Abstract:
Desulfurization of petroleum coke by oxidation of its sulfur-containing constituents in an aqueous phase with oxygen at elevated pressures and temperatures in the batch mode (in an autoclave) was studied. Desulfurization was performed in one step in the aqueous phase under excess pressure corresponding to or exceeding the saturated water vapor pressure at 110–250°С. Atmospheric oxygen or gaseous oxygen was used as a desulfurizing agent. The dependences of the degree of desulfurization on the process parameters were determined. The highest degree of desulfurization at an oxygen pressure of 5.0 MPa and 180°С was from 32.34 (at the petroleum coke particle size of 2 mm) to 39.68% (at the petroleum coke particle size smaller than 0.5 mm). The maximal degree of desulfurization, reached at an oxygen pressure of 5.0 MPa, 220°С, and petroleum coke particle size smaller than 0.5 mm, was 51.61%.
