Optimering av biogasproduktion från gödsel / Optimization of Biogas Production from Manure

Özdemir, Gonca January 2009 (has links)
<p>                      In this study, the bioconversion of manure and silage to biogas by an anaerobic digestion process in batch reactors was studied. Biogas is a valuable alternative energy source, mainly in rural areas. The main aim for the environment is to use biogas as a fuel instead of crude oil or natural gas. In this study, two different parameters were studied to observe the changes in methane productivity. The first three reactors were shaken once per week and the following three reactors were shaken 5 times per week. The results showed that mixing has no major effect on the methane production yield. In the second six reactors a mixture of 1% and 3% silage was added and the results were recorded. When the data from the reactors with just manure was compared to the reactors with 1% and 3% silage, it was seen that the silage increased the production rate and total gas produced. The process stabilization took a long time for digestion with the 3% silage possibly caused by release of too much fatty acids.</p>

Biomasseaufbereitung zur Vergärung - Aufarbeitung landwirtschaftlicher Biomasse für den Vergärungsprozess

Weiß, Daniel, Brückner, Claudia 23 July 2008 (has links) (PDF)
Die Studie »Aufarbeitung landwirtschaftlicher Biomasse für den Vergärungsprozess« zeigt, dass eine dem Vergärungsprozess vorgeschaltete Aufarbeitung landwirtschaftlicher Biomasse mittels Doppelschneckenextruder, Multischroter oder Enzymen die Energieproduktion um bis zu 26,6 % steigern kann. Die beispielhafte Darstellung von Aufarbeitungsmöglichkeiten anhand einer Biogasanlage mit 500 kWel beweist, dass sich die Biogaserzeugung beim Einsatz von Maissilage lohnen kann. Eine Rentabilitätserhöhung ist dabei kaum ersichtlich, es kann jedoch mit frei werdender Anbaufläche für die Nahrungsmittelproduktion gerechnet werden. Eine wirtschaftliche Biogaserzeugung auf der Basis vorzerkleinerter Grassilagen konnte nicht nachgewiesen werden, lediglich eine deutliche Effizienzsteigerung. Wie sich die Gewinnerwartung bei zunehmendem Gülleanteil bei Grassilage verhält sowie ausführliche Betrachtungen der Versuche und deren Wertung lesen Sie im kompletten Ergebnisbericht.
