Węgiel kamienny jako surowiec naturalny jest bardzo zróżnicowany pod względem właściwości fizykochemicznych i opałowych, co skutkuje różnicami emisji szkodliwych zanieczyszczeń gazowych do atmosfery w trakcie procesu spalania. Autorzy porównują dwa typy węgla kamiennego 'Julian' z Górnośląskiego Zagłębia Węglowego i 'Bogdanka' z Lubelskiego Zagłębia Węglowego oraz emisje SO2 powstającego w trakcie spalania tych węgli, a także przedstawiają metodę zmniejszenia tych emisji przy zastosowaniu katalizatorów spalania.

The paper present the influence of hard coal type on an emission of sulphur dioxide produced in the combustion of coal from different coal from the main 'Julian' and 'Bogdanka'. The use of active material of DESONOX catalyst may drastically decrease SO2 emission in the range 44-90%.

A method for removing SO2 from flue gases is described, which is quite different from classical wet desulphurization methods. The effect of the preparation technique on the physico-chemical properties of desonox catalysts is described. The influence of the total surface area and other physico-chemical properties of the catalyst on its behavior is discussed.

Combustion of coal in its unprocessed form is an emission source of environmentally toxic compounds. Thise emissions are higher when both the efficiency of combustion process and the technical abilities of flue gas purifying are low, thus making the quality of combusted fuels veryimportant. The highest emissions result from fuel combustion in individual domestic appliances and municipal small-power industrial units. Besides the particulate emissions (soot, fly ash) and gases (CO2, CO, SO2, NOx), flue gases also contain organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), dioxins, furans, POPs (persistent organic pollutants), aliphatic hydrocarbons, benzene and its homologues, aldehydes and ketones, VOCs, phenol and its alkyl derivatives, heterocompounds of sulfur and nitrogen, and heavy metals. The paper presents results of a study on the abatement of pollution emission from solid fuel combustion tests with DESONOX catalyst addn. Combustion tests were carried out in small domestic appliances. Investigations proved that addition of DESONOX catalyst to compacted fuel, significantly decreases not only NOx and SO2 emission, but also the emission of organic compdounds (VOCs and 16 PAHs according to EPA).
