Abstract

Abstract
The impact of composition of blends of potential feedstock for hydrodesulphurisation on main characteristics of diesel fraction - cetane number, sulphur content, quantity of polycyclic aromatic hydrocarbons (PAH) and flash point was tested. Blends for hydrodesulphurisation were prepared from real refinery streams and the diesel fraction was prepared by fractioning the hydrodesulphurisation products into petrol and diesel fraction.
Prepared blends can be used as input feedstock at the reconstructed process units for hydrodesulphurisation of gas oils and coking petrol at Sections 200 and 500 at Sisak OR.
Sulphur removal efficiency dependency on process parameters, temperature, space velocity and hydrogen/feedstock ratio was determined for two gas oil and sulfex extract blends.
Basic physical and chemical characteristics were determined for the obtained hydrodesulphurisation products and separate diesel fraction.
