Zeolite synthesis from industrial wastes
(Elsevier, 2019)
info:eu-repo/semantics/article,
Conventional synthesis conditions for each type of zeolite are tabulated and reported by the International Zeolite Association Structure Commission (IZA) and most of them are synthesized from commercial reagents, but they ...
Optimizing the removal of nitrate by adsorption onto activated carbon using response surface methodology based on the central composite design
(Taylor & Francis, 2020)
info:eu-repo/semantics/article,
This study sheds light on the adsorption process for the removal of nitrate ions from synthetic aqueous solutions. This contaminant pose a potential risk to the environment and can cause health effects including cancers ...
A comparative study of the catalytic performance of nickel supported on a hibonite-type La-hexaaluminate synthesized from aluminum saline slags in the dry reforming of methane
(Elsevier, 2022)
Artículo / Artikulua,
In this work, a hibonite-type Ni/La-hexaaluminate (Ni/LHA) synthesized from an industrial
waste is used and compared as catalyst in the dry reforming of methane (DRM) at 973 K.
The structure, catalytic behavior, and ...
Progress in the synthesis and applications of hexaaluminate-based catalysts
(Taylor & Francis, 2020)
info:eu-repo/semantics/article,
The development of materials that can exhibit thermal resistance at very high temperatures, thus allowing them to be applied as catalysts and thermal insulators, amongst other possible uses, is a research subject of great ...
Layered double hydroxides for CO2 adsorption at moderate temperatures: synthesis and amelioration strategies
(Elsevier, 2023)
Artículo / Artikulua,
Curving the CO2 atmospheric levels is one of the challenges of this century, given its direct impact on climate
change. Of the several strategies of CO2 capture and storage, sorption-enhanced water–gas shift (SEWGS) ...
Effect of high pressure on the reducibility and dispersion of the active phase of Fischer-Tropsch catalysts
(MDPI, 2019)
info:eu-repo/semantics/article,
The effect of high pressure on the reducibility and dispersion of oxides of Co and Fe supported on -Al2O3, SiO2, and TiO2 has been studied. The catalysts, having a nominal metal content of 10 wt.%, were prepared by incipient ...
Recent progress in the application of Ni-based catalysts for the dry reforming of methane
(Taylor & Francis, 2021)
info:eu-repo/semantics/article,
Ni-based catalysts are highly efficient in methane-reforming processes. In the particular case of methane reforming in the presence of carbon dioxide, or dry reforming of methane (DRM), it is necessary to modify and control ...
Evidence for the synthesis of La-hexaaluminate from aluminum-containing saline slag wastes: correction of structural defects and phase purification at low temperature
(Elsevier, 2021)
info:eu-repo/semantics/article,
The synthesis of a lanthanum hexaaluminate from the aluminum extracted from a saline slag waste is presented for the first time. Briefly, a refluxing 2 M solution of HCl is used to extract the aluminum, giving 8.9 gAl/dm3 ...
Zeolite synthesis from aluminum saline slag waste
(Elsevier, 2020)
info:eu-repo/semantics/article,
This work describes the synthetic procedures developed to obtain zeolite X (NaX), zeolite A (LTA) and sodalite (SOD) using aluminum saline slag waste (AlSSW) as aluminum source in a two-step hydrothermal method involving ...
Adsorption recovery of Ag(I) and Au(III) from an electronics industry wastewater on a clay mineral composite
(University of Science and Technology BeijingSpringer, 2019)
info:eu-repo/semantics/article,
The aim of this work is to investigate the ability of an adsorbent of a clay mineral composite to remove and recover gold and silver ions from wastewater. The composite was prepared by mixing phosphogypsum (PG), obtained ...
