Ethylbenzene + toluene are known individually to have ototoxic potential at high exposure levels and with prolonged exposure times generally of 4-16 weeks. Both ethylbenzene + toluene are minor constituents of JP-8 jet fuel; this fuel has recently been determined to promote susceptibility to noise-induced hearing loss. Therefore, the current study evaluates the ototoxic potential of combined ex...
DP803, an industrial catalyst used in petrochemical industry for dehydrogenation of isobutane to isobutene, was characterized in the current study. The results showed that zeolite Y is a high performance catalyst. This catalyst was then synthesized using a platinum source (hexachloro platinic acid) and two different tin sources (tributyl tin chloride and SnCl2.2H2O) all on zeolites Y, and then...
Kinetic isotopic effects (KIEs) for oxidative dehydrogenation of propane were measured on 10 wt% V2O5/ZrO2. Normal KIEs were obtained using CH3CH2CH3 and CD3CD2CD3 as reactants for primary dehydrogenation (2.8) and combustion (1.9) of propane and for secondary combustion of propene (2.6), suggesting that in all cases C–H bond dissociation is a kinetically relevant step. CH3CH2CH3 and CH3CD2CH3 ...
In this paper, cobaltporphyrin is used as a precursor to synthesize carbon nitrides with metal active sites supported on silica spheres by heat treatment (i.e. M-N-C/SiO2). The catalytic performance of M-N-C/SiO2 for ethylbenzene oxidation has been investigated and techniques such as N2 adsorption/desorption isotherm, NH3-TPD, HRTEM, STEM mapping and X-ray photoelectron spectroscopy (XPS) are e...
Expanded polystyrene (EPS) products and their associated chemicals (e.g., styrenes) are widespread in the marine environment. As a consequence, bans on their use for single-use packaging materials are being proposed in several municipalities. To better understand how science can inform decision-making, we looked at the available scientific literature about contamination and effects and conducte...
In the present study, a laboratory scale corn-cob based biofilter inoculated with pseudomonas fluorescents (mtcc 9768) was used for investigating the degradation of ethylbenzene and m-xylene for a period of 60 days in two phases. for ethylbenzene maximum removal efficiency (re) was 72% at an inlet concentration of 4.26 gm -3 and for m-xylene re was 76% at an inlet concentration of 6.39 g m -3 a...
