“…However, recent studies 22,23 of the different media used in this study, show the effectiveness of nickel oxide in the desulfurization by the number of adsorption of active sites, and also the decrease of an obstacle during the interaction with the particles of nickel atoms and sulfur present in the molecules saturated aromatic compounds, and presented a low cost.…”

“…Transition metallic oxides of the d-block are promising materials for the oxidative desulfurization process, however, their use is limited because of the specific superficial area, volume and small pore diameters 23,24 . The MCM-41 use as support for the nickel, palladium and titanium oxides enhanced the structural and textural properties of the oxides, promoting an increase in the contact area between the reactants (dibenzothiophene, hydrogen peroxide, molecular oxygen) and active phases (nickel, palladium and titanium oxides), responsible for the higher conversion of DBT.…”

Textural and catalytic properties of nickel, palladium or titanium oxides supported on MCM-41 materials were evaluated in this paper. The results indicated that the MCM-41 material with well defined and highly ordered hexagonal structure was obtained. After metal ions impregnation and calcinations, the structure of MCM-41 was preserved and formed metallic oxide particles, however the decreased of surface area of these structures occurred. The catalysts studied showed maximum conversion levels of dibenzothiophene in the range of 50-65%.

Zinc oxide (ZnO), with the unique chemical and physical properties of high chemical stability, broad radiation absorption range, high electrochemical coupling coefficient, and high photo-stability, is an attractive multifunctional material which has promoted great interest in many fields. What is more, its properties can be tuned by controllable synthesized morphologies. Therefore, after the success of the abundant morphology controllable synthesis, both the morphology-dependent ZnO properties and their related applications have been extensively investigated. This review concentrates on the properties of morphology-dependent ZnO and their applications in catalysis, mainly involved reactions on green energy and environmental issues, such as CO 2 hydrogenation to fuels, methanol steam reforming to generate H 2 , bio-diesel production, pollutant photo-degradation, etc. The impressive catalytic properties of ZnO are associated with morphology tuned specific microstructures, defects or abilities of electron transportation, etc. The main morphology-dependent promotion mechanisms are discussed and summarized.

“…A novel S-Zorb process for obtaining ultralow sulphur in transportation fuel was developed by Conoco Phillips Petroleum Co. in Houston, Texas, in the United State by reactive adsorption of sulphur heterocyclic compounds using a solid adsorbent at high temperatures and low hydrogen pressure. This was reported by Phillips Petroleum [93][94][95]. Reactive adsorption desulfurization utilizes the benefits of the adsorptive and HDS catalytic desulfurization, and therefore it is considered as an effective technique for deep desulfurization [96][97][98][99].…”

Sulfur oxide (SO 2 ) and hydrogen sulfide (H 2 S) are considered as one of the major air pollutants in the world today. In addition, high sulfur levels in petroleum distillates can promote the deactivation of catalysts through poisoning in fluidized catalytic cracking (FCC) during hydrocracking of the heavy distillates to lighter ones. The presence of high sulfur-containing compounds in the process streams could cause corrosion of piping and fittings and equipment, thereby damaging the pipelines and leading to air emissions of sulfur-containing compounds, which are undesirable for mankind and his environment. In many cases, a large quantity of SO x is released into the atmosphere when petroleum distillates that contain substantial amount of sulphur-containing compounds are used as fuel and combust. In this article, a short overview of different desulfurization methods that are employed to remove sulfur from petroleum distillates is provided. In particular, the review concentrates on biodesulfurization technique. In addition, this article intends to provide its readers current status of biodesulfurization (BDS). It critically analyses the trend in the development of the technology to showcase its strength and weakness that could pave a way for future opportunities. Approaches that are suitable to remediate sulfur-contaminated environment are discussed as well. Lastly, speculations on future directions or opportunities that require exploration are provided as a way of provoking the thoughts of researchers in this field.
