Abstract In the present study, simultaneous removal of the dibenzothiophene (an aromatic refractory sulfur compound) and quinoline (an aromatic refractory nitrogenous compound) from model fuel was performed using the zinc impregnated granular activated carbon (Zn-GAC). Textual properties of the adsorbent were determined by liquid nitrogen adsorption technique. Binary isotherm study revealed that the quinoline adsorption onto Zn-GAC was more favored in comparison to dibenzothiophene. Various multi-component isotherm models were used for representing the isotherm data from binary solution. Modified Redlich-Peterson model best represented the isotherm data.

Activated carbon (AC) was pretreated by H2O2 or HNO3 and then loaded with cerium to obtain Ce/AC composites as desulfurization adsorbents. The adsorption isotherms of as-prepared Ce/AC composites for dibenzothiophene were measured in static batch desulfurization of model fuel and compared with the one prepared without AC pretreatment. It was found that both H2O2 and HNO3 pretreatment could enhance the adsorption capacity of Ce/AC composites. The results were discussed in terms of surface chemistry and texture property. The improvement could be related to increased surface acidic groups and better dispersion of loaded metal species bought about by the two pretreatment methods

In this study, a portable and disposable paper-based microbial fuel cell (MFC) was fabricated. The MFC was powered by Rhodopseudomonas palustris bacteria (R. palustris). An activated carbon sheet-based anode pre-loaded organic matter (starch) and R. palustris was used. By using starch in the anode, R. palustris-loaded on the anode could be preserved for a long time in dry conditions. The MFC could generate electricity on-demand activated by adding water to the anode. The activated carbon sheet anode was treated by UV-ozone treatment to remove impurities and to improve its hydrophilicity before being loaded with R. palustris. The developed MFC could generate the maximum power density of 0.9 μW/cm2 and could be preserved for long-term usage with little performance degradation (10% after four weeks).
