Abstract [en]

Forest-based fast pyrolysis liquids constitute a potential low-sulphur fuel alternative for the marine sector. However, it is a challenge to meet the marine fuel quality demands set by current infrastructure, engines and fuels standards. The aim of this work has been to explore the potential for producing a new and more sustainable marine fuel quality. This new fuel quality is based on upgraded pyrolysis oil which is used as a fuel component in three-component blends. Low-water containing pine pyrolysis oil samples were formed by vacuum-assisted dewatering and in the next step three-component blends were prepared by mixing pyrolysis oil with bio-diesel and nbutanol. The results showed that less amount of butanol is required to form homogenous and storage stable blends when using dewatered pyrolysis oil as a blend component as compared to using crude pyrolysis oil. Dewatering also reduced the corrosiveness dramatically indicating that fuel blends based on dewatered pyrolysis oils are more compatible with marine engines than fuel blend based on crude pyrolysis oil.

Abstract [en]

The International Convention for the Prevention of Pollution from Ships (MARPOL) is reducing the allowed amount of sulphur in marine fuels and these reductions will continue in the future. Bio-oil is a sulphur-free liquid fuel and it constitutes a potential biofuel for the marine sector because it may be produced at industrial scale through pyrolysis of residues coming from the wood processing industry. Due to some of its challenging characteristics, it cannot substitute conventional fuels directly or be blended with them, but it might be used as a component of an emulsified drop-in fuel. The objective of this work is to determine the best conditions to produce an emulsified marine drop-in fuel. These conditions include the percentages of each component (marine gas oil or biodiesel, bio-oil, surfactant, type and combination of surfactants and the hydrophilic-lipophilic value (HLB) of the surfactant blend. Stability of the emulsions has been analysed by light scattering and visual observation at different times. This work forms part of the ReShip Project partly funded by the Research Council of Norway (The ENERGIX programme).

Abstract [en]

The wood processing industry generates large amounts of forest residues like branches and tops which represent a significant unexploited resource for sustainable biofuel production. A feasible thermochemical route to valorise these residues is fast pyrolysis. However, the main product of this technology, pyrolysis oil or bio-oil, shows several disadvantages in comparison with conventional fuels. One of the main drawbacks of bio-oil is its instability which results in liquid phase separation in many cases. The purpose of this study is to verify whether homogenous single-phase heating fuels for district heating etc. can be formed from aged, phase separated forest residue pyrolysis oils by blending. Aged, phase separated pyrolysis oils were blended with either methanol or 1-butanol and the amount of alcohol needed to form homogeneous and storage stable fuel blends was evaluated. Homogeneity of the fuel blends was analysed by water concentration profile analysis and image analysis. Storage stability was analysed by analysing homogeneity as function of storage time. Essential fuel characteristics were analysed. The results revealed that phase separated forest residue pyrolysis oil can be homogenized by adding moderate amounts of alcohol and that some of the blends are stable longer than two months. Alcohol addition also improves essential product properties for pyrolysis oils as heating fuels. This work forms part of the ReShip Project partly funded by the Research Council of Norway (The ENERGIX programme).
