Dataset in the production of composite clay-zeolite membranes made from naturally occurring clay minerals

Abstract

The data presented in this article are generated as part of the research article entitled “from a naturally occurring material (clay mineral) to the production of porous ceramic membranes” (Elgamouz and Tijani, 2018) [1]. This article describe how clays as very abundant versatile materials that have many properties not available in pure materials namely, silica, alumina and zirconia can be used for the preparation of ceramic membranes (Karaborni et al., 1996; Oun et al., 2017; Hollanders et al., 2016; de Oliveira Henriques et al., 2017) [2], [3], [4], [5]. This paper presents data obtained at different stages of the fabrication of a clay-zeolite composite ceramic membrane made from a largely available clay from the central region of Morocco (Meknes). The data include the characterization of the clay powder using XRD, FTIR, thermogravimetric (TGA and TDA) analysis of the clay powder. The data of porosity, mesoporosity, specific surface area, volumes of the pores, volumes of mesopores, diameters of the pores using mercury intrusion porosimetry and adsorption desorption of nitrogen data that was computed from BET and BJH theories of the clay supports at different firing temperatures (700, 750, 800, 850 and 900 °C). Data obtained from measurement of nitrogen permeation of support alone and that of the silicalite membranes are also represented.

Characterization of the firing behaviour of an illite-kaolinite clay mineral and its potential use as membrane support

“…(Serra et al., 2013) attributed this phenomenon to pre-mullite spinal type phase formation that is not possible to detect in XRD. Similar phenomena were found when other clay minerals from different regions in Morocco were studied (Hajjaji et al., 2002; El Yakoubi, 2006; El Gamouz et al., 2007; Anbri et al., 2008; Azejjel et al., 2010; Elgamouz and Tijani, 2018, 2018a).

“…Based on results obtained from the X-ray diffraction, the raw clay minerals belong to kaolinite and illite type. Four (-OH) vibrations were characteristic; the first three bands (3700, 3670 and 3654 cm −1 ) were attributed to the stretching vibrations of surface hydroxyl groups, while the band at 3620 cm −1 was attributed to inner hydroxyl vibrations of the interlayer water (Frost and Mendelovici, 2006; El Gamouz et al., 2007; Anbri et al., 2008; Elgamouz and Tijani, 2018, 2018a). Such –OH vibrational peaks disappeared due to loss of adsorbed water at high temperatures.…”

“…(2014) have aimed to use a Cretaceous clay deposit (Moroccan Meseta) for the preparation of refractory products by compacting the material and centering it between 900 and 1000°C. However, choosing the right firing program requires a full investigation of the clay fraction in the clay mineral in addition, that different thermal phenomena which happen during the thermal analysis of the clay material must be identified and taken into consideration when designing a firing program (Elgamouz and Tijani, 2018, 2018a). This paper attempts to establish a correlation between Energy Disperse Spectroscopy (EDAX) elemental analysis, X-ray diffraction, thermal analysis (DTA and TGA), scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and methylene blue stain test as set by the French Association of Normalization (AFNOR) and the American Society for Testing and Materials (ASTM) (Chiappone et al., 2004).…”
