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} } @article{JankeWeinrichLeiteetal.2017, author = {Janke, Leandro and Weinrich, S{\"o}ren and Leite, Athaydes Francisco and Sch{\"u}ch, Andrea and Nikolausz, Marcell and Nelles, Michael and Stinner, Walter}, title = {Optimization of semi-continuous anaerobic digestion of sugarcane straw co-digested with filter cake: Effects of macronutrients supplementation on conversion kinetics}, series = {Bioresource Technology}, volume = {245}, journal = {Bioresource Technology}, issn = {0960-8524}, doi = {10.1016/j.biortech.2017.08.084}, pages = {35 -- 43}, year = {2017}, language = {en} } @article{JankeWeinrichLeiteetal.2019, author = {Janke, Leandro and Weinrich, S{\"o}ren and Leite, Athaydes Francisco and Str{\"a}uber, Heike and Nikolausz, Marcell and Nelles, Michael and Stinner, Walter}, title = {Pre-treatment of filter cake for anaerobic digestion in sugarcane biorefineries: Assessment of batch versus semi-continuous experiments}, series = {Renewable Energy}, volume = {143}, journal = {Renewable Energy}, issn = {0960-1481}, doi = {10.1016/j.renene.2019.05.029}, pages = {1416 -- 1426}, year = {2019}, language = {en} } @article{JankeWeinrichLeiteetal.2018, author = {Janke, Leandro and Weinrich, S{\"o}ren and Leite, Athaydes Francisco and Str{\"a}uber, Heike and Radetski, Claudemir M. and Nikolausz, Marcell and Nelles, Michael and Stinner, Walter}, title = {Year-round biogas production in sugarcane biorefineries: Process stability, optimization and performance of a two-stage reactor system}, series = {Energy Conversion and Management}, volume = {168}, journal = {Energy Conversion and Management}, issn = {0196-8904}, doi = {10.1016/j.enconman.2018.04.101}, pages = {188 -- 199}, year = {2018}, language = {en} } @article{JankeWeinrichLeiteetal.2017, author = {Janke, Leandro and Weinrich, S{\"o}ren and Leite, Athaydes Francisco and Terzariol, Filippi K. and Nikolausz, Marcell and Nelles, Michael and Stinner, Walter}, title = {Improving anaerobic digestion of sugarcane straw for methane production: Combined benefits of mechanical and sodium hydroxide pretreatment for process designing}, series = {Energy Conversion and Management}, volume = {141}, journal = {Energy Conversion and Management}, issn = {0196-8904}, doi = {10.1016/j.enconman.2016.09.083}, pages = {378 -- 389}, year = {2017}, language = {en} }
