This work discusses the phase behavior of conventional liquids and their binary mixtures in the presence of graphene genealogic tree nanoparticles. An algorithm for evaluation of critical parameters shift after adding the nanoparticles to the pure liquid is applied to estimate critical point of nanofluid. It is argued that dimensionless thermodynamic surfaces of reference liquid and nanofluid with volume nanoparticle concentration less than 5% are coincided. A global phase diagram approach is proposed to evaluate a possible azeotropic states in binary mixtures after nanoparticles doping. The influence of graphene genealogic tree nanoparticles (carbon nanotubes-CNT, fullerenes-C-60 , and graphene flakes) on the liquid-liquid equilibria is discussed. The change in location of upper critical end point (UCEP) for liquid-liquid coexistence curve of the mixture of nitrobenzene and heptane and system of nitrobenzene, heptane and graphene genealogic tree nanoparticles is predicted.
