“…Parameters of equations 1-3 were determined based on data obtained with hydrotreating of this feed at various process conditions. They were β=1.73, E f = 125.3 kJ/mol, E r = 210.0 kJ/mol, k f0 = 2.79x10 8 h -1 MPa -β and k r0 = 2.432x10 16 h -1 .…”

“…alkyl dibenzothiophenes) those contain one or two alkyl groups adjacent to the sulphur atom (e.g. 4 methyl or 4,6 dimethyl dibenzothiophene) [16][17][18]. These alkyl groups sterically hinder the connection of the sulphur atom to the active centre of the catalyst and the conversion of this type of sulphur compounds referred as hindered dibenzothiophenes, requires high temperature and pressure, and low LHSV [3,15,19].…”

Keywords gas oil · hydrodesulphurization · hydrodearomatization · NiMo · noble metal catalyst IntroductionThe quantity requirements for high quality middle distillates (diesel fuel and JET) continuously increased in the last decade, especially in the European Union. Figure 1 shows that the increase in consumption of diesel fuel was more than 30% in the time period of 1999-2007, and this tendency was interrupted by the world economy crisis [1]. At the same time, the consumption for motor gasoline considerably decreased.

“…The grinding of MoS 2 in a dispersed liquid medium results in physical adsorption of the solvent on its surface [4]. Therefore, the fi nal physicochemical properties of MA-MoS 2 can be signifi cantly affected by the dielectric permittivity (ε) of the dispersion medium [17], which, in turn, is a key infl uencing factor for the Coulomb force between point charges on the surface of the material subjected to grinding. This assumption is supported by the above discussions on the data of Table 2 and Table 3.…”

Novel Molybdenite-Based Nanopowder Catalysts for Hydrodesulfurization

et al. 2021

Novel bulk single-component sulfide catalysts were prepared under the conditions of solid-phase dispersion of МoS2 molybdenite at various mechanical treatment times and various amounts of polar and nonpolar liquid microadditives. The chemical degradation of the samples in the air was found to lead to the formation of surface sulfate anions that shield catalytically active Mo sites. Indirect correlations of the hydrodesulfurization ability of MoS2 powders with the concentration of sulfate anions on their surface, and with the aqueous pH in the powder suspensions, including the dielectric permittivity of the organic dopants, can serve as reference indicators of high catalytic activity in the model reaction of dibenzothiophene hydrogenolysis. The study identified the most active sample able to run for an extended time during multiple cycles without losing its catalytic properties. Also, the paper discusses the dibenzothiophene conversion routes, the product composition, the probable structure of active sites in the catalysts, and the desulfurization degree of diesel fuel components.
