  • 1 Estimating Profitability of Two Biochar Production Scenarios
    Estimating Profitability of Two Biochar Production Scenarios: Slow Pyrolysis vs. Fast Pyrolysis Tristan R. Brown1 *, Mark M. Wright2, 3, and Robert C. Brown2, 3 Iowa State University 1Biobased Industry Center 2Department of Mechanical Engineering 3Center for Sustainable Environmental Technologies * [email protected] Iowa State University Ames, IA 50011 Tel: (515) 460-0183 Fax: (515) 294-6336 ABSTRACT We estimate the profitability of producing biochar from crop residue (corn stover) for two scenarios. The first employs slow pyrolysis to generate biochar and pyrolysis gas and has the advantage of high yields of char (as much as 40 wt-%) but the disadvantage of producing a relatively low-value energy product (pyrolysis gas of modest heating value). The second scenario employs fast pyrolysis to maximize production of bio-oil with biochar and pyrolysis gas as lower-yielding co-products. The fast pyrolysis scenario produces a substantially higher value energy product than slow pyrolysis but at the cost of higher capital investment. We calculate the internal rate of return (IRR) for each scenario as functions of cost of feedstock and projected revenues for the pyrolysis facility. The assumed price range for delivered biomass feedstock is $0 to $83 per metric ton. The assumed carbon offset value for biochar ranges from $20 per metric ton of biochar in 2015 to $60 in 2030. The slow pyrolysis scenario in 2015 is not profitable at an assumed feedstock cost of $83 per metric ton. The fast pyrolysis scenario in 2015 yields 15% IRR with the same feedstock cost because gasoline refined from the bio-oil provides revenues of $2.96 per gallon gasoline equivalent.

  • Production of Metallurgical Charcoal from Biomass Pyrolysis: Pilot-Scale Experiment
    22nd International Symposium on Analytical and Applied Pyrolysis Kyoto, 2018 Production of metallurgical charcoal from biomass pyrolysis: pilot-scale experiment a a b b a A. Phounglamcheik *, R. Pitchot , A. Andefors , N. Norberg , and K. Umeki * corresponding author: [email protected] a Division of Energy Science, Luleå University of Technology, SE-971 87 Luleå, Sweden b Future Eco North Sweden AB, SE-961 50 Boden, Sweden Replacement of fossil coal with biomass fuel is a key strategy to decrease CO2 emission in the Nordic industry. Charcoal produced from pyrolysis of forest residue is expected for the application in metallurgical process. Quality of charcoal can reach the requirement, i.e. high carbon content, low volatile, low ash content, and high heating value at high pyrolysis temperature. Nevertheless, to produce charcoal with such high quality, the products distribution may shift toward pyrolysis oil and gas. We have suggested to increase the charcoal yield while keeping its quality by adsorbing large molecule fractions of pyrolysis oil on the pore structure of charcoal produced at relatively high temperature (>600 °C). This study aims at demonstrating the suggested pyrolysis process to produce metallurgical charcoal with high efficiency. The effect of various operation parameters was investigated in batch operations with ca. 130 kg dry wood chips for this purpose. The experiment was conducted in a pilot-scale auger-type pyrolysis reactor. Two cylindrical pipes with screw conveyers and external heating/cooling media are connected for pyrolysis and vapor adsorption. In the pyrolysis reactor, woodchips are heated indirectly with flue gas generated from a propane burner. In the vapor adsorption pipe, charcoal and volatiles are cooled down and part of pyrolysis volatile is condensed and absorbed on the surface of charcoal.

The pyrolysis oil yields of raw pine bark, pine, and Douglas-Fir bark at 500 ◦C were 29.18%, 26.67%, and 26.65%, respectively. Both energy densification ratios (1.32–1.56) and energy yields (48.40–54.31%) of char are higher than pyrolysis oils (energy densification ratios: 1.13–1.19, energy yields: 30.16–34.42%). The pyrolysis oils have higher heating values (~25 MJ/kg) than bio-oils (~20 MJ/kg) from wood and agricultural residues, and the higher heating values of char (~31 MJ/kg) are comparable to that of many commercial coals. The elemental analysis indicated that the lower O/C value and higher H/C value represent a more valuable source of energy for pyrolysis oils than biomass.

  • Study on Phenolic Content in Fast Pyrolysis Oil Obtained from the Model Compounds of Three Major Components in Biomass
    The 2016 International Conference on Advances in Energy, Environment and Chemical Science (AEECS 2016) Study on Phenolic Content in Fast Pyrolysis Oil Obtained from the Model Compounds of Three Major Components in Biomass Liu Ziyun1, 2, a, Wang Lihong1, 2, b, Li Yongjun1, 2, c and Li Zhihe1, 2, d 1School of Agricultural and Food Engineering, Shandong University of Technology, China, 2Shandong Research Center of Engineering and Technology for Clean Energy, Zibo 255049, Shandong Province, China; [email protected] [email protected] [email protected] [email protected] Keywords: cellulose; xylan; lignin; pyrolysis; phenolic compounds Abstract. The aim of this paper is to research variation of phenolic yields in bio-oil and the effect of interactions of three components in biomass, fast pyrolysis experiments were done with cellulose, xylan (as an alternative to hemicellulose) and lignin in tube furnace at different temperatures. Phenolic yields in liquid product analyzed by using Gas chromatography-Mass spectrometry (GC-MS) were divided into four groups: phenols, H-phenols, G-phenols and S-phenols. In single component oil, S-phenols yeild was hardly any. There were trends for phenols, H-phenols and G-phenols that were consistent with temperature increasing from 450 to 550℃. And in cellulose oil, H-phenols was prone to dehydroxylation near 500℃ . The phenolic compounds yields in lignin oil reached 25.98% at 550℃. For two-component oil, the yields of phenols and G-phenols increased due to the interaction of cellulose-lignin, while that of H-phenols decreased. The interaction of xylan-lignin was similar with cellulose-lignin.

  • Effect of Biochar on the Cracking of Tar from the Pyrolysis of a Pine Sawdust in a Fixed Bed Reactor Z.Z
    Available online at www.sciencedirect.com ScienceDirect Energy Procedia 75 ( 2015 ) 196 – 201 The 7th International Conference on Applied Energy – ICAE2015 Effect of Biochar on the Cracking of Tar from the Pyrolysis of a Pine Sawdust in a Fixed Bed Reactor Z.Z. Zhang, M.M. Zhu*, P.F. Liu, W.C. Wan, W.X. Zhou, Y.L. Chan and D.K. Zhang Centre for Energy (M473), The University of Western Australia, 35 Stirling Highway, Crawley, WA 6009, Australia Abstract The effect of biochar on the cracking of the tar from pyrolysis of a pine sawdust was experimentally studied. The pine sawdust was pyrolyzed in a fixed bed reactor at 1123K with and without a pine sawdust biochar placed downstream of the pyrolysis process to crack the pyrolysis tar. The cracking temperatures tested were 923, 1023 and 1123K and the vapour residence times of the tar passing through the biochar studied were 0, 1.2, 2.3 and 3.8s. The pyrolysis liquid yield decreased and pyrolysis gas yield increased with increasing biochar cracking temperature and the vapour residence time. The main pyrolysis gases were H2, CO, CH4 and CO2. As the cracking temperature increased, the H2 yield increased while CH4 yield decreased. The CO concentration decreased when the cracking temperature increased from 973K to 1023K but then increased when the temperature continued to increase. The trend of the change of CO2 concentration as a function of the cracking temperature was opposite to that of CO. As the vapour residence time increased, the yields of H2 and CO2 increased while CH4 and CO yields decreased.
