Gaseificação em leito fixo de amostras de cigarros apreendidos

Abstract

The volume of seized materials has increased over the years and the proper disposal of these materials has been a challenge to environmental preservation as to the economic return to the State in these seizures. The present work aims to use a synthesis gas generated from seized cigarettes as fuel in the generation of electric energy. This analysis was performed using the equipment from the Laboratory of Heat and Mass Transfer at the Federal University of Uberlândia, which cigarette samples were submitted to calorimetry tests, thermogravimetric analysis, gasification and chromatography of the raw material and gases derived from the samples. It was possible to identify important properties such as calorific value, moisture content, volatile materials, ash and fixed carbon of the material. In addition, the chemical composition of the derived gas was analyzed as well as its energy potential linked to different power cycles. The results showed that the synthesis gases collected at 670 °C and 800 °C have a lower calorific value equal to 2371 kJ/kg and 77.59 kJ/kg, respectively. The Otto power cycle, using syngas collected at 670 °C, showed the highest efficiency (60.44 %) while the combined Brayton/Rankine cycle showed the highest ratio of mechanical energy produced per kilogram of syngas required (2134 kJ/ kg).
