Síntesis de SAPO-34 y SAPO-18 con propiedades mejoradas para la transformación de olefinas a partir de metanol

Authors:Teresa Álvaro Muñoz, Carlos Márquez Álvarez, Enrique Sastre
Groups of research:Molecular Sieves
In this work we have used different structure directing agents (SDAs) in the synthesis of SAPO-34 trying to modify the location and nature of the acid centres and, so evaluate the influence of this parameter in the catalytic performance of the catalysts. In order to try to improve the accessibility of the reagent to the active centres of SAPO-34, we have also studied the influence of different mesoporogen agents –nanometric carbons or chitosan- with the objective of generating mesoporosity in the SAPO-34 materials and, in that way, inhibiting their deactivation. Catalyst SAPO-34 synthesized with TEAOH as SDA has demonstrated the best performance in the MTO reaction due to its smaller crystal size, higher surface area and higher acidity. The use of mesoporogen additives, under the experimental conditions studied, does not improve the catalytic performance of these materials.
