Predicting crystal growth via a unified kinetic three-dimensional partition model
A general simulation approach that can replicate, and in theory predict, the growth of a wide range of crystal types, including porous, molecular and ionic crystals, is demonstrated....
Characterization and studies of Si and Brønsted site developments in SAPO-18 and SAPO-34 during and after hydrothermal treatments
Characterization of catalytic sites in microporous materials using solid-state NMR. An ex-situ and in-situ high temperature flow study.
Structural changes in the methanol-to-olefin (MTO) catalyst SAPO-34 after/during hydrothermal treatment
Structural changes in SAPO-34 due to hydrothermal treatment. A NMR, XRD, and DRIFTS study
When SAPO-34 is used as an industrial MTO catalyst, structural transformations leading to permanent deactivation are inevitable. The performance loss is linked principally to a redistribution of Si in the material, leading to the formation of Si-islands/aggregates with a concomitant loss of Brønsted...
Highly stable and selective propane dehydrogenation catalyst
In-Situ Atomic Force Microscopy Study of the Dissolution of Nanoporous SAPO-34 and SAPO-18
In-situ atomic force microscopy has been used to investigate the dissolution behavior of industrially relevant silicoaluminophosphate catalysts SAPO-34 and SAPO-18. Spiral growth is prevalent on these materials and it is common for the spirals to be composites of multiple dislocation sources. The sp...
Studies of SAPO-34 during and after hydrothermal treatment
CHA/AEI intergrowth materials as catalysts for the Methanol-to-Olefins process
A series of SAPO-34/SAPO-18 intergrowth materials were prepared with a range of silicon content from 0.5 to 7.0%, where low levels of silicon resulted in SAPO-18 and higher levels resulted in CHA/AEI intergrowths. These materials were tested for their performance in the Methanol-to-Olefins reaction....
