“…The calculated total output of liquid fuels after upgrading of FP intermediate was 0.5 MJ/ MJ wood fuel feed-in (for LR) and 0.6 MJ/MJ wood fuel feed-in (for SD). These values can be compared to data from other studies of 0.53-0.59 MJ/MJ wood fuel feed-in [36,42,50,54,55]. The upgraded liquid fuel yield for HTL intermediate was 0.62 MJ/MJ wood fuel feed-in .…”

“…The literature study revealed a wide range of the data on hydrogen demand for upgrading. The hydrogen gas (H 2 ) demand for upgrading of the liquid intermediate from FP ranged from 0.21 to 0.32 MJ/MJ wood fuel feed-in [36,42,50,54,55], and for HTL, from 0.06 to 0.19 MJ/MJ wood fuel feed-in [42,48,49,51]. H 2 is added to favour oxygen removal by the hydrodeoxygenation pathway, where no carbon is lost from the hydrocarbons, and oxygen is removed as water.…”

“…Comparisons of these findings with results in the literature are difficult, as the results of previously published studies on biojet fuel production from other types of feedstock that include cultivation or land use change [8] are not relevant. Also, results based on LCA using other calculation principles cannot be used for comparison [42,54].…”

“…The calculations and input data on hydrogen demand are presented in Tables 7-9. [36,54,58], and no information can be extracted on co-product formation or pyrolysis energy demand. The data used for intermediate production are given in boldface in Table 7 and were chosen due to their transparency, and the possibility to create a dataset with non-integrated energy flows [31].…”

The transition from fossil jet fuel to biojet fuel is an important step towards reducing greenhouse gas (GHG) emissions from aviation. To enable such a fuel shift, the Swedish Government introduced a GHG emission reduction mandate of 27% by 2030 for aviation fuel sold in Sweden, forcing fuel suppliers to blend in biojet fuel in fossil jet fuel. A similar policy instrument is being discussed within the EU. Biojet fuels with life cycle GHG emissions 90% lower than those for fossil jet fuel are projected to be available by 2025, which by far exceeds the requirement of 65% lower emissions in the EU Renewable Energy Directive. The purpose of this study was to carry out life cycle assessments for a number of wood-fuel-based production chains near commercialization and to determine whether they meet the Swedish projection and the EU requirement. The study illustrates what can be achieved in a region with high availability of wood fuels and access to heat and power with low GHG emissions. The production chains studied include the production of hydrocarbon intermediates via (i) fast pyrolysis, (ii) hydrothermal liquefaction, (iii) thermal gasification followed by Fischer–Tropsch-synthesis, and (iv) cellulosic ethanol fermentation followed by upgrading of these four intermediates to biojet fuel and other liquid biofuels. The results show that all the production chains studied can deliver biojet fuels with 89–91% lower GHG emissions than fossil jet fuels. Non-fossil hydrogen is required to achieve low emissions in the upgrading of intermediates from fast pyrolysis and hydrothermal liquefaction.

Materials, fuels, upgrading, economy, and life cycle assessment of the pyrolysis of algal and lignocellulosic biomass: a review

et al. 2023

Climate change issues are calling for advanced methods to produce materials and fuels in a carbon–neutral and circular way. For instance, biomass pyrolysis has been intensely investigated during the last years. Here we review the pyrolysis of algal and lignocellulosic biomass with focus on pyrolysis products and mechanisms, oil upgrading, combining pyrolysis and anaerobic digestion, economy, and life cycle assessment. Products include oil, gas, and biochar. Upgrading techniques comprise hot vapor filtration, solvent addition, emulsification, esterification and transesterification, hydrotreatment, steam reforming, and the use of supercritical fluids. We examined the economic viability in terms of profitability, internal rate of return, return on investment, carbon removal service, product pricing, and net present value. We also reviewed 20 recent studies of life cycle assessment. We found that the pyrolysis method highly influenced product yield, ranging from 9.07 to 40.59% for oil, from 10.1 to 41.25% for biochar, and from 11.93 to 28.16% for syngas. Feedstock type, pyrolytic temperature, heating rate, and reaction retention time were the main factors controlling the distribution of pyrolysis products. Pyrolysis mechanisms include bond breaking, cracking, polymerization and re-polymerization, and fragmentation. Biochar from residual forestry could sequester 2.74 tons of carbon dioxide equivalent per ton biochar when applied to the soil and has thus the potential to remove 0.2–2.75 gigatons of atmospheric carbon dioxide annually. The generation of biochar and bio-oil from the pyrolysis process is estimated to be economically feasible.

A review of Canadian wood conversion technologies for the production of fuels and chemicals

et al. 2023

Canada has 347 million ha of forest cover, contributing to the potential large availability of wood‐based resources. Although Canada's forest sector contributed $23.7 billion to the national nominal gross domestic product (GDP) in 2019, the GDP contribution of the wood product manufacturing subsector shrank by 6%. To reposition the Canadian forest industry, new forest management practices and wood‐based conversion technologies should be applied. In this context, the use of woody biomass in biorefineries to produce clean energy, fuels, and chemicals is becoming increasingly significant. There is a need to understand the current status and challenges of the wood‐based biomass conversion technologies that have been and are being developed in Canada. This information will help decision‐makers in formulating and implementing forest sector‐related policies for a sustainable bioeconomy in Canada. This study is focused on a review of Canadian woody biomass conversion technologies. Our critical review identified considerable potential biomass conversion technologies specialized for woody feedstock, all in the Canadian setting. We focused on the prospects of revitalizing Canada's pulp and paper industry through the integration of pre‐treatment processes and biochemical technologies. The thermochemical conversion pathway was identified as the dominant route for woody feedstock valorization. The review also identified pathways with the potential to diversify the existing product mix that generate products from wood streams, such as chemicals and biomaterials. Most of the biochemical and thermochemical research done in institutional and multi‐institutional research collaborations from laboratory scale to industrial scale will boost the chances of the commercialization of a wood‐based biorefinery in Canada.
