Theoretical study of the catalytic desulfurization mechanism of thiiren and its methyl derivative
J.B. Mensah, Y.G. S. Atohoun, L.O. Olatunji
Abstract
The desulfurization process of compounds implicates two steps. The first step is the adsorption process on the catalytic site and the second, the
breaking of the carbon-heteroatom bond leading to the heteroatom elimination. The adsorption process of thiiren have been studied and published in
previous works. The results obtained on MoS3H3+ and MoS4H4 have shown that the adsorption of this molecule was very good on the two and three anionic
vacancies sites based on molybdenum. In the present study, we have carried out the adsorption according to vertical and horizontal geometries of
dihydrothiiren, methylthiiren, and methyldihydrothiiren, and the desulfurization of all these molecules including thiiren molecule. The results obtained
have shown that, the desulfurization of thiiren and its methyl derivate pass through the hydrogenation of the aromatic ring on the two types of catalytic
sites.

Title: The Effect of γ-Al2O3, TiO2 and ZrO2 Supports on Hydrodesulfurization Activity of Transition-Metal Sulfides

Abstract
The transition metals V, Cr, Mn, Fe, Co, Ni, Mo, Ru, Rh, Pd, W, Re, Os, Ir and Pt were deposited from aqueous solutions of their salts onto conventional
γ-Al2O3 and unconventional TiO2 and ZrO2 supports by vacuum impregnation and characterized in their sulfided
form by a model reaction of benzothiophene hydrodesulfurization. It was found that the TiO2 and ZrO2 supports influenced
predominantly positively the resulting activity of relatively low-active metals (V, Cr, Mn, Fe, Co, Ni, Mo, Ru, W and Os), whereas the highly active
metals (Rh, Pd, Ir, Pt and Re) were influenced slightly negatively or not at all by those supports compared with the γ-Al2O3-
supported system. A significant effect of the supports on the hydrodesulfurization-activity ranking of the transition-metal sulfides studied was
ascertained.

Abstract
We present density functional theory (DFT) calculations of the hydrogenation (HYD) and direct desulfurization (DDS) pathways of thiophene
hydrodesulfurization (HDS) over cobalt-promoted MoS2. We find that the Co–Mo–S edge in its equilibrium state under HDS conditions is reactive toward both
hydrogenation and C–S bond scission without the initial creation of vacancies. This can be accomplished such that additional S is bound to the Co–Mo–S
subsequent to C–S bond scission and then removed in the final reaction step. We find thus that coordinatively unsaturated sites (CUS) are present in the
equilibrium structure, and at these sites HDS can take place without sulfur removal in the first step. No traditional vacancies are formed and the
present mechanism is therefore very different from the previously proposed vacancy mechanisms requiring the initial creation of a sulfur vacancy for the
reaction to proceed. We find that Co-promotion decreases the barrier of hydrogenation reactions and active site regeneration but increases the barrier of
C–S-scission reactions. The net result of Co promotion is found to be an increase in the hydrogenation activity and also of the relative importance of
the DDS pathway. We compare our results to available experimental information and find a number of consistencies and parallels. Therefore, we can
rationalize the promoting effect of Co such that at the Co–Mo–S edge, good hydrogenation properties are combined with the ability to bind additional
sulfur upon C–S-scission. Finally, we propose that the interactions between the Co-promoted S-edge and the non-promoted Mo-edge may play a role in the
hydrogenation pathway.

Rhodococcus erythropolis N1-36, a desulfurization strain, was grown in continuous culture at 10 different dilution rates with 50 (mu)M dibenzothiophene
sulfone (DBTO(inf2)) as the growth-limiting nutrient. The steady-state biomass, concentrations of substrate (DBTO(inf2)) and product
(monohydroxybiphenyl), saturation constant (0.39 (mu)M DBTO(inf2)), and cell yield coefficient (9 mg of biomass(middot)(mu)M(sup-1) DBTO(inf2)) were
measured. Continuous cultures at five temperatures allowed calculation of activation energy (0.84 kcal(middot)mol(sup-1) [ca. 3.5 kJ(middot)mol(sup-1)])
near the optimal temperature (30(deg)C) for growth. A washout technique was used to calculate the maximum specific growth rate (0.235 h(sup-1)), a value
equivalent to a minimum generation time of 2.95 h.

Title: Extremophilic microbes: Diversity and perspectives

Abstract: A variety of microbes inhabit extreme environments. Extreme is a relative term, which is viewed compared to what is normal for human beings.
Extreme envi-ronments include high temperature, pH, pressure, salt concentration, and low temperature, pH, nutrient concentration and water availability,
and also condi-tions having high levels of radiation, harmful heavy metals and toxic compound(organic solvents). Cul-ture dependent and culture-
independent (molecular) methods have been employed for understanding the diversity of microbes in these environments. Extensive global research efforts
have revealed the novel diver-sity of extremophilic microbes. These organisms have evolved several structural and chemical adaptations, which allow them
to survive and grow in extreme en-vironments. The enzymes of these microbes, which function in extreme environments (extremozymes), have several
biotechnological applications. Antibiotics, compatible solutes and other compounds obtainable from these microbes are also finding a variety of uses.

Title: Biodiesel as a lubricity additive for ultra low sulfur diesel
Author: Subongkoj Topaiboul1 and 2,* ; Nuwong Chollacoop
Abstract: With the worldwide trend to reduce emission from diesel engines, ultra low sulfur diesel has been introduced with thesulfur concentration of
less than 10 ppm. Unfortunately, the desulfurization process inevitably reduces the lubricity of dieselfuel significantly. Alternatively, biodiesel, with
almost zero sulfur content, has been added to enhance lubricity in an ultralow sulfur diesel. This work has evaluated the effectiveness of the biodiesel
amount, sourced from palm and jatropha oil,and origin in ultra low sulfur diesel locally available in the market. Wear scar from a high-frequency
reciprocating rig isbenchmarked to the standard value (460 m) of diesel fuel lubricity. It was found that very small amount (less than 1%) ofbiodiesel
from either source significantly improves the lubricity in ultra low sulfur diesel, and the biodiesel from jatropha oilis a superior lubricity enhancer.
