A method is presented for the hydrothermal synthesis of binderless zeolite A bars and tubes with high purity from amorphous aluminosilicate extrudates. The solid that was separated from a hydrogel was mixed with an aqueous solution of hydroxyethyl cellulose to obtain a paste, which was extruded into bars and tubes. After calcination, amorphous bars and tubes were converted to zeolite A in the liquid phase that was separated from the hydrogel. The zeolite bars and tubes were composed of cubic zeolite A crystals and had only macropores with an average pore size of similar to 3 mu m besides the zeolite pores. Zeolite A bars exhibited moderate mechanical strength, with a crush strength of 0.4 MPa.

Synthesis of ZSM-5-type zeolite membranes on, porous disks loaded with different amounts of seed
Dincer, Eser; Kalıpçılar, Halil; Culfaz, Ali (American Chemical Society (ACS), 2008-07-16)
ZSM-5-type zeolite membranes were synthesized at 130 degrees C on alumina supports coated with seed crystals by vacuum seeding. Compact and uniform ZSM-5 layers were formed on the support surfaces when the amount of seed was less than 1 mg/cm(2). Higher loading of seed crystals resulted in an asymmetric structure with a compact and uniform ZSM-5 layer on top, the support at the bottom, and the seed layer in between. Fifty-one membranes were prepared on supports coated with different amounts of seed. About 7...
Pre-ozonation of aqueous azo dye (Acid Red-151) followed by activated sludge process
Gokcen, Fulya; Ozbelge, Tulay A. (Elsevier BV, 2006-10-15)
In this study, the efficiency of the integrated process was investigated in which the pre-ozonation step was followed by activated sludge process (ASP) in treating the aqueous Acid Red-151 (AR 151) solutions. The percent dye removal in the integrated process was found to be 47% for a pre-ozonation time of 30 min, instead of 25% in the singly ASP without pre-ozonation. The treatment efficiency of this process could be higher if the pre-ozonation time of 120 min yielding maximum enhancement of biodegradabilit...
Simultaneous production of tert-Amyl ethyl ether and tert-Amyl alcohol from isoamylene-ethanol-water mixtures in a batch-reactive distillation column
Varisli, D; Doğu, Timur (American Chemical Society (ACS), 2005-07-06)
tert-Amyl ethyl ether (TAEE) and tert-amyl alcohol (TAA), which are the attractive alternatives to methyl tert-butyl ether as octane-enhancing gasoline-blending components, are produced by the simultaneous etherification and hydration of 2-methyl-2-butene (2M2B) in a batch-reactive distillation column. It was shown that, by changing the reboiler temperature in the range of 90-124 degrees C, significant increases of the overall fractional conversion of 2M2B, reaching values of 0.99, were achieved in this sys...
Synthesis of alpha-Fe2O3/TiO2 heterogeneous composites by the sol-gel process and their photocatalytic activity
Bouziani, Asmae; PARK, JONGEE; Öztürk, Abdullah (Elsevier BV, 2020-09-01)
alpha-Fe2O3/TiO2 heterogeneous composites were synthesized by the sol-gel process to increase the photocatalytic activity of TiO2. The structural, morphological, and optical characteristics of the composites were determined by X-ray diffraction, scanning electron microscope, and UV-vis diffuse reflectance spectroscopy. Results revealed that the incorporation of alpha-Fe2O3 to TiO2 widened the visible light absorption ability of TiO2. It was realized that the calcination temperature plays a crucial role in m...
Development and application of novel bio-magnetic membrane capsules for the removal of the cationic dye malachite green in wastewater treatment
Ali, Imran; Peng, Changsheng; Naz, Iffat; Lin, Dichu; Saroj, Devendra P.; Ali, Mohsin (Royal Society of Chemistry (RSC), 2019-01-29)
Novel bio-magnetic membrane capsules (BMMCs) were prepared by a simple two-step titration-gel cross-linking method using a polyvinyl alcohol (PVA) and sodium alginate (SA) matrix to control the disintegration of phytogenic magnetic nanoparticles (PMNPs) in an aqueous environment, and their performance was investigated for adsorbing cationic malachite green (MG) dye from water. The prepared BMMCs were characterized by FTIR, powder XRD, SEM, EDX, XPS, VSM and TGA techniques. The findings revealed that the hys...
