Bio-methane via fast pyrolysis of biomass

Exergoeconomic assessment of CHP-integrated biomass upgrading

“…Rogers and Brammer [8] stated the production of bio-oil to be profitable at the current oil price level which is in line with the recent commissioning of the CHP-integrated pyrolysis oil production plant in Joensuu, Finland by Fortum [9]. For further upgrading of pyrolysis products Görling et al suggested bio-methane synthesis [10]. More general, Djuric Ilic et al [11] found that when biofuel production is integrated with DH generation, biofuels can be produced at prices competitive with fossil transport fuels.…”

Production of solid fuel biochar from waste biomass by low temperature pyrolysis

“…The distributions and properties of these product streams are strongly dependent on pyrolysis conditions. Currently most attention is paid to the liquid and gaseous products, and many techniques and processes have been developed to increase the yield and improve the quality of these two target products [4][5][6][7][8]. However, due to the high instability and complex composition, bio-oil cannot be used directly, but requires further upgrading [4].…”

Bio-methane upgrading of pyrolysis gas from charcoal production

“…The pyrolysis vapour case theoretically has a higher total efficiency (73%) compared to gasification (69%) (results from [10] recalculated to biomass basis in [12]) and the authors' previous study via fast pyrolysis (74%) [12]. However, it is not trivial to compare processes with different types of inputs and outputs; it is therefore mainly to be considered an indication of the potential of the process.…”

“…In Sweden, bio-methane is also a prioritized renewable fuel for the transport sector and is subsidized with, for example, exemption from energy and carbon dioxide taxes. The authors of this paper have previously studied the production of bio-methane via fast pyrolysis [12]. The main finding from that study was that the production route has a high overall energy efficiency, which may be further increased by reducing the power demand.…”

“…The biomass to methane energy yield via gasification amounts to 64-67% [10], excluding the power demand and by-products. When the by-products (char and tar) and the power demand are included, the total efficiency increases to 69% (from [10], results re-calculated on a biomass basis in [12]). Several production routes via fast pyrolysis leading to different transport fuels have been suggested (reviewed in [13][14][15]), e.g.…”
