“…Several types of adsorbents based on activated carbons and their modified forms as well as carbon cloths [18,19], zeolites and their metal-loaded derivatives [20,21], transition metals supported on porous materials [11,13], adsorbents based on mesoporous silica, alumina and zirconia, and their metal-loaded derivatives [22][23][24] have been developed and used for the adsorptive desulfurization of various fuels with low energy consumption at ambient conditions [25]. Ordered mesoporous carbons, among different adsorbents, are promising materials for adsorption of various compounds due their unique properties such as regular mesoporous pore structure, narrow pore size distribution, large specific surface area, as well as excellent chemical and physical stabilities [26,27].…”

A B S T R A C TThe aim of this study was to optimize the conditions of the Basic Blue 41 (BB41) adsorption on NaOH-modified rice husk (NaOH-RH) using response surface methodology based on Box-Behnken design. The three-level factors considered were pH (4, 7, and 10), initial concentration of BB41 (50, 75, and 100 mg L −1 ), and adsorbent dose (0.025, 0.0875, and 0.15 g L −1 ). Statistical analysis of result has shown that the predicted values for BB41 adsorption were close to the experimental values and were in a good agreement, on the other hand, the F-value (40.48), p-value (0.0004), and R 2 (0.9865) indicated that the regression is able to give a good prediction of response for the adsorption process in the range studied. According to the results, when the response was set in maximize and all the three factors were set in a range, the optimized values for BB41 adsorption were predicted as follows: pH value of 8.47, and BB41 initial concentration of 67.9 mg L −1 and adsorbent dose of 0.12 g L −1 for removal efficiency of 97.65%.

“…The higher adsorption capacity and selectivity on ACs for the DBTs with one or two alkyl groups at the 4 and/or 6 positions, which are difficult to remove by HDS and other adsorbents, have attracted many researchers; thus, ACs from different kinds of resources, such as coal (Shalaby et al 2009), polymer ), rice hull (Kumagai et al 2009, Yu et al 2013b, and dates' stone (Alhamed and Bamufleh 2009), have been prepared for deep desulfurization from diesel in recent years. Song and coworkers (Shalaby et al 2009) reported that high-performance organic sulfur adsorbents (OSAs) have been developed from coal by chemical activation for selective adsorption of DBTs, such as 4-MDBT and 4,6-DMDBT, in diesel fuel.…”

AbstractRemoval of organic sulfur compounds from diesel by adsorption on different carbon materials, including activated carbons (ACs), carbon aerogels, carbon nanotubes, and AC cloths, was reviewed. The effect of the textural and surface chemistry property of carbon on desulfurization performance, carbon surface modification, adsorption mechanism, and adsorbent regeneration and the effect of other components, including aromatics, additives, nitrogen compounds, and moisture, on adsorptive desulfurization of diesel fuel were also discussed in detail. Carbon materials showed very high selectivity for removing the dibenzothiophenes, especially for 4,6-dimethyldibenzothiophene, which is very difficult with hydrodesulfurization and other adsorbents. Both the textural and chemical properties of AC have an important impact on the adsorption of DBTs. Adsorption selectivity and capacity can be enhanced further by carbon surface modification. Considering the effect of diffusion hindrance and regeneration, mesoporous carbon is more suitable than microporous carbon with pore size <2 nm. It is necessary to eliminate the inhibiting effect of fuel additive and nitrogen compounds on the DBTs before carbon materials are used for desulfurization of real diesel fuel. In the end, some useful suggestions are also made.
