Research Institute of Petroleum Industry

Applied plans/ industry problem solving:

Hydrodesulphurization process is wildly used in petroleum industry for sulfur removal of various fractions, i.e. naphtha, kerosene and gas oil. Gas oil hydrodesulphurization process is carried out over Co-Mo/Al2O3 catalyst. Nowadays the sulphur contents of diesel and gasoil fractions in Iran are 7000-10000 ppm which is very high in comparison with EURO4 (less than 50 ppm ) and EURO5 (less than 10 ppm) standards. Due to its high use and importance, RIPI has developed the production conceptual design package of this catalyst.


Mega Project:

The required gas oil hydrodesulphurization catalyst for our refineries is 200 metric tons per annum which is totally imported from abroad.                                        


In-home making:

Conceptual design package for production of this catalyst in the scale of 800 kgs per day has been prepared. The design package contains process description, equipment specifications, stream flow parameters and block flow diagrams.


prevention of currency leave:

Buying the catalyst for refineries and petrochemical complexes from abroad requires millions of dollars so in home production of this catalyst will save this cost for industries.                                                                                                      



The production know-how is available for commercialization


Economic justification:

The feasibility study showed that the in-home production of this catalyst is economically justifiable.


Contractor approval:

The catalyst production know-how is now ready to be transferred to developer.
