Abstract The adsorption excess isotherms of ethanol–water and propanol–water mixtures are studied on a series carbon molecular sieves with well-separated micro- mesoporosity at 298.15 K. preferential one component from mixture is measured by using vibration densitometry for the concentration analysis. Microcalorimetrically enthalpies, which released upon immersion materials in binary mixtures, ...

The synthesis of transition metal oxides is typically time- and energy-consuming. Recently, fast sintering methods have demonstrated great potential in reducing ceramic time energy use, improving the commercial prospects these materials. In this article, a quenched ultrafast high-temperature (qUHS) technique developed to sinter metastable brownmillerite SrCoO2.5 (SCO) less than minute. Surprisi...

Crude bio-oil from fast pyrolysis of biomass has a high oxygen content and acidity, leading to problems with corrosion polymerization/instability. In this work, the catalytic vapor phase upgrading acetol, compound that is present in concentrations vapors, was investigated over three microporous HZSM-5 four mesoporous catalysts different levels acidity mesoporosity. All were steam-treated prior ...

To assess how the grain size/rock fabric of laboratory-matured shale samples impact oil, gas production, and formation pores during laboratory thermal maturation, cores (4.5 mm*1 cm) bulk rock, millimetric equidimensional rock fragments (3*3 mm), fine grind powder (<200 μm) were obtained from an organic-rich mudstone (Kimmeridge Clay Fm. “KCF”, Yorkshire, UK) artificially matured under anhydrou...

MOF-derived carbon-based materials have attracted widespread attention due to their relatively large surface area, morphology, and stability in water. Considering these advantages, present themselves as excellent adsorbents. In this work, a novel method was designed for the fabrication of nano zero-valent-iron (nZVI) carbon composite. The utilization zinc oxide nanorods (ZnONRs) role sacrificia...

Enhanced SO2 adsorption of activated carbon fibers is obtained by tailoring a specific micro-mesoporous structure in the fibers. This architecture is obtained via metal catalytic activation of the fibers with a novel precursor, cobalt naphthenate, which contrary to other precursors, also enhances spinnability and carbon fiber yield. In the SO2 oxidation, it is demonstrated that the combination ...

A set of hierarchical beta zeolites with variable Si/Al ratios, nanoparticle sizes, textural and acidic properties was prepared using a hydrothermal treatment concentrated alkali metal-free protic acid-containing zeolite gel-precursor. The obtained catalysts were investigated in the Prins cyclization isovaleraldehyde isoprenol yielding commercially valuable tetrahydropyranol (Florol). highest y...

This study presents the effects of different activation methods to produce activated carbon from hydrolysis lignin. Pretreatment feedstock with common mineral acids (HCL, HNO3, and H3PO4), steam rates for physical activation, chemical activating agents (ZnCl2, Na2CO3, KOH) were investigated. The pretreated biomass was carbonized in one-stage process surface characteristics, such as total pore v...
