“…Their structure is built up with a framework of tetrahedral molecules, linked with shared oxygen atoms (Merrikhpour and Jalali 2013). Their crystal structure contains numerous channels and chambers of different sizes (in the order of several angstroms) giving them a range of unique ion-exchange, sorption, molecular-sieve, and catalytic properties (Derkowski et al 2006(Derkowski et al , 2007. Due to their unique properties, zeolites have found application in many branches of industry: in agriculture (e.g.…”

This paper presents a sub-pilot scale process of synthesis of Na-P1 zeolite from the coal fly ash. After establishing the appropriate synthesis conditions (20 kg of fly ash, 12 kg of NaOH, 90 dm 3 of water, the reaction temperature: 80°C and reaction time: 36 h), the highpurity (81 wt%) Na-P1 zeolite product was obtained. Its chemical, mineralogical, and textural properties were determined (by means of XRD, XRF, SEM-EDS and ASAP 2020). The synthesized material has a specific BET surface area (88 m 2 /g) c.a. six times higher than the fly ash from which it has been derived (15 m 2 /g). The pore-size distribution indicates a mesoporous character of the obtained zeolite, with the following pores size contents: micropores (2.76 %), mesopores (61.81 %), and macropores (35.43 %). The presented technological/production line is fully automated and allows to regulate the conditions of the synthesis process, therefore different types of zeolite materials (including: Na-X, Linde-A, and Na-P1) can be obtained using the same equipment.

“…The ratio of silicone to aluminum used for the synthesis of the raw material influences the type of obtained zeolite. Moreover, factors such as the concentration and type of alkaline, temperature, pressure and reaction time determine the obtainment of different zeolites from the same fly ash [28].…”

Abstract. The combustion of municipal sewage sludge allows for the recovery of renewable energy. However, it simultaneously causes the formation of ash which is not neutral for the environment. The study presents the research on the possibility of using sewage sludge ash as a raw material for the synthesis of zeolites. The synthesis of zeolites was performed with the use of an indirect fusion method and a direct hydrothermal method. The research on sewage sludge ash after zeolitization included the identification of crystalized phases, the observation of changes of ash particles surface and the measurement of cation exchange capacity (CEC). The research results proved that optimal conditions for the formation of zeolite Y were the synthesis with the indirect fusion method at the sewage sludge ash to hydroxy sodalite ratio of 1:1.8, the activation temperature of 60 o C and the crystallization temperature of 90 o C. Hydroxy sodalite was found in samples from both methods of zeolitization. However, in the case of direct hydrothermal method, particles of hydroxy sodalite structure were less numerous indicating a small conversion of sewage sludge ash to crystalline zeolite. CEC values comparable to commercial zeolites resulted from zeolitization with the indirect fusion method.

“…Due to the high demand of the industry for synthetic zeolites, methods for producing these materials economically are still sought. In recent years, the feasibility of using fly ashes from hard coal and brown coal has been successfully studied (Chang,Shih 1998;Hollman et al 1999;Inada et al 2005;Derkowski 2006;Fotovat et al 2009;Belviso et al 2010;Franus et al 2014) as well as ash from fluid boilers (Grela et al 2016a, Grela et al 2016b for the synthesis of zeolite materials. Owing to intense studies, it is possible to discover new zeolite structures and to obtain thorough knowledge of their properties.…”

Characteristics of Sorbent Products Obtained by the Alkaline Activation of Waste from Waste Incineration Plants

Abstract. In Poland, by 2020 430,000 Mg of hazardous waste will be formed annually by the combustion of waste. This waste must be properly managed so as not to endanger the environment. One promising way to manage selected waste is to process it in the synthesis of materials characterised by sorption properties. The results presented in this paper concern the possibility of producing sorbents from waste materials marked with codes 190112 and 190114, which came from two waste incineration plants in Poland. Alkaline activation was performed using two methods: a) hydrothermal, in a solution of 8 M NaOH at 75°C for 24 h; and b) in an autoclave, using a solution of 2 M NaOH at 140°C for 6 h. XRD analyses led to the identification of materials after synthesis of the following zeolite phases: analcime, chabazite and thomsonite. chabazite and analcime can be valuable absorbent materials.
