BIOGAS, AS ONE OF THE TYPES OF PROMISING BIOLOGICAL FUEL

Biogas is a combustible gas produced during the anaerobic methane fermentation of biomass and mainly consists of methane (55-75%), carbon dioxide (25-45%) and impurities such as hydrogen sulphide, ammonia and nitrogen oxides (less than 1 %) is. substance. Decomposition of biomass occurs mainly as a result of chemical and physical processes and symbiotic life activity of three groups of bacteria, which are shown in fig. 1., while the products of metabolism of some are food products of others in a certain sequence [1, 7].
