Evaluation of KHSO4 as a recyclable catalyst in the production of dehydrated castor oil to be applied in alkyd resins
(Elsevier, 2021-12)
Due to its lower solubility, this work proposes the use of KHSO4 as a re-usable heterogeneous catalyst in the dehydration of castor oil. Refined and degummed castor oil were considered to determine the effect of the ...
Selective ring opening of methylcyclohexane and decalin over Rh-Pd supported catalysts: Effect of the preparation method
(Elsevier, 2015-12)
Bimetallic Rh-Pd catalysts prepared by various impregnation methods were evaluated in the selective ring-opening of decalin and methylcyclohexane (MCH) used as model molecules of hydrogenated aromatics of the Light Cycle ...
Metathesis of methyl oleate over rhenium oxide-based catalysts supported on borated silica-alumina: catalyst recycling
(Elsevier Science BvAmsterdamHolanda, 2004)
MgAl2O4 spinel prepared by novel mechanochemical synthesis used as a support of multimetallic catalysts for paraffin dehydrogenation
(Pleiades Publishing, 2013-01)
The catalytic performance in nbutane dehydrogenation of bimetallic PtSn, PtGa and PtIn, and tri metallic PtSnIn and PtSnGa catalysts (with low metal contents) supported on a MgAl2O4 prepared by a novel mechanochemical ...
Sulfur Resistance of Pt-W catalyst
(Hindawi Publishing Corporation, 2013-01)
The sulfur resistance of low-loaded monometallic Pt catalysts and bimetallic Pt-W catalysts during the partial selective hydrogenation of styrene, a model compound of PYGAS streams, was studied. The effect of metal ...
Simultaneous solidification of two catalyst wastes and their effect on the early stages of cement hydration
(Springer, 2011-08-01)
Two catalyst wastes (RNi and RAI) from polyol production were considered as hazardous, due to their respective high concentration of nickel and aluminum contents. This article presents the study, done to avoid environmental ...
Ru‐Pt catalysts supported on Al2O3 and SiO2─Al2O3 for the selective ring opening of naphthenes
(Wiley, 2019-11)
Alumina and silica-alumina supported Ru-Pt catalysts were evaluated for the ring opening of naphthenes. Pt, Ru and Ru-Pt catalysts were prepared by impregnation of inorganic precursors over γ-alumina and silica-alumina ...
Stable and efficient metal-biochar supported catalyst: degradation of model pollutants through sulfate radical-based advanced oxidation processes
(Springer, 2020-07)
This study focuses on the synthesis of metal-based biochar catalysts and their catalytic activation of peroxymonosulfate (PMS, HSO5−) for the degradation of three diferent wastewater model pollutants employing advanced ...
Síntesis, Desarrollo y Optimización de un Catalizador para la Producción Verde de Biodiesel
(2011-11-18)
This work was conducted in two stages. The first stage was the selection of a catalyst out of seven catalysts considered environment friendly (ZnO, Al2O3, TiO2, ZrO2, V2O5, MoO3 and WO3), evaluating each in a test tube and ...
