Preliminary determination of the suitability of slags resulting from coal gasification as a pozzolanic raw material / Wstępne Określenie Przydatności Żużli Ze Zgazowania Węgla Jako Surowca Pucolanowego

Abstract: Streszczenie Wymagania dotyczące ochrony środowiska, takie jak: ograniczenie emisji CO2, NOx i SO2 spowodowały coraz większe zainteresowanie nowymi technologiami energetycznego wykorzystania węgla. Jednąz testowanych i promowanych obecnie technologii jest zgazowanie węgla. Jednak, jak każda technologia produkcji energii wykorzystująca węgiel, powoduje ona powstawanie odpadów: popiołów lotnych i żużli. Ze względu na niewielką ilość instalacji zgazowania węgla funkcjonujących obecnie w świecie, odpady te są… Show more

“…This indicates practically lack of binding ability of these suspensions. This is also consistent with the results of the pozzolanic properties of such by-products of gasification (Mazurkiewicz et al, 2012). To use this type of materials to solidification backfill technology would be necessary to apply the binding materials such as cement.…”

“…In addition, researchers also selected other coal-based solid wastes for utilization [27]. Kaliyavaradhan et al reviewed the effects of solid wastes such as circulating fluidized bed combustion ash, ponded ash, slag, and BA on the strength of CLSM and suggested the mixing ratio of the mixed waste in CLSM [28].…”

“…The utilization of these slags and CO 2 still stands as a main challenge of the coal‐to‐chemicals industry. Slags from the coal‐to‐chemicals process are consisted of SiO 2 , Al 2 O 3 , CaSiO 3 , residual carbon, and so forth 2,3 . The major approach for slag treatment is landfills, and a small amount of slags is used to amend poor soils, 4 processed to be as building material (e.g., baking‐free brick 5 ) or as the raw material of cement clinker 1,6 .…”
