“…The maximum adsorption capacity could reach as high as 86 mg S g −1 . It worth noting that the high adsorption capacity of the as-prepared porous BN microfibers for DBT (measured value for 41.59 mg S g −1 and theoretical value for 86 mg S g −1 ) can not only surpass those of transitional adsorbents such as zeolite (10.9 mg S g −1 ) 34 , mesoporous silica (3 mg S g −1 ) 35 , activated alumina (16.6 mg S g −1 ) 36 , metal-organic frameworks (MOFs) (12 mg S g −1 ) 37 , activated carbon (10.39 mg S g −1 ) 38 , but also rival those of many newly reported adsorbents, i.e. C-doped BN (35.2 mg S g −1 ) 26 , suggesting an excellent adsorptive desulfurization performance of the porous BN microfibers.Figure 7Langmuir isotherm of DBT adsorption porous BN fibers.

We report on the controllable synthesis of porous BN microfibers and explore their applications as adsorbent for removing dibenzothiophene (DBT) in model oil. The growth evolution of porous BN microfibers has been carefully investigated by correlating their structural characteristics with their synthesis conditions. The as-prepared BN microfibers exhibit very high adsorption capacity for DBT (86 mg S g−1 according to the Langmuir isotherm model), showing excellent adsorptive desulfurization performance. The porous BN after adsorption can be regenerated by a simply heat treatment. After four times recycling, the regenerated adsorption capacity still remains more than 83% of that at the first adsorption. The superb oxidation resistance and chemical inertness, high sulfur adsorption capacity, as well as excellent regeneration performance render the developed porous BN microfibers to be a decent adsorbent for sulfur removal from fuels.

“…The adsorbents facilitated rapid binding of DBT. However, the strong interaction of activated carbon with DBT decreased desorption of DBT from the adsorbent causing problems in subsequent regeneration of the adsorbent [134].…”
“…Li et.al. studied integrated adsorption and microbial methods for desulphurization of diesel [33].They observed that the integrated method was able to remove sulphur more efficiently than other methods. Turgman-Cohen et.al.…”
Section: Research On Adsorption In Petroleum Industries and Refineriesmentioning
Adsorption finds application in reaction engineering, environmental engineering and petrochemical engineering. Removal of many components of flue gases can be carried out by adsorption. The research on removal of heavy metals, dyes has also been carried out by number of investigators. The studies on batch adsorption mainly include isotherm, kinetics and effect of various parameters. In petrochemical industries, the catalyzed reactions involve adsorption. Also the recovery of oil from wastewater can be carried out by adsorption. The removal of sulphur or desulphurization also can be carried out by adsorption. Removal of various pollutants from flue gases and wastewater can be carried out by adsorption. The present review summarizes the research carried out on adsorption related to its application in petrochemical and refining industries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
