- Abstract
Background. At JV Uz-Kor Gas Chemical LLC 102,000 tons of pyrolysis distillate, 8.000 tons of pyrolysis oil and 10.000 tons of resinous products are annually produced. These products are not processed in the republic. Purpose. Development of technology for the processing of pyrolysis distillate and its industrial testing at Kungrad Gas-Oil LLC. Its peculiarity is the high yield of gasoline due to the complex hydrodynamic processing of the pyrolysis distillate during its intensive contact with the catalyst. Methodology. The experiments were carried out on a pilot plant for studying the processes of catalytic processing of pyrolysis distillate. The quality indicators of pyrolysis distillate samples were determined according to GOST 9736-68 and GOST 2177-99, sulfur determinations according to GOST 1437-75. Originality. The values of pyrolysis distillate hydrogenation regimes are revealed. Qualitative indicators of obtained samples of distillate fractions meet the requirements of the company's standards KSt 16472899-022:2006 for light naphtha and KSt 16472899 -026:2006 for heavy naphtha. Findings. The mass fraction of sulfur in the pyrolysis distillate fractions, in the presence of the AKM catalyst at 350°C and 3.5 MPa, decreases by 70–80 mg/kg, and the mass content of resins in their composition decreases by 104–120 mg/100 cm³. At the same time, the density of the obtained distillate fractions decreases by 7.3÷8.9 kg/m³, and the temperature regime of their distillation does not change significantly.
