The study of water–hydrocarbon phase equilibria is very important for both scientific and industrial purposes. This work a thorough investigation the predictive capability SAFT-VR Mie equation state (EoS) aqueous hydrocarbon equilibria, including n-alkanes, alkenes, cycloalkanes, branched alkanes, aromatic hydrocarbons. For alkenes alkyl benzenes, induced association (solvation) with water cons...

Catalyst is the key for hydrodeoxygenation (HDO) of lignin derivatives to produce alkyl aromatics and cycloalkanes, components 100% sustainable aviation fuels (SAF). Mono bi-functional catalysts nickel (Ni) heterophosphotungstic acid (HPW) supported on SBA-15 carbons were prepared, characterized evaluated HDO derived trans-anethole. The structure was intact but its surface area pore volume decr...

Indoor volatile organic compounds (VOCs) may be associated with adverse health effects. The aim of this study was to investigate whether the indoor VOCs exposure burden has undergone changes during a past 15-year period, exemplarily in a German city. The study was limited to homes with families. To avoid possible regional-specific confounder effects, this assessment was conducted for this urban...

Total petroleum hydrocarbon (TPH) is a complex mixture of hydrocarbons including saturate fraction such as n-alkanes, branched alkanes, and cycloalkanes (naphthenes). TPH is normally come from the accidental leakage of storage tanks of lubricating and fuel oils resulting in the soil contamination. TPH is classified as the hazardous material and is considered as the most organic pollutants in th...

Heterogeneous metal complex catalysts for direct C–H activation with high activity and durability have always been desired for transforming raw materials into feedstock chemicals. This study described the design and synthesis of one-dimensional organosilica nanotubes containing 2,20-bipyridine (bpy) ligands in the framework (BPy-NT) and their post-synthetic metalation to provide highly active a...

Anaerobic microbial hydrocarbon degradation is a major biogeochemical process at marine seeps. Here we studied the response of the microbial community to petroleum seepage simulated for 190 days in a sediment core from the Caspian Sea using a sediment-oil-flow-through (SOFT) system. Untreated (without simulated petroleum seepage) and SOFT sediment microbial communities shared 43% bacterial genu...

The activity coefficients at infinite dilution, c13, of 55 organic solutes and water in three ionic liquids with the common cation 1-butyl-3-methylimidazolium and the polar anions Cl , [CH3SO3] and [(CH3)2PO4] , were determined by (gas + liquid) chromatography at four temperatures in the range (358.15 to 388.15) K for alcohols and water, and T = (398.15 to 428.15) K for the other organic solute...

New data of activity coefficients at infinite dilution, γ13∞, for 65 different solutes including alkanes, alkenes, alkynes, cycloalkanes, aromatic hydrocarbons, alcohols, thiophene, ethers, ketones, aldehydes, esters and water in the ionic liquid 1-ethyl-3-methylimidazolium trifluorotris(perfluoroethyl)phosphate, were determined using inverse gas chromatography within the temperature range from...
