Selective aqueous-phase hydrogenation of glucose and xylose over ruthenium-based catalysts: Influence of the support
(Elsevier Science, 2020-11)
Sorbitol and xylitol are value-added renewable chemicals that can be obtained from biomass through the hydrogenation of monosaccharides (glucose and xylose, respectively) using ruthenium-based catalysts. This paper reports ...
Catalytic Steam Gasification of Glucose for Hydrogen Production Using Stable Based Ni on a γ–Alumina Fluidizable Catalyst
(De Gruyter, 2019)
Six different Ni-based fluidizable catalysts were synthesized using both incipient impregnation and co-
impregnation. Ni-based catalysts were also promoted with 2.0 wt% La or alternatively with 2 wt% Ce. The
preparation ...
High-Active Metallic-Activated Carbon Catalysts for Selective Hydrogenation
(Hindawi Limited, 2018-07)
A series of low-loaded metallic-activated carbon catalysts were evaluated during the selective hydrogenation of a medium-chain alkyne under mild conditions. The catalysts and support were characterized by ICP, hydrogen ...
Superficial properties of activated carbon fiber catalysts produced by green synthesis and their application in water purification
(Springer Heidelberg, 2020-07)
Catalysts of Pd-In supported on activated carbon fiber were synthesized, characterized, and evaluated for the removal of nitrogen oxyanions from water. The work was carried out aiming the development of a green synthesis ...
Biodiesel production through esterification applying ionic liquids as catalysts
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilDepartamento Acadêmico de Engenharia QuimicaEngenharia QuímicaUTFPR, 2018-06-05)
Biodiesel is a liquid fuel obtained from several renewable sources by transesterification reaction of triglycerides. Its development is related to a new tendency: the search for alternatives to petroleum-based energy ...
Alternative route for the synthesis of high surface-area eta-Al2O3/Nb2O5 catalyst from aluminum waste
(Elsevier Science Sa, 2016)
This paper describes an alternative route for the production of a high-surface-area eta-Al2O3/Nb2O5 catalyst synthesized from aluminum waste and niobium ammonium oxalate (NH4H2[NbO-(C2O4)(3)]center dot 3H(2)O). The effects ...
Behavior of catalytic pellets at high reaction rates. The effect of edges
(American Chemical Society, 2006-01)
The diffusion and reaction problem in catalytic pellets of any shape subject to diffusive transport limitations is undertaken in this contribution. Effective reaction rates in three-dimensional (3D) catalysts can be evaluated ...
Strontium zirconate heterogeneous catalyst for biodiesel production: Synthesis, characterization and catalytic activity evaluation
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Strontium zirconate oxide was synthesized by co-precipitation and the citrate route and was evaluated as a heterogeneous catalyst for biodiesel production. The catalyst samples were characterized by XRD, FTIR, and TG, and ...
