Abstract
Hydrothermal carbonization (HTC) was employed as an upgrading thermochemical conversion process for Refuse Derived Fuel (RDF). The effect of process temperature and residence time on the main characteristics of the produced hydrochars was studied. Results illustrated that the HTC process yielded hydrochars with upgraded characteristics such as reduced ash content (between 3.3 and 4.8 wt.%, db) and increased high heating value (between 25.2 and 28.1 MJ/kg, db) when compared with the original feedstock. Hydrochars also presented reduced chlorine contents, with the process reaching a chlorine reduction of 56 % at 300 ºC for 120 minutes. The produced hydrochars presented enhanced fuel properties when compared with the original RDF sample, as such, HTC could be applied as an upgrading tool for a very heterogenous and abundant fuel resource, that in most cases does not present adequate fuel characteristics.
