of confinement is to reduce the region of immiscibility.
