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 ...
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 ...
Feasibility to producing second generation bioethanol in Bolivia
(Universidad Nacional del Sur (Argentina), 2021)
info:eu-repo/semantics/article,
Bioethanol produced worldwide is mostly obtained from agricultural crops such as sugarcane and corn. However, it has negative environmental effects, so opportunity for producing bioethanol from agricultural waste arises. ...
Progress and recent strategies in the synthesis and catalytic applications of perovskites based on lanthanum and aluminum
(MDPI, 2022)
Artículo / Artikulua,
Lanthanum aluminate-based perovskite (LaAlO3) has excellent stability at high temperatures, low toxicity, and high chemical resistance and also offers wide versatility to the substitution of La3+ and Al3+, thus, allowing ...
A layered titanosilicate AM-4 as a novel catalyst for the synthesis of 1-methoxy-2-propanole from propylene oxide and methanol
(Elsevier, 2019)
info:eu-repo/semantics/article,
In this paper we report for the first time the catalytic properties of the titanosilicate AM-4 in the synthesis of 1-methoxy-2-propanol (PGME) from methanol and propylene oxide (PO). PGME is widely used as a pollution-free ...
White and red Brazilian Sao Simao's kaolinite-TiO2 nanocomposites as catalysts for toluene photodegradation from aqueous solutions
(MDPI, 2019)
info:eu-repo/semantics/article,
The presence of volatile organic compounds in groundwater is a major concern when it is used as a drinking water source because many of these compounds can adversely affect human health. This work reports on the preparation ...
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 ...
Separación electrostática de una emulsión de glicerina en biodiésel con aplicación de varios voltajes y distancias entre electrodos
(Centro de Información Tecnológica, 2019)
info:eu-repo/semantics/article,
Con el propósito de aplicar una tecnología limpia y de bajo consumo energético en la separación de emulsiones, se construyó un separador electrostático de 1,0 dm3. Se utilizaron electrodos de cobre rectangulares. Para los ...
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) ...
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 ...
