Abstract
The hydrofining of semicoking coal tar from the Shubarkul deposit (Republic of Kazakhstan) in the presence of nanoheterogeneous molybdenum sulfide catalyst systems (Mo content, 0.025–0.12%) was studied in order to intensify processing technology. The catalysts were in situ prepared in the coal tar with the addition of a sulfidizing agent—elemental sulfur in an amount of 0.03 –0.09 wt % on a raw material basis. It was found that the effective Mo content of the catalyst was 0.025%, and the amount of sulfur was 0.03%, which made it possible to obtain a maximum yield of total liquid products (76.8%), which mainly contained diesel fuel fractions, at 5 MPa and 400°C.
