The use of biogas in the internal combustion engine (ICE) requires the purification of harmful impurities that reduce the quality of operation of the ICE fuel system. A filter device for biogas purification is presented. The zeolite from the Khonguruu deposit of Suntar ulus of the Republic of Sakha (Yakutia) has been tested as a filter to separate impurities. The results of a multifactor experiment on the main factors of the biogas purification process are given: the size of the fractions, the filtering material, its mass, the ratio of the bulk material height to the filter diameter. The best results on biogas purification were obtained at the ratios of the height and diameter H/d=3.0:4.2. The optimum weighted average diameter of granules of the bulk filter material (zeolite) was selected – 0.004 m. and mass of filter media – 0.75-0.8 kg. At these values, the maximum level of biogas purification is observed, where the methane content is 93.3%.
