The role of digestate disintegration in anaerobic digestion KU Leuven
Anaerobic digestion is a biological process that converts organic wastes into energy rich biogas and nutrient rich digestate. The produced biogas can be valorised on site as electricity and heat, or it can be upgraded into methane and used in existing methane grids or used as transportation fuel. The hydrolysis step is generally regarded as the rate-limiting step of anaerobic digestion. In this research, the effect digestate disintegration ...
Stripping and scrubbing of ammonium using common fractionating columns to prove ammonium inhibition during anaerobic digestion KU Leuven Ghent University
Anaerobic digestion to produce biogas is generally considered as one of the most sustainable technologies for the production of renewable energy. During this microbial process, organically bound nitrogen is released as ammonium that ends up in the digestate and fnally may inhibit the process. In this study, it is investigated if ammonium can be removed and recovered out of the liquid fraction of a thermophilic digestate from a potato processor. ...
Optimization of hydrothermal conversion of bamboo (Phyllostachys aureosulcata) to levulinic acid via response surface methodology KU Leuven
In this study, the dilute acid hydrolysis of lignocellulosic bamboo (Phyllostachys aureosulcata) particles to levulinic acid in a hydrothermal synthesis reactor is reported. The aim of the study was to optimize the reaction conditions for maximum levulinic acid production in terms of reaction time (t), reaction temperature (T) and HCl concentration (cHCl) via Response Surface Methodology (RSM). A maximum levulinic acid yield of 9.46 w% was ...
