Energy valorisation of citrus peel waste by torrefaction treatment
Result description
The article deals with the issue of processing and utilization of citrus peel, which often ends unused with other biodegradable waste. The research is concerned with the energy potential of this raw material and its torrefaction conversion. The tested materials were orange peel (Citrus sinensis Osbeck cv Valencia, Citrus sinensis Osbeck cv Murcia) and grapefruit peel (Citrus paradise Ruby red). Samples of dried materials underwent torrefaction treatment at 225 oC, 250 oC and 275 oC for 30 minutes. Samples before and after torrefaction were analysed for proximate and elemental composition and for calorific value. Consequently, stoichiometric combustion analyses were done. The torrefaction was performed in a LECO TGA 701 thermogravimetric analyzer under nitrogen atmosphere. The results of proximate and elemental analysis showed positive influence of torrefaction on the samples. The highest net calorific value for orange peel is 24,97 MJ kg-1 at the temperature of 275 oC. The greatest differences in net
