Abstract:The aim of this study was to investigate a possibility of synthesis of porous
ceramics with controlled open porosity, which could be used as sorbents and
catalyst supports. Two organic additives were used to obtain open porosity:
polystyrene beads and cellulose fibers, which are mixed with kaolin clay
powder and the appropriate water content. Samples were sintered at 1050?C
for 1h. Characterization of the obtained products included X-ray powder
diffraction analysis (XRPD), Fourier-transform i… Show more
“…As an example, C deposition in the CO 2 methane reforming cannot be eliminated, but it can be significantly reduced by high dispersion of small catalytically active particles and promoting of the catalyst. It is important to use or develop catalyst supports based on ceramics or other, that possess high controlled open porosity which would enable good dispersion of active particles (Al-Fatesh et al 2021, Nikolić et al 2022, Nikolić et al 2023. Ou et al (2021) have investigated Ni/perovskite catalysts for obtaining of H 2 by steam CH 4 reforming.…”

Blast Furnace (BF) process is dominant in the iromaking industry in the World. Growing demand for steelmaking raw materials results in fast consumption of fossil fuels, which are required for the BF operation and also serve as reducing agents. To lower the carbon footprint and achieve sustainable development, as well as circular economy, there is an increased need for using alternative reducing agents for BFs, such as waste plastics, bio-based materials etc. Those materials can be recycled or upcycled by utilization in BF process. Catalytic recycling/upcycling of exhaust gases was proposed, as it could be highly profitable, and, as well lower the carbon footprint of the BF process.
