Spatial Distribution of Mordenite in Crowley Lake Columns
, 2019 The Crowley Lake Columns formed after a rhyolitic explosion that occurred 760,000 years ago and produced the Bishop Tuff. These columns formed out of the Bishop Tuff hydrothermally which led to the precipitation of the mineral mordenite, (Na2,Ca,K2 ...

Boric Acid Post-Modified [Al]ZSM-5 Zeolites: Properties, Acidity, and Ethanol/Ethene Conversion. [PDF]
ChemistryThe modification of MFI zeolites with boric acid leads to the formation of framework boron, unstable surface species, and unbound deposits. Relevant BAS for catalysis and access to pores are strongly reduced. The boric acid is removed upon converting C1 or C2 alcohols and ethene. ABSTRACT The effect of boric acid post‐modification on [Al]ZSM‐5 zeolites

Mild modification method for the generation of mesoporosity in synthetic and natural mordenite
Bulletin of the Chemical Society of Ethiopia, 2015 Zeolites are widely used as acid catalysts for the synthesis of fine chemicals in industrial processes. However, in most cases, diffusion limitations in the microporous network of zeolites prevents a good catalytic performance.
