Selective aqueous-phase hydrogenation of D-fructose into D-mannitol using a highly efficient and reusable Cu-Ni/SiO2 catalyst
(Pergamon-Elsevier Science Ltd, 2019-10)
D-fructose hydrogenation in aqueous phase, at 373 K and 40 bar, was performed using monometallic and bimetallic Cu-Ni/SiO2 catalysts prepared by precipitation-deposition at controlled pH, without any type of co-catalysts ...
Partial oxidation of methane over lanthana-supported catalysts derived from perovskites
(Elsevier, 2020-03-15)
Partial oxidation of methane is the most attractive route to produce syngas, since it produces H2/CO (molar) = 2, suitable for Fischer-Tropsch and methanol synthesis, besides the low energy consumption and low tendency to ...
Desenvolvimento de catalisadores para reforma e oxidação combinadas do metano
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2009-03-20)
In this work, we studied the effects of the promoters of support (ZrO2, La2O3, CeO2, CeO2-ZrO2, CeO2-ZrO2-La2O3 and La2O3) in the nickel catalysts supported on γ-Al2O3 were studied. The supports were prepared by wet ...
Isobutane Alkylation with Solid Catalysts based on Beta-Zeolite
(Elsevier Science, 2010-11)
The isobutane alkylation with butenes is a reaction in which the substitution of mineral acids, such as sulphuric and hydrofluoric acids, by solid acid catalysts is highly desirable. Solid catalysts with good activity and ...
Chemisorption of H2S on Copper-ETS-2: Experiment and Modeling of a Packed Column
(American Scientific Publishers, 2018-01)
Copper supported on Engelhard Titanosilicate-2 (ETS-2) showed to be a promising adsorbent for deep H2S removal (to sub-ppm levels) for gas purification applications at room temperature. Because of the high external surface ...
Catalytic and photocatalytic ozonation of phenol on MnO2 supported catalysts
(Elsevier Science B.V., 2007)
Effect of steaming treatment in the structure and reactivity of FCC catalysts
(John Wiley & Sons Inc, 2006-02)
The shape selectivity properties of USY zeolite crystallites is discussed, and is based on catalyst characterization, molecular simulation, catalytic experiments of model compounds and kinetic modeling. Typical FCC catalysts ...
Revisão crítica de técnicas para estudo de propriedades ácido-base de catalisadores heterogêneos
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia Química - EQ, 2022-09-12)
Currently, around 85% to 90% of all petrochemical and chemical industrial processes in large industries are catalytic. The insertion of catalytic steps makes the process more environmentally sustainable, as it leads to the ...
Sulfonic functionalized SBA-15 catalysts in the gas phase glycerol dehydration. Thermal stability and catalyst deactivation
(Elsevier Science, 2016-08)
The catalytic conversion of glycerol to acrolein was studied using sulfonic functionalized mesoporous silica SBA-15. The catalysts were prepared by the co-condensation method, conducting the silica synthesis and functionalization ...
