Аннотация: Heavy residual stock obtained by the vacuum distillation of the hydroconversion products (T = 425°C; P = 6 MPa; a nanoheterogeneous catalyst based on molybdenum sulfide) of heavy residual carbonic (high-sulfur) oil is a starting material for gasification. The equilibrium composition of gasification products (P = 0.1 MPa; α = 0.3; 20 wt % H2O) over the temperature range of 519–1626 K was calculated using chemical thermodynamics methods. The yields of the main compounds of Mo, V, Ni, Ag, Au, As, Co, Ga, Fe, Al, Si, Ca, and Mg (mol/kg residue) and their amounts in gas and condensed phases were determined. The volumes and compositions of gaseous products were also determined as functions of temperature at different sulfur concentrations of 9.5 and 4.75 wt % in the starting vacuum residue.
