| Outline of Final Research Achievements |
In this study, a life cycle analysis on bio-fuel production for the integrated biomass gasification SOFC system was conducted. In the operation of fuel cell system, the contaminants (e.g. hydrogen sulfide) have an impact to the performance. Thus, the influence of performance due to the contaminant was investigated. For the countermeasure, the chemical and physical adsorption was discussed on basis of experimental results.
Consequently, due to the impurity of H2S, the net energy efficiency of the fuel cell system varied 23.4 to 19.8%-LHV. From the viewpoint of LCA, the impact indexes of abiotic depletion and global warming were estimated. Due to lower consumption on metal catalysts and promotion of 2-step PSA operated at lower pressure which sequestrates CO2 gas simultaneously, the environmental benefits of 88.7% and 65.4% were obtained in comparison to the conventional concept.
