The effect of extra framework species and acid properties of dealuminated zeolitic support on the catalytic behavior of palladium in n-hexane isomerization reaction

Autor: Hanene Najar, Abdelhamid Ghorbel, Mongia Saïd Zina

Publikováno v: Reaction Kinetics, Mechanisms and Catalysis. 111:775-790

Isomerization of n-hexane was carried out over palladium based catalysts prepared by aqueous ion exchange with dealuminated NaY-zeolite support. The dealumination was realized using acid solutions of HNO3, HCl and H2SiF6 with different concentrations

Catalytic activity of palladium supported on mesoporous modified Y-zeolite in methane combustion

Autor: Abdelhamid Ghorbel, Hanene Najar, M. Saïd Zina

Publikováno v: Kinetics and Catalysis. 51:602-608

Palladium-based catalysts were prepared by the ion-exchange method with dealuminated HY zeolite as support. The support dealumination was realised using acid solution of HNO3, HCl or H2SiF6. The high activity of prepared catalysts for methane combust

Catalytic conversion of N2O over palladium catalysts based on dealuminated faujasite

Autor: Mongia Saïd Zina, Hanene Najar, Abdelhamid Ghorbel, Gérard Delahay

Publikováno v: Progress in Reaction Kinetics and Mechanism
Progress in Reaction Kinetics and Mechanism, Science Reviews 2000 Ltd 2015, 40, pp.343-352. ⟨10.3184/146867815X14413752286100⟩

Dealumination of the faujasite support was realised using a hydrothermal treatment at different temperatures (625 – 700°C). Then palladium catalysts were prepared by an ion exchange method. The prepared catalysts exhibited a high and constant acti

Study of the effect of the acid dealumination on the physico-chemical properties of Y zeolite

Autor: Hanene Najar, Mongia Saïd Zina, Abdelhamid Ghorbel

Publikováno v: Reaction Kinetics, Mechanisms and Catalysis.

The aim of the present work was to combine different physicochemical techniques, namely X ray diffraction, IR spectroscopy, and multinuclear (29Si and 27Al) solid-state NMR spectroscopy, to study the aluminum distribution and to determine the silicon
