dc.description.abstract | Nano-SAPO-34 zeolite catalyst (20 nm crystal size) has been stabilized by hydrothermal treatment. After steamed at high temperatures (T >= 550 degrees C), its textural properties and high lifetime during the reaction of methanol to olefins (MTO) are preserved, despite the decrease in acidity, even after months of contact with moisture. The stabilization effect is attributed to the migration of silicon to larger silicon islands in which the contribution of silicon on the edge is lower after steaming. Stabilization is not successful by a thermal treatment in air in the absence of water. Steaming at temperature >400 degrees C is required for achieving hydrothermal stabilization. A stability test for SAPO-34 in MTO reaction is proposed. (C) 2015 Elsevier Inc. All rights reserved. | es_ES |
