Dr Narjes Abul has 17 years experience in petroleum refining hydroprocessing operations in pilot plant scale from Kuwait Institute for Scientific Research. Dr Narjes has worked in characterization of petroleum fractions using gas chromatography, catalysts evaluation and characterization also on Gas chromatographic techniques and other analytical techniques such as TGA, Elemental analysis. Specialized in coke and wax deposition especially in regeneration of used catalysts. She also worked on projects related to asphaltene nitrogen and sulfur separation from heavy oils


Investigation on the life cycle of hydrotreating catalysts in pilot plant unit are focused on the end of run and fouling problems. The one of the non conventional way of regenerating the spent catalyst is using in-situ non-oxidative regeneration of spent hydroprocessing catalyst from Kuwaiti refinery was studied. The non-oxidative regeneration treatments, including 1) washing the spent catalyst with a straight run gas oil (SRGO) at 150 and 200 oC respectively, 2) accelerated solvent extraction technique and 3) regeneration at temperature 450o C under 50 bar using H2 diluted with 0.4% of H2S. The spent catalyst and regenerated catalysts were characterized by elemental analysis, solid-state 13C Nuclear Magnetic Resonance (NMR) analysis and Fourier transform infra-red (FTIR) techniques. The regenerated catalysts were evaluated with a feedstock containing 30 vol % of coker gas oil and 70 vol % of straight run gas oil in a microreactor system. Three type of catalysts are loaded for comparison of their activity test: fresh catalyst and oxidative and non-oxidative regenerated catalysts. The results indicate that in-situ non-oxidative regeneration is able to regenerate the spent hydroprocessing catalysts under similar operation conditions of the refinery. This treatment overcomes the disadvantages of the oxidative regeneration method.”
