BTX compounds (Benzene, toluene and xylenes) are the main pollutants in air and fuels. Recent environmental legislations are limited the amount of these materials specially the amount of benzene in gasoline due to its carcinogen effects on health. In this research, the BTX hydrogenation was carried out using nanoparticles of Co supported on MWCNTs (multiwall carbon nanotubes) and AC (activated ...

in order to evaluate the adsorption potential of multi-walled carbon nanotubes (mwcnts) for benzene, toluene and xylenes (btx), the adsorption capacities of benzene and toluene on two different mwcnts were measured using a gas-chromatography (gc) and then compared with each other. fourier transform infrared (ftir) was employed to investigate the presence of functional groups on the carbon nanot...

BTX (benzene, ethylbenzene, toluene and p-xylene) and meteorological parameters were measured in ambient air of an urban site located in Carmen City, Campeche, Mexico. A total of 412 samples were collected for BTX and analyzed by Gas Chromatography with Flame Ionization Detection (GC-FID). Meteorological parameters were measured by a portable station. A marked diurnal variation was found for al...

In this research, gasoline vapours including Benzene, Toluene, Xylene (BTX) and Total Volatile Organic Compounds (TVOCs) emitted from vent pipes of underground storage tanks (USTs) were measured at six gas stations in Tehran. Thereafter, gas station No. 29 was selected as a pilot station and equipped with a vapour control system. The vapours were measured during the summer of 2013 and winter of...

Enrichment cultures obtained from soil exposed to benzene, toluene, and xylene (BTX) mineralized benzene and toluene but cometabolized only xylene isomers, forming polymeric residues. This observation prompted us to investigate the metabolism of 14C-labeled BTX hydrocarbons in soil, either individually or as mixtures. BTX-supplemented soil was incubated aerobically for up to 4 weeks in a sealed...

This paper mainly focuses on treatment process for Benzene, Toluene & Xylene (BTX) containing wastewater by using an alternating anoxic/micro aerobic sequencing batch reactor to overcome the stripping of BTX compounds into the atmosphere, as often occurs in conventional aerobic treatment processes. An ORP probe was successfully used to monitor different electron acceptor conditions in sequencin...
