Zeolites 5A were obtained by ion exchange of a zeolite 4A, previously synthesized the hydrothermal method from precursor kaolin, with aim removal As(V) drinking water and Pb(II) irrigation surface water. Zeolite was characterized before after adsorption X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, photoelectron spectroscopy. To find mechanisms both As Pb in r...

The plasma-catalytic oxidation of soot was studied over zeolite-supported vanadium catalysts, while four types zeolites (MCM-41, mordenite, USY and 5A) were used as catalyst supports. rate followed the order V/MCM-41 > V/mordenite V/USY V/5A, 100% achieved at 54th min reaction V/mordenite. CO2 selectivity process follows opposite V/M catalyst. A wide range characterizations including N2 adso...

Abstract Biomass gasification is a thermochemical conversion process of solid biomass into gaseous fuel called producer gas that can be used to generate power and electricity. The consists around 47% Nitrogen (N 2 ), 24% Carbon Monoxide (CO), 16% Dioxide (CO 12% Hydrogen (H 1% Methane (CH 4 ). However, ) content in the reduces its heating values as N acts diluent because low calorific value (LC...

Herein, we report a three-dimensional porous TiO2/Fe2TiO5/Fe2O3 (TFF) inverse opal through in situ thermal solid reactions for photoelectrochemical water splitting. The Fe2TiO5 interfacial layer within TFF acting as bridge to tightly connect TiO2 and Fe2O3 reduces the charge transfer resistance, suppresses bulk carrier recombination. optimized displays remarkable photocurrent density of 0.54 mA...

The aim of our work is to study phase composition, particle size and magnetic response of Fe2O3/TiO2 nanocomposites with respect to the final annealing temperature. Those nanomaterials are considered as smart catalysts, separable from a liquid/gaseous phase by applied magnetic field. The starting product was obtained by an ecologically acceptable route, based on heterogeneous precipitation of t...

In this study pre-combustion capture of carbon dioxide from hydrogen was performed using a 5A zeolite adsorber. A one column thermal pressure swing adsorption (TPSA) process was studied in the bulk separation of a CO2/H2 mixture (50:50 vol%). The adsorption dynamics of the zeolite bed were investigated by breakthrough experiments to select the suitable range for operational factors in the desig...
