Keeping in view the growing concern regarding desulphurization of petroleum products, the present study was under taken to investigate the efficiency of tin impregnated activated charcoal (Sn-AC) as a potential adsorbent for the desulphurization of model and real commercial straight run kerosene and diesel oil samples. The adsorbent Sn-AC was prepared by wet impregnation process in the laboratory and characterized by SEM, EDX and surface area analysis. Initial experiments were carried out using model oil, which was prepared by dissolving dibenzothiophene (DBT) in cyclohexane, the optimum conditions for desulfurization were found to be, 60°C temperature, 1h contact time and adsorbent dosage of 0.8g, under which about 99.4% of DBT removal was attained. Under optimized conditions the desulfurization of real oil i.e., kerosene and diesel oil was also investigated. Kinetic studies revealed that DBT adsorption followed pseudo second order kinetics and the data best fits in the Langmuir adsorption isotherm as compared to Freundlich adsorption isotherm model. The adsorbent could be easily regenerated simply by washing with toluene for a multiple cycles and reused without losing its efficiency.

The heterogeneous photocatalytic desulfurization processes have been paid wide attention due to their effectiveness in removing the condensed organo-sulfur compounds. Such methods may gain greater consideration via utilizing the visible light in general and sun spectrum in particular. This research work aims to produce low sulfur diesel fuel through a catalyzed photochemical route using nanoparticles of CdO under the visible-light irradiation. Two various structures of CdO were prepared in this study by both the chemical precipitation and autoignition techniques. The structural and morphological characteristics of the obtained cadmium oxides were determined via different tools of analyzes. The production of a low sulfur diesel fuel was then investigated under various operating parameters, such as type of light source, catalyst-to-feed dosage, and reaction time. The effect of adding oxidizing agents at different concentrations on the desulfurization process was also studied. After the maximum sulfur removal had been detected under the optimum conditions, the ultimate removal of sulfur was attained through a subsequent solvent extraction step. A diesel fuel with a sulfur content of 45 ppm was acquired at the end of this research study. A total sulfur removal of 99.6 wt % was obtained because the original diesel fuel feedstock has an overall concentration of the sulfur compounds of 11 500 ppm.

“…It should also be noticed that effects of impurities in such waste on the synthesis of CNPs would be of concern so that many current strategies have been explored by adapting from some existing technologies. For example, the bottom product of a crude distillation unit in a petroleum refinery process usually contains high contents of sulfur and mercury compounds (Mohammed et al, 2012;Zubaidy et al, 2013;Khairi et al, 2015). Typically, various methods including chemical adsorption, gas stripping and chemical precipitation are employed for removing mercury from crudes and other hydrocarbon liquids to avoid the problems of poisoning.…”

An increase in global consumption has led to an exponential increase in industrial production activities which inevitably results in overwhelming remain of industrial waste. Consequently it has driven increasing attentions of research and development teams in various countries to propose and investigate novel methodologies to utilize such industrial waste. Instead of using as alternative energy sources, usage of industrial waste for production of carbonaceous nanomaterials has been examined via various routes, such as catalytic pyrolysis, hydrothermal treatment and so on. Meanwhile, for sustainable and secure continuity of the carbonaceous nanomaterial production, broad spectra of promising applications have also been examined. Among those emerging applications, utilization of carbonaceous nanomaterials in pollution control and prevention has been focused worldwide. Therefore, in this review, relevant research works focusing on catalytic pyrolysis of carbonaceous industrial waste for carbonaceous nanomaterial production were comprehensively analyzed and summarized. In addition, promising applications involving with antibiotic removal, spilled oil handling and pollutant gas detection were also reviewed.
