Obtención de hidrocarburos de interés industrial a partir del reciclado químico de residuos plásticos utilizando zeolitas microporosas pentasilíceas
(2011)
El aumento en los niveles de consumo de plásticos en la sociedad moderna, ha traído consigo
un enorme incremento en la generación de residuos. Por ello, en este trabajo, se plantea
adoptar como alternativa de tratamiento ...
Inhibition of the hydrogenation of tetralin by nitrogen and sulfur compounds over Ir/SBA-16
(2011)
In this work we study the catalytic properties of 5 wt.% Ir-containing SBA-16 catalysts (with and without aluminum as heteroatom), in the hydrogenation of tetralin to decalin, in the presence of 100 ppm of N as quinoline, ...
XANES-PCA analysis of Ti-species in MCM-41 mesoporous silica synthesized by different methods
(2011)
MCM-41 mesoporous silica was prepared with Ti incorporated in the structure by two different ways: hydrothermal and atmospheric pressure by sol–gel method. To evaluate each synthesis, these materials were in situ investigated ...
Simultaneous optimization of methane conversion and aromatic yields by catalytic activation with ethane over Zn-ZSM-11 zeolite: the influence of the Zn-loading factor
(2011)
Experiment design-response surface methodology (RSM) is used in this work to model and optimize two responses in the process of activation of methane (C1) using ethane (C2) as co-reactant into higher hydro- carbons, over ...
Synthesis and characterization of new composites: PANI/Na-AlSBA-3 and PANI/Na-AlSBA-16
(2011)
The new aluminosilicate materials (Na-AlSBA-3 and Na-AlSBA-16) were synthesized for application in the preparation of composites. Silica mesoporous materials were obtained following the sol–gel method and post-synthesis ...
