This paper discusses the process of hydrotreating pyrolysis distillate. The study looked at the chemical makeup and physical properties of the pyrolysis distillate, along with the features of the AKM and ANM catalysts. The optimal process parameters for hydrotreating were identified and discussed. As a result of the study, the following optimal conditions for pyrolysis distillate hydrotreating were determined: temperature – 400–420°C, hydrogen pressure – 4 MPa, consumption of hydrogen-containing gas – 200 nm³/m³ of feedstock, with a hydrogen volume fraction of 80%. Elemental analysis of the obtained hydrotreated product was conducted. The shape and makeup of the AKM and ANM catalysts were examined using scanning electron microscopy (SEM). According to the results, the AKM catalyst contains 23.07% Al, 2.2% Co, and 6.25% Mo, while the ANM catalyst contains 31.5% Al, 6.97% Mo, and 3.81% Ni. The effectiveness of the AKM and ANM catalysts was compared, and the AKM catalyst was found to work better: the nitrogen level dropped from 7.4 wt.% to 3.71 wt.%, and the sulfur level fell from 9.24 wt.% to 1.8 wt.%. As a result of hydrotreated product distillation, 58% of the light fraction boiling in the range of 35–130°C was obtained.
