Solid catalysts obtained from wastes for FAME production using mixtures of refined palm oil and waste cooking oils
More than 95% of biodiesel production feedstocks come from edible oils, however it may cause some
problems such as the competition of land use between food production and biodiesel production. The
waste cooking oils (WCO) ...

Bifunctional mesoporous silica nanoparticles as cooperative catalysts for the Tsuji-Trost reaction: tuning the reactivity of silica nanoparticles
(Royal Society Chemistry - RSCCambridge, 2013-01)
Bifunctional mesoporous silica nanoparticles (MSNs) bearing Pd-complexes and additional basic siteswere prepared and tested as cooperative active catalysts in the Tsuji–Trost allylation of ethyl acetoacetate. Functionalization ...
Isomerização do n-Hexano por platina suportada na zeólita H-ZSM-5 : efeito do teor de alumínio
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2011-08-01)
The objective of this study was to verify the influence of the Si/Al ratio (11.5, 15.0, 25.0, 40.0 and 140.0) in zeolite ZSM-5 in the conversion, activity, selectivity and stability as bifunctional catalysts (Pt/H-ZSM-5) ...
Hydrothermal synthesis of Mo-V mixed oxides possessing several crystalline phases and their performance in the catalytic oxydehydration of glycerol to acrylic acid
(2017-01-01)
The one-step oxydehydration of glycerol to acrylic acid over molybdenum and vanadium mixed oxides was investigated. The Mo-V oxide catalysts were prepared by a simple hydrothermal method under different synthesis and ...
Influence of the support on the selective ring opening of methylcyclohexane and decalin catalyzed by Rh–Pd catalysts
(Elsevier, 2014-12)
Rh–Pd catalysts supported on Al2O3, SiO2 and SiO2–Al2O3 (SIRAL 40) were studied for methylcyclohexane (MCH) and decalin ring opening reactions. It was found that the Rh/Pd atomic ratios were similar to the theoretically ...

Bifunctional thiosquaramide catalyzed asymmetric reduction of dihydro-β-carbolines and enantioselective synthesis of (-)-coerulescine and (-)-horsfiline by oxidative rearrangement
(Royal Society of Chemistry, 2020-10-21)
Tetrahydro-β-carboline (THBC) is a tricyclic ring system that can be found in a large number of bioactive alkaloids. Herein, we report a simple and efficient method for the synthesis of enantiopure THBCs through a chiral ...
