Fractionation of Bio-Oil

Autor: Anja Oasmaa, Christian Lindfors, Eeva Kuoppala, Vesa Arpiainen, Yrjö Solantausta

Publikováno v: Lindfors, C, Kuoppala, E, Oasmaa, A, Solantausta, Y & Arpiainen, V 2014, ' Fractionation of bio-oil ', Energy & Fuels, vol. 28, no. 9, pp. 5785-5791 . https://doi.org/10.1021/ef500754d

The fuel properties of fast pyrolysis bio-oils differ significantly from those of fossil fuels. As transportation fuel, bio-oil is not suitable without upgrading because of its relatively low energy content, high water content, acidity, and poor stor

Fast Pyrolysis Bio-Oils from Wood and Agricultural Residues

Autor: Vesa Arpiainen, Yrjö Solantausta, Anja Oasmaa, Kai Sipilä, Eeva Kuoppala

Publikováno v: Oasmaa, A, Solantausta, Y, Arpiainen, V, Kuoppala, E & Sipilä, K 2010, ' Fast Pyrolysis Bio-Oils from Wood and Agricultural Residues ', Energy & Fuels, vol. 24, no. 2, pp. 1380-1388 . https://doi.org/10.1021/ef901107f

Fast pyrolysis bio-oil (pyrolysis liquid) from plant residues is one alternative to replace fossil fuels and feedstocks. Fast pyrolysis liquid is a potential source of revenues for companies who have biomass residues at their disposal. Once produced,

Light olefins and transport fuels from biomass residues via synthetic methanol: performance and cost analysis

Autor: Vesa Arpiainen, Ilkka Hannula

Publikováno v: Hannula, I & Arpiainen, V 2015, ' Light olefins and transport fuels from biomass residues via synthetic methanol: performance and cost analysis ', Biomass Conversion and Biorefinery, vol. 5, no. 1, pp. 63-74 . https://doi.org/10.1007/s13399-014-0123-9

A thermochemical processing route from biomass residues to light olefins (ethylene and propylene) is assessed by means of process simulation and cost analysis. A two-step process chain is proposed where (1) biomass residues are first converted to syn
