In this work, ceramic monoliths were coated with powders based on exchanged Cs and/or Co cations in Na-mordenite (MOR) zeolite. SEM images showed that zeolite particles fill the macropores of cordierite walls and form a continuous layer approximately 40 µm good adherence. XPS analysis revealed are present film surface solely as Co2+ Cs+ at exchange positions The monolithic structures evaluated ...

Nanocrystalline mordenite (MOR) zeolites were hydrothermally synthesized in a single step with commercial cetyltrimethylammonium (CTA) hydroxide as the sole organic template, while aluminum source was varied typical synthesis gel. CTA can effectively reduce crystal growth of MOR zeolites, some cases selectively - and b -directions unit cell . These nanocrystalline do not only have larger extern...

Zeolites with their unique properties find applications in various fields, including medicine, agronomy, ecology, production of detergents and drying agents, a number industrial processes. Among zeolites, mordenite is particularly widespread because its high silica/alumina ratio, which allows it to resist exposure temperatures acidic gases liquids. Mordenite commercially available as natural mi...

In this work, the interactions of methyl tert-butyl ether (MTBE) on different dealuminated high silica zeolites were studied by means of both experimental and computational approaches. Zeolites with different textural and surface features were selected as adsorbents and the effect of their physico-chemical properties (i.e. pore size architecture and type and amount of surface OH sites) on sorpt...

eethylene polymerization catalysts became available in an enormous variety. the challenge in this research is to find catalysts that are able to connect ethylene molecules in such a way that not only linear chains are produced but variations like branched materials that possess very interesting mechanical properties like linear low density polyethylene (lldpe). in this contribution, three diffe...

Spatial restrictions around catalytic sites, provided by molecular-sized micropores, are beneficial to reaction selectivity but also inherently limit diffusion. The molecular transport can be enhanced by introducing meso- and macropores. However, the impact of this extraframework porosity on the local nanoscale reactivity is relatively unexplored. Herein we show that the area of enhanced reacti...

Zeolites have been successfully applied as catalysts in the pyrolysis of plastics to obtain valuable lower molecular weight hydrocarbon compounds. In present work, mordenite was directly synthesized and chemically modified from commercial increase pore volume. For first time, performance these mordenites compared with that an alkali-treated ZSM-5 for assisting simulated urban plastic waste. The...
