“…The companies that are interested in providing an adequate destination for the parings pay to dispose this residue in landfills. In Brazil, the cost for that disposal is around R$ 70,00 per ton of non-hazardous residue; in European countries, this cost can reach R$ 340,00 (2010) [1] . The amount of labels and stickers discarded is huge, for they are largely used.…”

“…The concern about sustainable development lead to the necessity of the realization of researches on the use of sugarcane bagasse ashes; some researchers have already reported its use in Portland cements [5] and at the synthesis of porous materials [1] , such as microporous zeolites. Commercially, a small amount of ashes is reused at the civil construction industry, as well as fertilizer.…”

“…Zeolites can be successfully obtained from different natural raw materials [1][2][3][4]. Moreover, various manufacturing and agro wastes have been studied as a starting material in synthesizing zeolite [5][6][7][8]. The chemical composition of the raw material used, particularly the presence of silicon and aluminum oxides, is one of the important factors responsible for obtaining various types of zeolites [9].…”

Currently, there has been a growing interest of zeolite materials for industrial and scientific purpose. Synthetic zeolites are more often used than natural ones due to its higher purity and more uniform particle sizes. Numerous investigations are conducted in searching of inexpensive raw materials suitable for zeolite synthesis. Moreover, the temperature, pressure, times and SiO 2 /Al 2 O 3 ratio are the most important parameters which play key roles in the synthesis processes. Due to such a large number of factors that affect the process, zeolite synthesis has been undergoing constant development. Nowadays, researchers focus on the methods of synthesizing zeolites at ambient temperature and pressure. Metakaolin and tuff are natural raw materials which can be turned into a brand new class of synthetic zeolites. However, each requires different method of synthesis in order to obtain a material with best physical properties. This paper discusses the process of alkaline activation of synthetic zeolites from natural raw materials: volcanic tuff excavated in Filipowice and metakaolin obtained from Rominco company. Two methods: fusion and low-temperature synthesis, were used in the presented research. Moreover, the physical properties of raw materials and zeolites obtained were shown. Based on the XRD analysis, it was verified that materials after the synthesis process contained zeolites A, Na-X and faujasite-Na. Furthermore, the dehydration and thermal decomposition phenomena of the tuff and metakaolin before and after the synthesis process were determined by coupled TG/MS techniques.

“…The disposal of large amounts of SCBA (sugarcane bagasse ash) has become a serious environmental problem. Therefore, this solid waste can be used to prepare zeolite [14]. On the other hand, CNTs (carbon nanotubes), due to their distinctive chemical and physical properties can be applied in gas separation process.…”

Abstract:The zeolite synthesis using waste as silicon source is a promising low-cost process. Sugarcane bagasse ash is a hazardous solid waste generated in large amounts in the sugar industry. Thus, development of new procedures for its productive reuse is relevant. Therefore, this waste was used to prepare a new ZCNT (zeolite/carbon nanotube material). In this work, ZCNT was applied in a CO 2 /CH 4 separation. The adsorption took place at 303 K under pressure of 0.1 until 20 bar and the data were fitted by Langmuir, Toth and Freundlich equations. The adsorbed amount at 20 bar found was 4.7 mmol of CO 2 /g and 4.1 mmol of CH 4 /g; at 3 bar the adsorbed amount was 4.1 mmol of CO 2 /g and 1.2 mmol of CH 4 /g. This result indicates that ZCNT has potential application in CO 2 /CH 4 separation at low pressures.
