摘要

This paper studied the gasification of two solid recovered fuels (SRF) in a laboratory scale fluidizedrnbed reactor. The gasification performance and syngas quality were assessed under the influence of severalrnparameters: gasification temperature (from 700 to 850 ℃), equivalence ratio (ER, 0.22-0.35), SRF feedstock (RT orrnFL), bed material (sand or dolomite) and gasification agent (air or oxygen/steam). Special attention was devoted tornthe evolution of tar and microcontaminants concentration (H_2S, HCN, HCl and NH_3) in the syngas. The resultsrnindicated that increasing gasification temperature and ER led to higher gas yields and H_2/CO ratios whereas tarrncontent decreased. In general, the predominant levels of HCl and HCN in the producer gas tended to diminish at thesernconditions meanwhile H_2S slightly increased and NH_3 was scarcely detected. Other parameters affecting positivelyrnthe gasification performance were the use of dolomite as bed material and the use of oxygen/steam as gasificationrnagent, enhancing tar cracking and reforming reactions. This study provides insight into the evolution of the studiedrnmicrocontaminants under different experimental conditions and reports recommendations about the gasificationrnconditions in order to improve gasification performance and gas quality for two different SRF.
