Experimental studies have been carried out using an adsorber – a constructed laboratory bench. Zeolite, a natural mineral, has been selected as a charge. This aluminosilicate of a crystalline structure is resistant to high temperatures, aggressive mediums and the impact of radiation. Zeolite is ecologically clean, inert and non-toxic material, which fully suits to be used in most industrial, agricultural, environment fields and at home for eliminating the consequences of ecological accidents etc. For the purification of contaminated biogas, the laboratory adsorber is equipped with three sections filled up with 10 cm of adsorbing material the efficiency of which is established after every filtration column (10 cm, 20 cm and 30 cm). The studies have been carried employing two different contaminants – sulphur hydrogen (H2S) and ammonia (NH3). It has been established that, with a high concentration of sulphur hydrogen, the efficiency has amounted to 96.1% while the degree of ammonia purification has reached 95.4%,when NH3 concentration in biogas is 24.0 mg/m3.
