- PublicaciónITQ-69: A Germanium-Containing Zeolite and its Synthesis, Structure Determination, and Adsorption Properties(John Wiley & Sons, 2021-05-17) Sala-Gascon, Andres; Pérez-Botella, Eduardo; Jorda Moret, Jose Luis; Cantin Sanz, Angel; Rey Garcia, Fernando; Valencia Valencia, Susana; Instituto Universitario Mixto de Tecnología Química; Ministerio de Educación, Cultura y Deporte; Ministerio de Ciencia, Innovación y Universidades; MINISTERIO DE ECONOMÍA, INDUSTRIA Y COMPETITIVIDAD[EN] In this work, a new zeolite named as ITQ-69, has been synthesized, characterized and its application as selective adsorbent for industrially relevant light olefins/paraffins separations has been assessed. This material has been obtained as pure germania as well as silica-germania zeolites with different Si/Ge ratios using a diquaternary ammonium cation as organic structure directing agent. Its structure was determined by single-crystal X-Ray diffraction showing a triclinic unit cell forming a tridirectional small pore channel system (8x8x8R). Also, it has been found that Si preferentially occupies some special T sites of the structure as deduced from Rietveld analysis of the powder X-ray diffraction patterns. In addition, the new zeolite ITQ-69 has been found to be stable upon calcination and thus, its adsorption properties were evaluated, showing a promising kinetic selectivity for light olefin separations in the C3 fraction.
- PublicaciónUse of Alkylarsonium Directing Agents for the Synthesis and Study of Zeolites(John Wiley & Sons, 2019-12-18) Saez-Ferre, Sara; Lopes, Christian W.; Simancas-Coloma, Jorge; Vidal Moya, José Alejandro; Blasco Lanzuela, Teresa; Agostini, Giovanni; Mínguez Espallargas, Guillermo; Jorda Moret, Jose Luis; Rey Garcia, Fernando; Oña Burgos, Pascual; Instituto Universitario Mixto de Tecnología Química; Generalitat Valenciana; European Regional Development Fund; Ministerio de Educación y Ciencia; Ministerio de Economía y Competitividad; Ministerio de Ciencia, Innovación y Universidades; Coordenaçao de Aperfeiçoamento de Pessoal de Nível Superior, Brasil[EN] Expanding the previously known family of -onium (ammonium, phosphonium, and sulfonium) organic structure-directing agents (OSDAs) for the synthesis of zeolite MFI, a new member, the arsonium cation, is used for the first time. The new group of tetraalkylarsonium cations has allowed the synthesis of the zeolite ZSM-5 with several different chemical compositions, opening a route for the synthesis of zeolites with a new series of OSDA. Moreover, the use of As replacing N in the OSDA allows the introduction of probe atoms that facilitate the study of these molecules by powder X-ray diffraction (PXRD), solid-state nuclear magnetic resonance (MAS NMR), and X-ray absorption spectroscopy (XAS). Finally, the influence of trivalent elements such as B, Al, or Ga isomorphically replacing Si atoms in the framework structure and its interaction with the As species has been studied. The suitability of the tetraalkylarsonium cation for carrying out the crystallization of zeolites is demonstrated along with the benefit of the presence of As atoms in the occluded OSDA, which allows its advanced characterization as well as the study of its evolution during OSDA removal by thermal treatments.

The new microporous structure, ITQ-50, has a unique structure and improved performance for propene/propane separation with respect the parent material ITQ-29.
