Mark W. Ackley, Salil U. Rege, Himanshu Saxena Praxair, Inc., 175 East Park Drive, Tonawanda, NY 14151, USA Received 22 July 2002; received in revised form 21 October 2002; accepted 22 October 2002 Abstract There are many natural zeolites of which a small number including clinoptilolite, chabazite, mordenite, erionite, ferrierite and phillipsite offer the greatest promise for gas separation. Patents and other literature have been surveyed to identify the bulk separation and purification processes for which these zeolites have potential. The abundance and low raw material cost of natural zeolites have rarely offset such disadvantages as variable composition, low purity ... Read more

Featuring Nikos Lygeros, a multi-talented researcher, a scientific collaborator with universities, a specialist adviser even to prime ministers and presidents, with expertise ranging from the use of zeolite in agriculture to contemporary geopolitical manoeuvres, we had the opportunity to speak for a short while on Thursday morning (4 August), in the welcoming surroundings of the Peripou multi-purpose venue. As the conversation progressed, we realised it could have gone on for hours, so we limited ourselves to topics such as hydrocarbons, geopolitics and Turkey. Mr Lygeros and his colleagues were in Agios Nikolaos to brief a group of producers on the ... Read more

Opinion on the approval of the environmental conditions set out in the Environmental Impact Assessment for the operation of a zeolite quarry covering an area of 83,427.30 square metres at the site ‘Kokkalo’ in the Community of Petrota, Municipality of Orestiada, Regional Unit of Evros, by ‘OLYMPOS S.A. INDUSTRIAL MINERALS’

The struggle for Greek zeolite is comparable to the struggle for the Greek Exclusive Economic Zone (EEZ) because it is a matter of national importance. We must therefore set aside local disputes and realise that the battle is not solely a matter for the courts. The crux of the matter lies elsewhere. Greek zeolite is one of our strategic reserves for the economy, just as the hydrocarbons and methane hydrates in the Greek EEZ are. zeolite, however, is more easily accessible, as it consists of surface deposits located on dry land. There are therefore no cross-border difficulties regarding its extraction ... Read more

Interview with N. Lygeros on Radio Elpida 96.1FM regarding the geostrategic position of Thrace, Greek zeolite and the utilisation of natural gas, on 22 April 2016.

No matter how hard they try to convince us, pessimistic approaches remain just that and do absolutely nothing to change the situation. Because it is only through large-scale projects that Greece can change and secure a future. Among these projects we include the Greek Exclusive Economic Zone (EEZ) with the EuroAsia Interconnector power cable, the EastMed natural gas pipeline, Greek zeolite with all its applications, and Greek innovation on the international stage. For these are not merely on a par with the Egnatia Motorway or the Ionian Motorway, or even the Rio–Antirrio Bridge, but they far exceed them, because they ... Read more

When we look at the problems we face, over time we come to realise that they stem not from their very nature, but from the way they are managed. So whilst we may have the impression that things are difficult, at least at first, after so many attempts we see that it is ultimately our own incompetence that traps us. We are, then, free yet besieged in our own homeland, but not by foreigners, merely by those we chose to solve our problems, without realising that this does not, in essence, concern them. For it is inconceivable that, after all ... Read more

Article Synopsis The International Symposium on Zeolite and Microporous Crystals 2015 (ZMPC2015) was held at the Sapporo Convention Center, Japan, from 28th June to 2nd July 2015 and had 435 attendees from 32 countries, with 75% from Japan, China, Korea or Taiwan. 396 presentations covered all aspects of zeolites and microporous crystals over four days. Catalysis and synthesis were the two main themes (46% of all presentations) with the others being: new porous materials; membranes and films; adsorption and diffusion; characterisation; novel applications; industrial applications; layered materials; computational chemistry; post-synthetic treatment; crystallography; and ion exchange. There were six plenary talks ... Read more

Takahiko Moteki and Raul F. Lobo Chem. Mater., Just Accepted Manuscript DOI: 10.1021/acs.chemmater.5b04439 Publication Date (Web): December 17, 2015 Copyright © 2015 American Chemical Society Abstract The fluoride method of zeolite synthesis yields materials with unique characteristics such as high Si/Al ratio, large crystal size, and hydrophobic properties, and it has been advantageous for the synthesis of new pure-silica or high-silica zeolites. It is often difficult, however, to incorporate aluminum—and thus bring about useful catalytic properties—in materials prepared through the fluorite method. In this report we show that FAU-type zeolites are an effective source of aluminum to the growing crystals ... Read more

DOI:10.1080/01496395.2015.1068332 Mahdeyeh Sheikhshoaieab, Tayebeh Shamspura, S. Zia Mohammadib Vahid Abstract A multi-element preconcentration–separation technique for metal ions is established. The procedure is based on complex formation of metal ions with Bis(2-hydroxy-1-naphtaldimine)-N-diethylentriamine (BHNDT) on nanoporous Analcime as sorbent followed by their determination using flame atomic absorption spectrometry. The effects of analytical parameters like pH, flow rates, eluent types and sorption capacity on the recoveries of metal ions are investigated. In order to predict the extraction ability of BHNDT for different metallic ions, DFT method is used to compute the binding energies of the cations to the title Schiff base compound. The ...

The Greek EEZ and Greek zeolite are highly strategic tools and constructive solutions that can provide practical help to our country. Consequently, these are issues that we must promote under all circumstances, come what may, because they are not merely cost-saving measures, but measures for recovery and growth. With the EEZ and zeolite, we are also operating in the maritime context of the Ionian Sea, the Peloponnese and Crete, and on land in Macedonia and Thrace… Read the rest here: Lygeros.org
