Аннотация

The aim of the work was to study the process of hydrodearomatization of gasoline fractions and
diesel fuels for the production of environmentally friendly fuels with a low content of aromatic hydrocarbons.
Hydrogenation of two gasoline fractions of LLP Atyrau Refinery (AR) and LLP Pavlodar Refinery (PR) and two
diesel fuels of PA and LLP PetroKazakhstanOilProducts, Shymkent (PKOP) on Rh-Pt/Al2O3 catalyst was studied.
The influence of the technological parameters of hydrodearomatization process (pressure 1-5 MPa, temperature 25-
200°C) on the content of benzene and aromatic hydrocarbons was studied. At temperatures of 50-200°C and
hydrogen pressures of 2-5 MPa, benzene is completely removed from the fractions, and the amount of aromatic
hydrocarbons is reduced by 1.5-2 times. Some operational properties (kinematic viscosity at 20°C, pour point and
cloud point, flash point, density at 20°C, iodine number, aromatic hydrocarbon content) of the initial diesel fuels of
PA and PKOP and after catalytic treatment were determined. In process of hydrodearomatization all operational
indicators were improved and approached the standards for diesel fuel, and the cetane index increased by 1-2 units.
