THERMODYNAMIC INDEXES OF IRON-CONTAINING CATALYSTS AND THE KINETICS OF HYDROGENATION OF HIGH-VISCOSITY KARAZHAMBAS CRUDE-OIL

Pyrite has been treated in an autoclave with the use of different redu cing media (CO, CO/H-2, CO/H2O) at 673 K and an initial gas pressure o f 4.0 MPa. Equations of the temperature dependence of the specific hea t have been derived, and the thermodynamic functions S-0(T), H-0(T)-H- 0(298.15) and Theta*(T) of pyrrhotines have been calculated. The Gibb s free energy, enthalpy, entropy and equilibrium constant of pyrite re duction have been determined. An investigation has been made of the ki netics of hydrogenation of high-viscosity crude oil of the Karazhambas field (Kazakhstan) in the presence of Write. Effective values of the reaction rate coefficients and the apparent activation energies have b een determined.
