Catalizadores metálicos soportados para la obtención de gas de síntesis mediante reformado seco de metano
(2016-05-06)
Se estudiaron catalizadores de Ru e Ir soportados sobre gamma alúmina pura y modificada con metales alcalinos (Na y K) y alcalinotérreos (Ba, Ca y Mg) a fin de obtener materiales catalíticos con elevada actividad, selectividad ...
Design of catalyst systems for the one-pot synthesis of menthols from citral
(Academic Press Inc Elsevier Science, 2007-04)
Stable, active, and highly selective bifunctional Ni/Al-MCM-41 catalysts were developed for the one-pot synthesis of menthols from citral. The liquid-phase hydrogenation of citral to citronellal was studied on silica-supported ...
Monitoring the Activation of Copper-Containing Zeotype Catalysts Prepared by Direct Synthesis Using in Situ Synchrotron Infrared Microcrystal Spectroscopy and Complementary Techniques
(American Chemical Society, 2014-02)
The use of copper polyamine complexes as structure directing agents for microporous solids offers a direct route to the inclusion of Cu2+ complex cations in their pores: upon calcination, this gives active catalysts for ...
Phenol methylation on acid catalysts: Study of the catalyst deactivation kinetics and mechanism
(Elsevier Science, 2014-01)
The kinetics and mechanism of coke formation and catalyst deactivation during the synthesis of cresols from phenol methylation were investigated on SiO2–Al2O3, tungstophosphoric acid (HPA) supported on silica, and zeolites ...
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) ...
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 ...
V2O5/TiO2 catalyst xerogels: Method of preparation and characterization
(Kluwer Academic Publ, 2002-08-01)
This work describes a modified sol-gel method for the preparation of V2O5/TiO2 catalysts. The samples have been characterized by N-2 adsorption at 77 K, X-ray Diffractometry (XRD), Scanning Electronic Microscopy (SEM/EDX) ...
