Abstract
Gasification of solid waste biomass to generate synthesis gas and energy is an environmental alternative. Smuggled and seized cigarettes are part of the raw materials that can be used in gasification process, which allows the production of energy. Better results can be achieved by optimizing the operational parameters that require knowledge of some biomass characteristics, such as granulometry, immediate analysis, elemental and lower heating value (LHV). Samples that have moisture content ˂ 20% m/v, ash between 0.1 to 15% m/m, volatiles between 75 to 90% m/v and LHV between 15 to 20 MJ kg–1 are optimal for gasification. The analysis of smuggled cigarettes samples for all evaluated parameters revealed the following: 0.2 mm of wet cigarette granulometry presents, 10.1 ± 0.2 % m/v moisture, 65.7 ± 0.4 % m/v of volatiles and 12.9 ± 0.2 % m/m of ash, the LHV was 15.93 ± 0.01 MJ kg–1. The dry cigarette (in an oven at 105 oC for 72 hours) with the same granulometry presented 1.5 ± 0.1 % m/v humidity, 72.2 ± 0.6 % m/v volatiles, 12.4 ± 0.4 % m /m ash and LHV was 14.49 ± 0.06 MJ kg–1. The lower heating value of wet samples can be explained by the loss of mass/compounds present in the cigarettes due to volatilization during the drying process. In addition, the chemical composition of the synthesis gas was analyzed. It was found that of the main synthesis gas compounds (CO, CO2, H2, CH4), at 800 °C it favors greater formation of H2 (13.5% v/v) and at 670 °C it favors greater formation of CO (5.8% v/v) and CH4 (0.14% v/v). Based on these results, it is possible to conclude that smuggled cigarette gasification process can be applied in the generation of thermal and electrical energy. Furthermore, the process is strongly affected by temperature and humidity, thus highlighting the importance of optimizing the gasification operating parameters in order to improve the quality of synthesis gas for energy purposes.
