Modellierung und Simulation des anaeroben Prozesses der Biogaserzeugung mit verschiedenen Substraten

Abstract

A simulation of the anaerobic process of a biogas production for different substrates was realized (manure, lipid rich substrate, organic waste and maissilage). The simulation was based on the Anaerobic Digestion Model No. 1 (ADM1). The experimental work comprehends batch-experiments and experiments in a continuous stirred-tank reactor at lab scale with different substrates used in a biogas production. The comparison between the experiments and the simulations of the process leads to a modification in ADM1. Furthermore a classification of substrates was developed according to their biodegradability to meet the fractions of the ADM1 simulation. The model was used for the simulation of a biogas plant fed with manure and food waste as substrates.

Es wird eine Simulation des anaeroben Prozesses in Biogasanlagen beschrieben, die es erlaubt den Prozess für den Einsatz verschiedener realer Substrate zu optimieren. Als Basis zur Modellierung wird das ADM1-Modell (Anaerobic Digestion Model No. 1) verwendet. Es wurden Batch-Versuche mit verschiedenen Substraten sowie Experimente in einem kontinuierlichen Laborreaktor durchgeführt. Anhand der experimentellen Ergebnisse erfolgten eine Parametrisierung und Modifikationen im Modell. Nach der Validierung des Modell im Labor wurde die Simulation einer großtechnischen Biogasanlage realisiert.
