Testing the impact of hydrodesulphurisation process parameters on diesel fuel properties

In this work the influence of changes in hydrodesulphurisation (HDS) process parameters (space velocity and temperature) on efficiency of sulphur compounds removal was tested. The feedstock, straight run gas oils (STGO) from Croatian crude oil used for diesel fuel production have been subject to the hydrodesulphurisation process with Co-Mo/Al2O3 commercial catalyst in a trickle bed reactor in high-pressure apparatus at the following conditions: total reactor pressure of 500 kPa, reactor inlet temperature in the range 330 - 355 °C, liquid hourly space velocity (LHSV) in the range 2.0, 2.5 and 3.0 h-1 and hydrogen/hydrocarbons ratio of 120. The laboratory high-pressure apparatus was upgraded by implementation of a modern computer-based control system. Control system supports experimentation aiming better process conditions monitoring and control with the purpose of improved repeatability and achievement of safe operation.
