A study of the particle size effect on the pozzolanic activity of an equilibrium catalyst
(2011)
A study by thermogravimetry was done to evaluate the influence of the particle size on the pozzolanic activity of a residual equilibrium catalyst from a fluid catalytic cracking unit of a Brazilian refinery. For this ...
Liquid-phase transfer hydrogenation of furfural to furfuryl alcohol on Cu–Mg–Al catalysts
(Elsevier, 2014-08)
The liquid-phase transfer hydrogenation of furfural on Cu-based catalysts was studied. Catalysts were prepared by incipient wetness impregnation (Cu/SiO2) and co-precipitation (Cu–Mg–Al). The effect of metal-support ...
Immobilized Rh, Ru, Pd and Ni complexes as catalysts in the hydrogenation of cyclohexene
(Elsevier Science, 2004-10)
Complexes of Rh, Ru, Pd and Ni with tridecylamine and chloride as ligands were prepared and tested as heterogeneous catalysts for the hydrogenation of cyclohexene. The Wilkinson's complex was used as a reference catalyst. ...
Liquid-phase transfer hydrogenation of furfural to furfuryl alcohol on Cu-Mg-Al catalysts
(Elsevier, 2015-01)
The liquid-phase transfer hydrogenation of furfural on Cu-based catalysts was studied. Catalysts were prepared by incipient wetness impregnation (Cu/SiO2) and co-precipitation (Cu-Mg-Al). The effect of metal-support ...
An environmental friendly catalyst for the high temperature shift reaction
(Studies in Surface Science and Catalysis, 2000)
The need for environmental protection has demanded the searching nontoxic
catalysts easily handled and discarded. This work deals with the use of
aluminum as a substitute of chromium, in iron- and copper-based catalysts
for ...
Effect of the relationship between particle size, inter-particle distance, and metal loading of carbon supported fuel cell catalysts on their catalytic activity
(SPRINGERDORDRECHT, 2012)
The effect of the relationship between particle size (d), inter-particle distance (x(i)), and metal loading (y) of carbon supported fuel cell Pt or PtRu catalysts on their catalytic activity, based on the optimum d (2.5-3 ...
Ru-Promoted Ni/γAl2O3 Fluidized Catalyst for Biomass Gasification
(MDPI, 2020-03-10)
Fluidizable catalysts based on Ni/γAl2O3 with added Ru were used for the gasification of
a lignin surrogate (2-methoxy-4-methylphenol) in a fluidized CREC Riser Simulator reactor. This was
done in order to quantify lignin ...
Glycerol-enriched heterogeneous catalyst for biodiesel production from soybean oil and waste frying oil
(Elsevier, 2015-01)
In the present work, biodiesel production using a glycerol enriched heterogeneous catalyst was studied. For that purpose, the catalyst performance at different glycerol concentrations and reaction conditions (under ambient ...
Influence of Na content on the catalytic properties of Pt-Ir/Al2O3 catalysts for selective ring opening of decalin
(Elsevier, 2014-04)
The influence of the Na addition on Pt-Ir/Al2O3 on the reaction of selective ring opening of decalin and methyl cyclopentane was studied. The catalysts were evaluated by means of TPR, pyridine TPD, TEM, FTIR-CO and by the ...
Copper mesoporous materials as highly efficient recyclable catalysts for the reduction of 4-nitrophenol in aqueous media
(Pergamon-Elsevier Science Ltd, 2018-08-09)
Two mesoporous-based catalysts with different nominal copper loads (10 and 24% w/w) were prepared from impregnation of the MCM-41 support with copper acetylacetonate: Cu/MCM-41-10 and Cu/MCM-41-24, respectively. Samples ...
