Abstract

In order to increase the depth of oil refining, as one of the ways to effectively use heavy oil residues in relatively low temperature conditions, the processes of producing pitches for various purposes from them are being studied. The conducted studies examined the possibility of producing pitch using heavy distillates of catalytic cracking and heavy pyrolysis residue as raw materials. The change in the physical properties of the product depending on temperature was determined. Experiments were carried out on the GAZAKKROM-5 installation to determine changes in the softening temperature and the yield of the α-fraction depending on the raw material. The physical properties and changes in the chemical composition of the obtained oil samples were studied. When comparing the results obtained, it was found that the yield of the α-fraction from pitch obtained from both the heavy cracking distillate and the heavy pyrolysis residue is approximately the same. In addition, it was found that the softening temperature of pitch obtained from heavy pyrolysis residue is 90℃, and for pitch obtained from heavy distillate of catalytic cracking, this figure is 84-85℃. Thus, since the supply of heavy pyrolysis residue is small, the prospects for using heavy catalytic cracking distillate as a raw material in the production of cake are justified.
