“…Zhang et al have studied the effect of ZnO particle size in a Ni/ZnO adsorbent in a reactive desulfurization of fuels . Wang et al claimed that in a desulfurization methodology that involved the alumina membranes coupled with fixed bed adsorption sulfur levels in a jet fuel are reduced to 10 ppm . In a study by the Tian et al, a cerium modified beta zeolite with different silica to alumina ratios was used for desulfurization .…”

Adsorptive desulfurization of a model diesel fuel consisting of dibenzothiophene (DBT) or 4,6‐dimethyldibenzothiophene(4,6‐DMDBT) in hexadecane was performed over activated carbons and tantalum oxide modified (Ta‐x/ACC, x= 2, 5 or 10 wt % Ta, Activated Carbon Centaur) activated carbons at 50°C. The adsorption isotherm for ACC followed the Langmuir model while the adsorption on Ta‐5/ACC fitted the Sips equation indicating more than one type of adsorption sites. Characterization studies indicated new types of adsorption site resulting from the incorporation of Ta oxide into the porous structure of the ACC. XPS data suggested interaction of Ta with the S atom in DBT. The heats of adsorption in the liquid phase determined from micro flow calorimetry for DBT in C16 confirmed the interaction of Ta with DBT. Ta‐5/ACC exhibited the highest adsorption capacity for 4,6‐DMDBT compared to literature reports. Competitive adsorption experiments showed the adsorption capacity as follows: quinoline> DBT≫ naphthalene. © 2017 American Institute of Chemical Engineers AIChE J, 2017

“…Nowadays, environmental concerns have resulted in legislation which places limits on the sulphur content of gasoline . Accordingly, a number of solutions have been suggested to reduce sulphur in gasoline, such as hydrotreating, adsorption, and extraction . However, they all have their own shortcomings, so researchers have been constantly exploring new alternative technologies.…”

Polyethylene glycol (PEG) of three different molecular weights was used to prepare PEG/PVDF composite membranes for separating organosulphur compounds from n‐heptane by pervaporation. All the composite membranes were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X‐ray diffraction (XRD), and positron annihilation spectroscopy (PAS). The effects of operating temperature, feed sulphur content, and organosulphur species on performance of PEG/PVDF composite membranes with different molecular weights were investigated. When the feed organosulphur was thiophene, the fluxes decreased with an increase in PEG molecular weight, however, the enrichment factors were in a different order: PEG membrane with molecular weight of 35 000 exhibited the highest enrichment factor of 12.59 for thiophene at 85 °C. When the feed organosulphur was 2‐methylthiophene or 2,5‐dimethylthiophene, it was found that the PEG membrane with molecular weight of 100 000 showed the highest enrichment factor. The results showed that PEG molecular weight has a considerable effect on separation performance for pervaporation desulphurization.

“…Behavior of SOFCs has been studied by different researchers using both simulation models as well as experiments [2][3][4][5][6][7][8][9]. Primary focus of numerical simulations is on analysis of fuel cells without putting much emphasis on formal optimization procedures or sensitivity computation.…”

“…Desulfurization methods suitable for portable applications without reducing the fuel octane number have been studied in recent years, and two of the promising processes were pervaporation [2][3][4] and selective adsorption [5][6][7][8]. The latter is considered the most promising method [1].…”

AbstractA three-dimensional, unstructured, multi-species reacting flow solver is developed to model solid oxide fuel cells (SOFCs) as well as catalytic reactors. The finite volume based solver utilizes density-based method to solve the coupled system of governing equations. Numerical results for both SOFC and reactor obtained using the inhouse code are compared with the experimental results from the literature for validation purposes. Effects of mass flow rates of incoming species on performance of SOFC as well as catalytic reactor are investigated. Two different methods namely direct differentiation and discrete adjoint method are implemented in the code to compute sensitiv...
