The combustion engines produce a lotoftoxical 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.}, title={Natural zeolite-clinoptilolite - raw material serviceable in the reduction of toxical components at combustion engines noxious gases}, type={Article}, URL={http://journals.pan.pl/Content/133723/PDF/4_GSM_23_4_2007_Macala_Natural.pdf}, keywords={clinoptilolite, noxious gases, nitrogen monooxide, combustion engines}, }
