Fly ash which has been separated from the flue gas stream as a result of fossil fuels combustion constitutes a huge amount of waste generated worldwide. Due to environmental problems, many directions of their rational use have been developed. Various attempts to convert fly ash into sorption materials, mainly synthetic zeolites, are conducted successfully. In this paper, an attempt was made to convert fly ash from lignite combustion from one of the Polish power plants, using alkaline hydrothermal synthesis. The primary phases in the fly ash were: quartz, gehlenite, mullite, hematite, feldspar, lime, anhydrite, occasionally grains of ZnO phase and pyrrhotite, glass and unburned fuel grains. As a result of hydrothermal synthesis a material containing new phases – pitiglianoite and tobermorite was obtained. Among the primary ash constituents, only gehlenite with an unburned organic substance, on which tobermorite with crystallized pitiglianoite was present. As a result of detailed testing of products after synthesis, it was found that among the tested grains: • two populations can be distinguished – grains containing MgO and Fe₂O₃ as well as grains containing Fe₂O₃ or MgO or containing none of these components, • the main quantitative component was pitiglianoite, • pitiglianoite was present in larger amounts in grains containing Fe₂O₃ or MgO or in the absence of both components than in grains in which Fe₂O₃ and MgO were found. The results of the study indicate that in post-synthesis products, the contribution of components were as follows: pitiglianoite – 39.5% mas., tobermorite – 54% mas., gehlenite – 3% mas. and organic substance – 3.5% mas.

Popioły lotne po separacji ze strumienia gazów spalinowych, powstałych ze spalania paliw kopalnych, stanowią ogromne ilości w światowej skali odpadów. Z uwagi na problemy środowiskowe opracowano wiele kierunków ich racjonalnego wykorzystania. Z powodzeniem podejmowane są różne próby wykorzystania popiołów lotnych do materiałów sorpcyjnych, głównie syntetycznych zeolitów. W niniejszej pracy podjęto próbę wykorzystania popiołu lotnego pochodzącego ze spalania węgla brunatnego z jednej z polskich elektrowni, z zastosowaniem syntezy hydrotermalnej alkalicznej. W składzie mineralnym badanego popiołu lotnego stwierdzono obecność kwarcu, gehlenitu, mullitu, hematytu, skaleni, wapna, anhydrytu, sporadycznie ziaren fazy ZnO i pirotynu, szkliwa i ziaren nieprzepalonego paliwa. W materiale po hydrotermalnej syntezie popiołu lotnego stwierdzono obecność nowych faz – pitiglianoitu i tobermorytu. Wśród pierwotnych składników popiołu obecny był jedynie gehlenit z niespaloną substancją organiczną, na których krystalizowały nowe fazy. W wyniku szczegółowych badań produktów po syntezie stwierdzono, że wśród badanych ziaren: • można wyróżnić dwie populacje – ziarna zawierające MgO i Fe₂O₃ oraz ziarna zawierające Fe₂O₃ lub MgO lub niezawierające żadnego z tych składników, • głównym ilościowym składnikiem był pitiglianoit, • pitiglianoit obecny był w większych ilościach w ziarnach zawierających Fe₂O₃ lub MgO lub przy braku obu tych składników, niż w ziarnach, w których stwierdzono obecność Fe₂O₃ i MgO. Wyniki badań wskazują, że w produktach po syntezie udział składników był następujący: pitiglianoit – 39,5% mas., tobermoryt – 54% mas., gehlenit – 3% mas. i substancja organiczna – 3,5% mas.
