摘要

Results of experimental research for waste to energy production using integrated thermal-chemical process with alternative fuels generation are presented in this paper. Although various technologies for thermal-chemical conversion of waste (i.e. gasification, pyrolysis) were developed during the last years, the most used technique it is still based on combustion. The high air excess required for the complete solid wastes oxidation is the main cause of the combustion global energy efficiency limitation due to the process high outgoing hot gases flow ratio. Nevertheless, the high treatment temperatures and the massive presence of the oxygen facilitate the nitrogen toxic components and the flying ash transport, forcing the industrials to costly gases flue treatment utilities. In the last decade many research centers started to reconsider alternative thermal treatment technologies as pyrolysis and gasification applied to waste for alternative fuels production. Alternative waste to energy conversion focused on thermal engines, gas engines and fuel cells. There is a real interest in maximizing the syngas low heating value or the hydrogen content. Therefore our research focused on optimizing the vapor-gasification process. The results of waste thermal degradation can by applied on a large range of products with useful energy content (industrial and urban wastes, sludge etc.). Research focused on: waste “energy quality“ improvement by pyrolysis process, syngas with increased hydrogen content production using vapor-gasification, process kinetics. The aim of the research was the optimization of two-stage conversion process using a versatile bench tubular reactor and reconstituted MSW samples. The conducted processes were low, medium and high temperature pyrolysis (500 °C, 650 °C, and 800 °C,) and high temperature vapor-gasification (800–1000°C,). The derived fuels obtained were used for electrical energy generation through different energy conversion cycles.
