THE EFFECT OF MASS TRANSFER RESISTANCE ON THE KINETICS OF THIOPHENE HYDRODESULFURIZATION

In kinetic study of catalytic reactions, due to mass transfer rate can be effective in adding to chemical kinetic, so it is necessary to study these effects firstly. The present work investigates the hydrodesulfurization of gas condensate, to determine the effect of interface mass transfer resistance. The entire work was performed in a hydrodesulfurization (HDS) pilot plant unit, located in Research Institute of Petroleum Industry (RIPI). For the tests, a commercial HDS catalyst (CoMo) was used and the feed (gas condensate) provided by South Pars gas field of Iran. The objective of the work was to investigate effect of mass transfer limitations in catalytic reaction of thiophene HDS. It was verified that mass transfer resistance has not a significant effect on the reaction rate. The results are presented as graphs and tables.
