Study on gasification kinetics of refuse-derived fuel semi-cokes

ABSTRACT

Kinetic gasification of refuse-derived fuel (RDF) semi-cokes was studied by use of a thermogravimetric analyzer, under the condition of CO₂ atmosphere. The results show that: with the heating rate increasing, the weightlessness reaction rate increases; the reactivity of semi-cokes gasification is the best at 20°C/min, because the reaction activation energy is the lowest at the heating rate of 20°C/min; with the gasification temperature increasing, it is good for the gasification of RDF semi-cokes and the carbon conversion time-advance; for the different material ratios of RDF semi-cokes, the reactivity decreases with the contents of biomass reducing and the waste contents increasing.
