This postdoctoral position is part of a larger project demonstrating integrated production of methane and carbonised biomaterials from forest biomass. The main focus is on carbonisation of lignin and digestion residues using hydrothermal carbonisation (HTC), activation of the HTC chars, and chemical evaluation of the produced carbon materials.
This postdoctoral position is part of a larger research project where we will be demonstrating the integrated production of methane and carbonised biomaterials (biochar, activated carbon, and carbon fiber) from forest biomass. By organosolv pre-treatment of the biomass we can extract a lignin fraction isolated in high yield and high purity. The carbohydrate fraction from the pre-treatment will be used for the conversion of methane by digestion, while the lignin will be the feedstock for conversion to carbonised materials.
You will mainly work on the carbonisation of lignin and digestates by means of hydrothermal carbonisation (HTC). Some of the biochars be further refined to activated carbon and/or carbon fibres. You will both evaluate the way in which the chemical and physical properties of the biochars, activated carbons and carbon fibres are related to the origin and pre-treatment of forest-sourced raw materials, and also the performance of the carbonised materials as water purification adsorbents.
