The esterification of oleic acid with short-chain alcohols using Brønsted acidic ionic liquid supported onto Fe-incorporated SBA-15 (Fe-SBA-15) was studied to develop a green method for biodiesel production. This catalyst prepared by immobilization 1-(propyl-3-sulfonate)-3-(3-trimethoxysilylpropyl) imidazolium hydrogen sulfate ([SO3H-PIm-CPMS][HSO4]) Fe-SBA-15 (IL/Fe-SBA-15). structure the characterized XRD, N2 adsorption–desorption measurement, FT-IR and TEM. results demonstrated that Fe...
The KNO<sub>3</sub> supported on 3DOM La<sub>0.8</sub>Ce<sub>0.2</sub>Mn<sub>1−x</sub>Fe<sub>x</sub>O<sub>3</sub> perovskites have been prepared and used for soot removal. presence of potassium nitrate can accelerate the combustion at both low high temperature. catalysts exhibit activities combustion.
Hexagonal hollow carbon nitride with vacancies improves the harvesting capability of visible light, separation rate photo-induced carriers and adsorption capacity reaction substrate.
Improving the accessible reaction sites of catalysts is vital to diesel soot elimination. Herein, hierarchical brushlike α-MnO2 and Co3O4 nanoarrays were in situ grown on AISI304 stainless steel wire-mesh via a two-step hydrothermal method. Morphology investigation displayed that compared with sole or nanoarrays, provided 8-fold sites. XRD, Raman spectroscopy, XPS, H2-TPR, soot-TPR techniques proved synergistic effect between cobalt manganese, namely, weaker Mn–O bonds, more surface active...
The addition of Ce into Cr-based perovskite restrained the growth crystal size and delayed transformation from LaCrO<sub>4</sub> to LaCrO<sub>3</sub>, thus, 3DOM structure was maintained even after calcination at 800 °C.
MnO<sub>2</sub> nanocomposites with porous structure were successfully synthesized by a facile hydrothermal route from KMnO<sub>4</sub> without the addition of any acid.
Production of alternative, clean aviation fuel from biomass synthesis gas via Fischer–Tropsch (FT) has attracted much attention. In this paper, Al-SBA-15 supported cobalt catalysts with different Al/Si ratios were successfully prepared for the production by FT synthesis. The physical and acidic properties Co/Al-SBA-15 characterized XRF, XRD, N2 adsorption–desorption, TEM, H2-TPR, 27Al NMR, NH3-TPD, Py-FTIR. formation long-chain hydrocarbons was inhibited ordered mesoporous structure....
The reaction kinetics of the transesterification methyl acetate with n-propanol is described by pseudohomogeneous (PH) kinetic model, which can successfully correlate experimental data. influence temperature as well catalyst loading and initial molar ratio to on this studied under condition eliminating both internal external mass transfer resistances. On basis PH influences design parameters are studied, such recycle flow rate, number stages reactive distillation column (RD), theoretical...

Abstract While fluorescence‐based high‐throughput screening (HTS) has been valuable for identifying enzymes and microorganisms polyethylene terephthalate (PET) depolymerization, the traditional approach relies on cleaving ester bonds in small‐molecule probes, limiting its ability to directly detect activity towards polymeric PET substrates. This study proposes a novel strategy detecting release of sulfhydryl groups during depolymerization pseudo‐PET polythioesters by polyester hydrolases....

The requires only side draw organic reflux to tray temperatures column, bottom heating...
Fluorescence-based high-throughput screening approaches facilitate the discovery of enzymes and microorganisms for polyethylene terephthalate (PET) depolymerization recycling. However, traditional method activating fluorescence signal by cleaving ester bond on small molecule probes has limited ability in detecting enzymatic activity towards polymeric substrates. This study proposes a novel fluorescence-based strategy that detects release sulfhydryl groups during pseudo-PET polythioesters...
Isobaric binary vapor–liquid equilibrium (VLE) data for ethylbenzene + ethyl benzoate, o-xylene m-xylene and p-xylene as well the quinary VLE benzoate ethylbenzene, were measured at 101.33 kPa using a modified Rose still.
