Abstract  

Isobaric heat capacities of natural mixtures were determined up to 40 MPa with a modified C-80 Setaram calorimeter equipped with cells designed for high pressures. The systems investigated were heavy distillation cuts with respective boiling points of 150, 200, 250 and 300°C. These experimental data were used as discriminatory values to test thermodynamic models and more precisely to choose among the great number of equations of state and mixing rules proposed in the literature, the most appropriate for the characterization of the heavy components.

Abstract  

With the use of various calculation methods, unknown thermodynamic properties (TP) of Bi2O5 and BiO2, as well as the temperature dependencies of reduced Gibbs energy (TDRGE) were determined. With the help of thermodynamic simulation (TS) methods at 300–1500 K, common P=105 Pa the thermal decompositions of condensed Bi2O5, BiO2, Bi2O3 and BiO have been investigated in initial atmosphere of O2 and Ar. Every condensed substance was presented as the individual phase. It was found that BixOyoxides have temperature stability fields and also districts of possible mixture formation. During equilibrium heating of BixOy oxides the various types of phase transformations were observed. The characteristics of some transformations were estimated.
