Design, Optimization and Energetic Efficiency of Producing Hydrogen-Rich Gas from Biomass Steam Gasification

Kuo, Po-Chih; Wu, Wei - In: Energies 8 (2014) 1, pp. 94-110

In this article, the conceptual design of biomass steam gasification (BSG) processes using raw oil palm (ROP) and torrefied oil palm (TOP) are examined in an Aspen Plus simulator. Through thermodynamic analysis, it is verified that the BSG process with torrefied feedstock can effectively enhance...

Life Cycle Assessment of Biochar<i> versus</i> Metal Catalysts Used in Syngas Cleaning

Frazier, Robert S.; Jin, Enze; Kumar, Ajay - In: Energies 8 (2015) 1, pp. 621-644

) study was performed to analyze the sustainability, via impact assessments, of producing a metal catalyst<i> versus</i> a … dedicated biochar catalyst. The LCA results indicate that biochar has a 93% reduction in greenhouse gas (GHG) emissions and … requires 95.7% less energy than the metal catalyst to produce. The study also estimated that biochar production would also have …

Lubrication Properties of Bio-Oil and Its Emulsions with Diesel Oil

Lu, Qiang; Zhang, Zhi-Bo; Liao, Hang-Tao; Yang, Xiao-Chu; … - In: Energies 5 (2012) 3, pp. 741-751

Bio-oil from fast pyrolysis of biomass is a low-grade liquid fuel, which can be upgraded through the emulsification with diesel oil. In this study, we prepared two rice husk bio-oil samples with different solid char contents and three bio-oil/diesel-oil emulsion samples with the bio-oil content...

Investigation on Electrostatical Breakup of Bio-Oil Droplets

Wang, Zhen-Tao; Mitrašinović, Aleksandar M.; Wen, John Z. - In: Energies 5 (2012) 11, pp. 4323-4339

In electrostatic atomization, the input electrical energy causes breaking up of the droplet surface by utilizing a mutual repulsion of net charges accumulating on that surface. In this work a number of key parameters controlling the bio-oil droplet breakup process are identified and these...
