Presumptive representation structure of the prepared cross-linked nanocomposite proton exchange membrane.
In this work, novel proton-exchange membranes (PEMs) based on sulfonated poly(ether ether ketone) (SPEEK) and two-dimensional (2D) niobium disulphide (S-NbS2) nanoflakes are synthesized by a solution-casting method used in vanadium redox flow batteries (VRFBs). The NbS2 produced liquid-phase exfoliation of their bulk counterpart chemically functionalized with terminal sulfonate groups to improve dimensional chemical stabilities, proton conductivity (σ) fuel barrier properties the as-produced...
The inhibition effects of several chemical additives on asphaltene precipitation were investigated by the microscopic method. consist a synthesized deep eutectic solvent (SDES), commercial inhibitor, and three surfactants, namely lauric acid, octyl phenol, dodecyl amine. results showed phenol with 500 mg/L concentration is similar to inhibitor later SDES had maximum delaying onset point. mean particle size using SDES, amine decreased about 55%, 41%, 24%, 18%, respectively, compared oil...
A novel, high-efficiency, and cost-effective series of sulfonated poly(phthalazinone ether ketone)/sulfonated titanium dioxide@toluene diisocyanate@ethylenediamine (SO3H−TiO2@TDI@EN-SO3H) nanocomposite membranes is designed to enhance the proton conductivity methanol barrier exchange membrane (PEM). The were prepared via a facile one-step process solution casting method. presence organic–inorganic SO3H–TiO2@TDI@EN-SO3H nanoparticles improved performance in terms mechanical stability,...
Zeolite beta nanoparticles were used as a new asphaltene adsorbent for reducing deposition during fluid injection into silica sand pack. At first, the adsorption efficiency and capacity of zeolite determined by UV-Vis spectrophotometer. It was found that proper concentration 10 g/L maximum onto 1.98 mg/m 2 . Second, two dynamic experiments including co-injection crude oil n-heptane (as an precipitant) with without use in pack carried out. The results showed increased permeability ratio...
In this work, the natural depletion process in sandstone and carbonate cores was modeled to investigate asphaltene deposition mechanisms. A new permeability reduction correlation proposed based on Minssieux model that considers a combination of surface deposition, pore throat plugging, filtration cake The results showed is dominant mechanism during both core samples. Therefore, modified with adding formation due filling Wang Civan model. absolute average deviation (AAD (%)) for between three...
