ABSTRACT
This article presents the results of the research in the area of the possibilities of the utillisation of the natural zeolite from the locality Nižny Hrabovec at reduction of combustion engines toxical gases. The combustion engines produce a lot of toxical emissions. There is an increased interest to utilize zeolites in the partial reduction of CO, NOx and hydrocarbons in the combustion products in the world. The article contains the results of the measurements obtained by testing of the filter-sorption machinery with natural and modify zeolite. The influence of the chemical treatment on the sorptional and catalytical possibilities of natural zeolite was acknowledge with experiments.

W artykule przedstawiono wyniki badań nad możliwością wykorzystania naturalnego zeolitu-klinoptilolitu – pochodzącego z Nižnego Hrabovca na Słowacji do redukcji ilości toksycznych zanieczyszceń w spalinach z silników spalinowych. Klinoptilolit jest to minerał z gromady krzemianów, zaliczany do grupy zeolitów, odmiana heulandytu o składzie (Na, K)4 Ca (Al6 Si30 O72) ź 24 H2O. Należy do grupy minerałów rzadkich. W świecie wzrasta zastosowanie zeolitów do częściowej redukcji CO, NOx i węglowodorów w produktach spalania. W artykule przedstawiono wyniki badań nad sorpcją zanieczyszczeń przez zeolity w instalacji laboratoryjnej. Współczynnik efektywności sorpcyjnej określono zgodnie ze wzorem: Efektywność (%) = [(c1 – c2)/c1] ź 100 gdzie: c1 — zawartość NO w gazach odlotowych na wejściu do filtra c2 — zawartość NO w gazach odlotowych na wyjściu filtra Zbadano sorpcję na zeolicie naturalnym oraz modyfikowanym. Modyfikacja zeolitu polegała na obróbce termicznej, obróbce CoCl2 i NH4Cl.
