Abstract
A method for producing biogas from biomass in a biogas reactor, wherein at least one standard value is provided for the concentration of at least one trace element in a biogas reactor for efficient biogas production, 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 the determined trace element concentration falls below the standard value, deficient trace elements are added to the biogas reactor.
Claims21
A method for producing biogas from biomass in a biogas reactor, wherein
- at least one standard value is provided for the concentration of at least one trace element in a biogas reactor for efficient biogas production,
- 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 the determined trace element concentration falls below the standard value, deficient trace elements are added to the biogas reactor:
- the standard values for nickel are 4 to 30 mg/kg DM and/or for cobalt 0.4 to 10 mg/kg DM and/or for molybdenum 0.05 to 16 mg/kg DM and/or for iron 750 to 5000 mg/kg DM.
