Abstract

The favourable effect of shaping the polylobed extrudate or pelleted Rashig ring catalyst particle leading to the higher values of internal diffusion effectiveness factor computed from the numerical solution of the pertinent partial differential equations was confirmed by the experimental data, measured during the gas oil hydrodesulphurization in the Berty's type autoclave at 300°C and 3 MPa using both own cobalt-molybdenum on alumina catalysts and industrial ones. The influence of calalyst particle diameter on HDS activity is also discussed.

Analysis of coke deposition profiles in commercial spent hydroprocessing catalysts using Raman spectroscopy
2007, Fuel
The distribution of coke inside the pellets of several industrial spent hydroprocessing catalysts was analyzed using Raman spectroscopy. The shape of the coke profiles gives us information on the deactivation mechanism and the magnitude of diffusion limitations. Samples taken at the end of run showed the most pronounced coke profiles. Typical M-shaped profiles observed in a guard bed catalyst suggest a sequential deactivation mechanism and a strong diffusion resistance. Consequently, it is concluded that near the end of life the catalyst effectiveness factor can be significantly reduced by coke deposition.
Reaction order and role of hydrogen sulfide in deep hydrodesulfurization of gas oils: Consequences for industrial reactor configuration
1999, Fuel processing technology
Deep desulfurization of gas oils to sulfur levels below the currently legislated 0.05 wt.% is rendered difficult by the presence of refractory species as part of a spectrum of sulfur compounds that have widely differing reactivities. This distribution of reactivities is reflected in a high apparent order (approximately 2) in total sulfur for a plug–flow reactor. The consequences of this apparent kinetic behaviour for required catalyst volumes and axial profiles of hydrogen sulfide in a reactor for deep desulfurization are examined. Hydrogen sulfide proved to strongly suppress the conversion rate of sulfur compounds, including that of the refractory alkyl substituted dibenzothiophenes crucial for deep desulfurization. A number of process configurations are discussed that avoids or reduces the problem of hydrogen sulfide inhibition. These include several variants of a two-step process in which the bulk of sulfur is removed in a first step, followed by further desulfurization down to low sulfur levels in a second step with fresh, H₂S-free hydrogen gas. The theoretically most ideal option, that of operation with countercurrent flow of oil and gas, is not possible in packed beds of the usual catalyst particles because of the occurrence of flooding at industrially relevant fluid velocities. Some novel reactor concepts based on special structured packings or monoliths that allow such countercurrent operation are presented.
