The paper presents results of a study on obtaining N-enriched active carbons from Polish brown coal and on their use as adsorbents for removal of pollution from gas phase. The crushed precursor was subjected to carbonisation at 500, 600 and 700°C in argon atmosphere. The chars obtained were activated by KOH at 800°C. The active carbons were further subjected to the ammoxidation at 350°C for 3 h, by a mixture of ammonia and air at the ratio of 1:3. The final products were microporous active carbons of well-developed surface area reaching to 2849 m^2/g and pore volume to 1.49 cm^3/g, showing mixed acid-base character of the surface. The results have shown that a suitable choice of the carbonisation, activation and ammoxidation procedures for brown coal can lead to obtaining activated carbons with high nitrogen dioxide adsorption ability, reaching from 16.9 to 36.4 mg NO_2/g.
