Energy and Materials from Biomass Pyrolysis
F
lash pyrolysis is a thermochemical process to convert carbonaceous materials into oil, gas and char. Examples of carbonaceous
materials are biomass and waste streams. Unfortunately, the quality of the present pyrolysis oil from biomass is not good
enough for the existing infrastructure. There are in general two catalytic routes to improve the oil quality: deoxygenation or
hydrogenation. Deoxygenation will remove the oxygenated compounds from the oil but unfortunately with the removal of oxygen
also carbon is removed and thus the oil yield will be reduced. Via hydrogenation additional hydrogen has to be added to improve
the oil properties. However, because of the ample presence of oxygen in pyrolysis oil a lot of water is formed and moreover
expensive and mostly fossil hydrogen is required. A new idea presented here is aiming at a high-quality oil by simultaneously in-
situ catalytic deoxygenation and hydrogenation. A next step is the application of flash pyrolysis for the production of both energy
(biofuels) and materials. One example is paper sludge consisting of paper fibres and minerals. After drying and flash pyrolysis, the
fibres in the paper sludge are transformed into oil and flammable gas and the minerals can be used as a raw material for the paper
industry. Moreover, the paper industry can avoid dumping of this waste stream. This process of transforming biomass into fuels
and minerals is very promising for all kind of residues such as sewage sludge, manure, packaging material or waste streams. More
examples will be given during the presentation.
