WASTE OF THE LICURI (Syagrus coronata) NUT SHELLS: AN ALTERNATIVE ENERGY SOURCE

Abstract

The licuri nut shell is a potential source of biomass for energy production. The aim of this study was the physicochemical characterization of the licuri shell, focusing on the increase of its use as a fuel. The material was collected in Caldeirão Grande-BA and the characterization included a wide range of analyses such as: moisture content, bulk density, particle size distribution, ash content, volatile matter, fixed carbon, high heating value (HHV), hot water and cyclohexane/ethanol extractions, Klason lignin content, and thermogravimetric analysis (TGA). The obtained results were: moisture content (11,1%), HHV (4652 kcal.kg -1 ), Klason lignin content (36,86%), volatile content (74,91%), and fixed carbon (21,19%). The results showed that the material can be considered suitable for the purpose of generating energy 584 Revista Brasileira de Energias Renováveis, v.8, n.3, p.583-597, 2019 when compared with other types of biomasses. The ash content (3,9%) and the extractives content (46,75%) are in accordance with the values observed for the babassu nut shell, Brazilian nut shell, and coconut. Finally, by the TGA analysis, it was observed that the degradation peak occurred at 272°C with a loss of 65% of weight. With these results, the licuri nut shell has shown to be potentially promising for the energy production.

Emerging Lipids from Arecaceae Palm Fruits in Brazil

“…Licuri cake, which is rich in linoleic, oleic, and palmitic acids (35.3, 21.5, and 17.6%, respectively), improved the FA profile and the sensory attributes of lamb meat [244]. Furthermore, the licuri nutshell has been reported as a potential source of biomass for energy production based on fuel [245].…”

Biological Potential of Products Obtained from Palm Trees of the Genus Syagrus

“…In addition to the pharmacological properties already mentioned in this article, plants of the Syagrus genus still have other possible applications (Table 2) [13,14,[70][71][72][73][74][75][76][77][78][79][80], mainly due to their chemical composition. e areas that stand out the most are biotechnology, for biodiesel production at an equal quality or better than the biodiesels on the market.…”

Paralelização Do Problema De Ordenação Com O Uso De Opencl

“…O licuri, uma palmeira típica da região semi-árida, encontrada com facilidade na caatinga brasileira, possui, em média, 1357 frutos em seu cacho, que são utilizados na alimentação animal e humana (CREPALDI et al, 2001). A principal aplicação industrial do licuri consiste na produção de óleo vegetal, tanto para cosméticos quanto para alimentos, sendo a casca, que é descartada nesse processo, pode ser reaproveitada como potencial biomassa para a produção de energia (SCALET et al, 2019).…”
