List of components and quantities available in biogas and biomethane

For siloxanes and terpenes, a lot of gas samples were analyzed. It turned out that seven siloxane components and four terpene components have been identified that are occasionally traced in biogas. Also a relation with the origin of the biomass and the formation of these compounds was made. These components should therefore be part of a reference gas. This innovation is part of a standard to be developed.
