Boosting the hydrodesulfurization of dibenzothiophene efficiency of Mn decorated (Co/Ni)-Mo/Al2O3 catalysts at mild temperature and pressure by coupling with phosphonium based ionic liquids

Photocatalytic oxidative degradation of hydrocarbon pollutants in refinery wastewater using TiO2 as catalyst

“…Low concentrations of cyclic aliphatic hydrocarbons such as 2-methylbutyl cyclopentane and 1-octylnonyl cyclohexane were also present. These findings are in accordance with the reported literature (Muhammad et al, 2019;Stepnowski, Siedlecka, Behrend, & Jastorff, 2002).…”

“…At 100 mg/L dose of TiO 2 , the degradation of benzene, toluene, phenol, and naphthalene reached 43.5, 42.1, 45.8, and 44.6%, respectively. The increasing hydrocarbon degradation with increasing catalyst dose could be ascribed to availability of greater number of active sites on the catalyst surface (Muhammad et al., 2019; Subhan et al., 2019). Thus, higher catalyst dose facilitates the production of a greater yield of • OH (Kumar & Pandey, 2017).…”

“…TiO 2 is a preferred catalyst attributed to its high activity, easy availability, cost‐effectiveness, and convenient recovery from the treated wastewater (Abdelwahab, Amin, & El‐Ashtoukhy, 2009). UV/TiO 2 photocatalytic oxidation system has shown high degradation activity for a wide range of organic pollutants (Muhammad et al., 2019; Javad Saien & Shahrezaei, 2012; Santos et al., 2006) and, thus, can be a good choice of the photocatalytic degradation of hydrocarbons in refinery wastewater.…”

Assessing the Aflatoxins Mitigation Efficacy of Blueberry Pomace Biosorbent in Buffer, Gastrointestinal Fluids and Model Wine

“…The chemistry and functional group characterization of the prepared adsorbents were achieved by FTIR using Thermo Fisher Scientific Nicolet 6700 instrument (Thermo Fisher Scientific, Waltham, MA, US) in a range of 400–4000 cm −1 following the KBr disc method [ 68 , 69 , 70 ]. Surface morphology, particle shape and distribution of adsorbent materials were studied by SEM (Hitachi high-technologies corporation, Tokyo, Japan, SU8220, S-3400N) by gold coating the samples prior to analysis.…”

Non-Catalytic Oxidative Desulfurization of Diesel Oil Using Ozone in a Biphasic Oil/Acetonitrile System

“…Removal of organosulfur in liquid hydrocarbon fuel has become an important subject worldwide because SO x generated upon combustion of sulfur-containing diesel fuel leads to the formation of acid rain, and also the emission of harmful particulate matter in vehicle exhaust Muhammad et al, 2019a). The existing hydrodesulfurization (HDS) process is effective for the removal of thiols, sulfides, and disulfides, but has difficulty removing refractory benzothiophenic and dibenzothiophenic compounds in diesel due to steric hindrance Yaseen et al, 2012;Dai et al, 2014;Muhammad et al, 2019b). Thus, the development of a non-HDS process for deep desulfurization is highly desirable.…”
