Study on Rapid Gasification Characteristics of Refuse-Derived Fuel
To address the issue of slow heating rates in current refuse-derived fuel (RDF)gasification experiments,the rapid gasification characteristics of RDF under three atmospheres (oxygen,nitrogen,and steam)at five temperature points (500—900℃)are investigated.Results show that O
2
exhibits strong oxidizing properties,leading to significant CO
2
production and the lowest gas generation potential.Under CO
2
atmosphere,the Boudouard reaction dominates,yielding considerable syngas but limited by its single reaction pathway.In contrast,the steam atmosphere enables high gas production rates through multiple synergistic mechanisms,achieving the best gasification performance with a total gas yield of 16.7 mmol·g
-1
,far exceeding that of O
2
and CO
2
,demonstrating the superiority of steam in rapid RDF gasification.As the temperature increases,the tar components from gasification exhibit a forward shift in composition.Under O
tion.In the steam atmosphere,solid residues contain heterocyclic structures,and high temperatures inhibit recombination,leading to an increased proportion of light hydrocarbons.
