The present work introduces the study of the CO2 capture process by zeolites synthesized from paper sludge and scrap glass. Zeolites ZSM-5, analcime and wairakite were produced by means of two types of Structure Directing Agents (SDA): tetrapropilamonium (TPA) and ethanol. On the one hand, zeolite ZSM-5 was synthesized using TPA; on the other hand, analcime and wairakite were produced with etha...

─The Nafion/zeolite composite membranes were synthesized for polymer electrolyte fuel cells (PEMFCs) by adding zeolite in the matrix of Nafion polymer. Two kinds of zeolites, Analcime and Faujasite, were used. The physicochemical properties of the composite membranes such as water uptake, ion-exchange capacity, hydrogen permeability, and proton conductivity were determined. The fabricated compo...

Production of a high value zeolite from fly ash has been shown to be an avenue for the utilization of South African fly ash which presently constitutes a huge disposal problem. The synthesis of zeolites Na-P1 and analcime on a micro-scale has been successful and preliminary investigation shows that scale-up synthesis is promising. However, the post-synthesis supernatant waste generated contains...

To investigate template effect on physicochemical properties of zeolite and enhance the molecular sieving properties, adsorption of methionine amino acid was studied by spectroscopic methods. Four zeolites such as methionine templated analcime, methionine templated zeolite P, N, N-dibenzyl N,N,N,N-tetramethylethylenediamine (DBTMED) templated analcime and free template analcime were synthesized...

A Novel modified Analcime (Na16 (Al16Si32O96) •16H2O) zeolite with a new molar ratio have been successfully synthesized. In order to investigate the role of the template, Different samples were synthesized with and without Tetramethylammoniumhydroxide (TMAOH) template through hydrothermal method. Different synthesis times (24, 36 and 72 hours) and molar ratios have been utilized. The optimum sa...

a type of zeolite from the analcime family was prepared by using triethanolamine, silica gel and sodium aluminate. the average particle size was around 24 µm. ftir, xrd and sem results approved the type of zeolite which was formed

In this study, chemical and structural properties of natural analcime-rich zeolite tuff from Turkey that ion-exchanged forms investigated. The microporous structure the presence extra-framework cations are great importance for characterizing unique zeolites. Ion-exchanged (K+, H+ Ca2+) analcime were prepared with 1 M KNO3,1 Ca(NO3)2 HCl solutions in a shaker 6 hours at 80 °C. obtained samples c...

The aim of this study was to examine the removal ammonium ions from a synthetic model solution by using Na-zeolite-based geopolymers. Na-zeolite (=analcime) is residue mining industry. Three adsorbents were prepared different production steps and metakaolin as blending agent. These novel investigated in fixed-bed column system where effects flow rates with initial concentration 40 mg/L studied....

the capacity of natural zeolites to absorb anionic pollutants from water is limited. this limitation can be overcome by modifying the surface of the minerals with organic cations. in this research, natural zeolite, analcime was used for removing the nitrate and nitrite impurities from aqueous solutions. the surface of the zeolite was modified by tetramethylammonium and tetraethylammonium ions t...
