| dc.description.abstract | This research investigates feasibility of co-gasification of automobile shredder residue derived fuel (ASR-RDF) and paper mill sludge derived fuel (PMS-RDF). The conversion energy experiments were controlled at equilibrium ratio (ER) 0.3, gasification temperature 700°C, and ASR-PMS amended ratio (100:0, 83:17, 67:33, 56:44). To further discuss the air pollutants containing chlorine removal efficiency, Ca(OH)2 was used as the amendment to adjust 5%-15 wt.% in ASR and to capture the chloride derived from in-situ ASR gasification. The producer gas composition, product distribution, energy yield efficiency, pollutants containing chlorine partitioning characterization were all evaluated in this research. Based on the analysis results of produced gas composition in co-gasification, the syngas composition produced from 100% ASR-RDF was 3.39 vol.% in average. The heating value of syngas was approximately ranged between 0.37 MJ/Nm3 and 0.68 MJ/Nm3. However, in the case of 33% PMS-RDF addition (i.e. 67:33 amended ratio), the syngas composition was significantly increased to 5.11 vol.% in average. The heating value of syngas was also increased ranged from 0.64 to 1.59 MJ/Nm3. This is the synergistic effect on the enhancement of syngas heating value produced from ASR gasification. The chlorine concentration of the syngas was decreased from 0.28 ppm to 0.06 ppm with the PMS-RDF addition increasing. The chlorine removal efficiency was approximately 78.6%. On the other hand, in the case of adding 15% Ca(OH)2, the enhanced energy conversion efficiency was insignificantly in ASR gasification. However, the chlorine concentration of the syngas could also decrease from 0.28 ppm to 0.1 ppm with the Ca(OH)2 addition increasing. The chlorine removal efficiency was also reached to 64.3%. In summary, the results obtained from this research could provide the good information on enhanced the energy conversion efficiency, syngas composition, and inhibiting of the HCl concentration produced in co-gasification of ASR and PMS. It is also proved the amended Ca(OH)2 in ASR-RDF could effectively reduce the HCl emission in ASR gasification. Therefore, the results of this research could provide the technological considerations of selection in ASR co-gasification in the future. | en_US |
