Sodium hydroxide (NaOH) pretreatment at different concentrations was investigated in batch experiments and the cumulative methane yields fitted to a dual-pool two-step model to provide an initial assessment on AD. The effects of nitrogen supplementation in form of urea and NaOH pretreatment for improved VFA production were evaluated in a semi-continuously operated reactor as well. The results indicated that higher NaOH concentrations during pretreatment accelerated the AD process and increased methane production in batch experiments. Nitrogen supplementation resulted in a VFA loss due to methane formation by buffering the pH value at nearly neutral conditions (∼6.7). However, the alkaline pretreatment with 6 g NaOH/100 g FCFM improved both the COD solubilization and the VFA yield by 37\%, mainly consisted by n-butyric and acetic acids.}, language = {en} } @incollection{DieckmannEdelmannKaltschmittetal.2016, author = {Dieckmann, Christiane and Edelmann, Werner and Kaltschmitt, Martin and Liebetrau, Jan and Oldenburg, Saskia and Ritzkowski, Marco and Scholwin, Frank and Str{\"a}uber, Heike and Weinrich, S{\"o}ren}, title = {Biogaserzeugung und -nutzung}, series = {Energie aus Biomasse}, booktitle = {Energie aus Biomasse}, publisher = {Springer}, isbn = {978-3-662-47437-2}, doi = {10.1007/978-3-662-47438-9_19}, pages = {1609 -- 1755}, year = {2016}, language = {de} }
