Disk membranes generated from high-purity natural clinoptilolite mineral rock have shown promising hydrogen separation performance. To scale up production of these types of membranes for industrial gas separation, a coating strategy was devised. A mixture of natural clinoptilolite and aluminum silicate was deposited on the inner surface of porous stainless steel tubes by the slip casting technique. Phase composition and morphology of the coating materials were investigated using X-ray diffraction. The performance was evaluated for a range of gases using single gas permeation tests at different temperatures and pressures. Introduction of the second layer significantly improved the performance of the membrane system. The experiments on the double-layered membranes measured a hydrogen permeance of 1.65 Â 10 À7 mol Á m À2 Á s À1 Á Pa À1 at 300 8C. H 2 /CO 2 and H 2 /C 2 H 6 single gas selectivity was 10.2 and 8.45 respectively at 25 8C and feed pressure of 110 kPa. These results show that natural zeolite coated stainless steel tubular membranes have high potential for large-scale gas separation at high temperature requirements.

“…Ceramic materials are divided into fibrous, granular, cellular and reticular according to their structural structure [9,10]. The following ways of establishing a porous structure in ceramic materials are distinguished: loose packing, bloating, using burn-out and other pore formers, monolithing and a combination of internal structures [11].…”

“…Combustion additives are of interest to industry because they offer a cost-effective and scalable method of creating porous ceramics. The ability to tailor the pore structure and size of porous ceramics using combustion additives can enable the production of materials with specific properties, such as high surface area, high permeability, and low thermal conductivity [9,23,24]. These properties make porous ceramics suitable for use in a wide range of applications, including catalysis, filtration, separation, and insulation.…”

The purpose of the study was to explore the effect of various pore-forming additives on the porosity and permeability of alumina ceramic material. Analysis of mineralogical, particle size distribution and chemical composition of raw materials and ceramics samples was performed using standard research methods, JCM-6000 (JEOL) and field emission scanning electron microscopy (FESEM) microscopes, LW600LT, x-ray diffractometer Rigaku D/max-RA, Hitachi SU-70 and Pore Master. The microstructure of the composite ceramic material in all experiments demonstrated the presence of numerous cross-sectionally elongated pores, which proves the dependence of the pore-forming structure on the shape of the pore-forming agent. The high permeability of samples with lignin is due to the improved plastic properties of the clays. By increasing the clay content from 5 to 10 wt.% it was possible to increase the sintering density of the samples and reduce their overall porosity. The permeability porosity increases with the introduction of more urea, and the strength of the samples is then at its maximum. Samples with the addition of lignin demonstrated resistance to mechanical stress and high permeability. The study identifies the prospects of using crystallised urea and lignin from manufacturing waste as a pore former, which will allow the establishment of environmentally friendly ceramic materials with high permeability and durability and solve the problem of atmospheric pollution.
