METHOD FOR PRODUCING BIOGAS IN CONTROLLED CONCENTRATIONS OF TRACE ELEMENTS

摘要

The invention relates to a method for producing biogas in a biogas reacto r, wherein at least one standard value for the concentration of at least one trace element is established in a biogas reactor for the effective producti on of biogas, the biogas is produced from biomass in the biogas reactor, the concentration of at least one trace element in the biomass is determined in the biogas reactor and in the event that said concentration is below the st andard value, absent trace elements are added to the biogas reactor through the determined trace element concentrates.
