Optimization of ammonium fluoride route to hierarchical ZSM-5 zeolites

T. Onfroy, Z. Qin, S. Casale, V. Valtchev

Preparation of hierarchical zeolites via a chemical etching is a hot topic as it strongly improves microporous material's diffusive properties and thus their catalytic activity. However, an issue that is often neglected is the softening the post-treatment condition. Herein we we report the…

Enhanced activity of NiZrBEA catalyst for upgrading of biomass pyrolysis vapors to H2-rich gas

Jacek Grams, Robert Ryczkowski, Renata Sadek, Karolina Chałupka-Śpiewak, Sandra Casale, Stanislaw Dzwigaj

The main objective of these studies was development of competitive catalyst for the upgrading of biomass pyrolysis vapors to H2-rich gas. The performed experiments were devoted to determination of the effect of incorporation of zirconium into the structure of BEA zeolite on the performance of NiBEA…

Effects of dealumination on the performance of Ni-containing BEA catalysts in bioethanol steam reforming

Wojciech Gac, Magdalena Greluk, Grzegorz Słowik, Yannick Millot, Laetitia Valentin, Stanislaw Dzwigaj

The effects of dealumination of BEA zeolite on the formation of nickel active sites and the performance of Ni-containing BEA zeolite catalysts in the steam reforming of ethanol have been studied. Ni-containing BEA zeolite catalysts were prepared by the impregnation of unmodified and dealuminated…
