Energy potential of co-products generated from Jatropha biodiesel production
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 3
Abstract
This study aimed to evaluate the energetic use potential of co-products from chain of Jatropha biodiesel production. For this, the higher heating value and immediate analysis (volatile matter, ash and fixed carbon content) were determined for epicarp samples (shell), cake from the press extraction process, and the bran from the solvent extraction process. Co-products of the biodiesel production chain from Jatropha under shells, cake, and bran form have energetic characteristics that make possible its use for energy production for used in different processes. The oil content has an effect on the calorific value of jatropha co-products. The higher the residual oil content in the pie or bran, the greater the energy potential. The peas, the pie and the bran presented calorific power similar to eucalyptus wood and sugarcane bagasse. The last one is widely used in cogeneration systems in the sugar-alcohol industry and can be used directly or compacted in the generation of heat for processes both in the processing industry and in the field. The pie (obtained by mechanical pressing) was the co-product that presented better conditions for direct burning when compared to the other evaluated materials.
