A simple an efficient approach to confine Cu/ZnO methanol synthesis catalysts in the ordered mesoporous SBA-15 silica

García Trenco, Andrés; Martinez Feliu, Agustin (Elsevier, 2013-10-15)

The ammonia-driving deposition-precipitation (ADP) method has been applied with the purpose of confining active Cu/ZnO methanol synthesis phases inside the pores of the ordered mesoporous SBA-15 silica. Thus, a series of ...
Desarrollo de catalizadores híbridos CuZnOAl2O3/zeolita para el proceso de síntesis directa de DME

García Trenco, Andrés (Universitat Politècnica de València, 2014-01-07)

El plan de investigación se centra en el estudio y diseño de catalizadores híbridos para el proceso de síntesis directa de dimetil éter (DME) a partir de gas de síntesis, también conocido en la literatura como "Syngas-To-DME ...
Direct synthesis of DME from syngas on hybrid CuZnAl/ZSM-5 catalysts: New insights into the role of zeolite acidity

García Trenco, Andrés; Martinez Feliu, Agustin (Elsevier, 2012)

[EN] A commercial HZSM-5 zeolite (Si/Al = 16) was submitted to mild acid treatment and partial exchange of H+ by Na+ and Co2+ cations in order to produce samples with different amounts and strengths of Brensted and Lewis ...
Estudio de la acidez en catalizadores bifuncionales para la síntesis directa de DME

García Trenco, Andrés (Universitat Politècnica de València, 2012-01-25)

Catalizadores bifuncionales basados en Cu/Zn/Al203 y la zeolita HZSM-5 fueron evaluados en el proceso de síntesis directa de DME a partir de gas de síntesis (STD) con el fin de determinar la influencia del número, fortaleza ...
Study of the interaction between components in hybrid CuZnAl/HZSM-5 catalysts and its impact in the syngas-to-DME reaction

García Trenco, Andrés; Vidal Moya, José Alejandro; Martinez Feliu, Agustin (Elsevier, 2012-01-05)

[EN] Hybrid CuZnAl(CZA)/HZSM-5 catalysts were prepared by three mixing methods in order to analyze the possible existence of interactions between components and their impact in the STD process, namely: (a) grinding of ...
The impact of zeolite pore structure on the catalytic behavior of CuZnAl/zeolite hybrid catalysts for the direct DME synthesis

García Trenco, Andrés; Valencia Valencia, Susana; Martinez Feliu, Agustin (Elsevier, 2013)

[EN] In this work, the influence of the pore structure of 10-ring zeolites used as the methanol dehydration func-tion in CuZnAl(CZA)/zeolite hybrid catalysts was studied for the direct dimethyl ether (DME) synthesis. Tothis ...
The influence of zeolite surface-aluminum species on the deactivationof CuZnAl/zeolite hybrid catalysts for the direct DME synthesis

García Trenco, Andrés; Martinez Feliu, Agustin (Elsevier, 2014-05-15)

[EN] The influence of the nature and amount of zeolite-surface Al species on the deactivation behavior ofbifunctional CZA/zeolite hybrid catalysts during the direct DME synthesis (260◦C, 4.0 MPa) from syn-gas (66% ...
