Abstract

DIAZ, Gisela F. et al. Preliminary study of the energetic characterization of lemon pruning in the province of Tucumán. Rev. ind. agric. Tucumán [online]. 2017, vol.94, n.2, pp.71-74. ISSN 1851-3018.

The citrus industry in Tucumán holds leading positions worldwide. Currently the supply of natural gas to industry comes into deficit in harvest season; this can be solved with the use of crop residues. The aim of this work was to characterize energetically samples of fresh pruning and dry pruning from lemon cultivation in Tucuman. The results for green pruning were: 40.64% moisture; 2.68% ash; 79.52% volatile solids; 17.80% fixed carbon; 0.08% of total chlorine; 0.15% total sulfur; 18.329kJ / kg of high calorific value, and initial fusibility temperatures were higher than 1,500 °C. In conclusion, similar results were obtained compared to studies of pruning lemon trees of Spain, with the exception of sulfur and fixed carbon content and a higher melting point of ash. The results classify this biomass as suitable to be used as fuel.
