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...

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...
