Potential of exhausted olive pomace for gasification

摘要

The exhausted olive pomace was fully characterized for the application as combustible in gasification. Nowadays, this waste is sold as an animal feed or fertilizer, losing its potential as a combustible for energy production. To analyse the potential as a fuel, a full physic-chemical and energetic characterization were performed. With the results was possible to conclude that: the waste was not dangerous, it is a potential combustible, releases 100.65 W g~(-1) at 496°C and have a full burning at 600°C. Considering all the results, was conducted a theoretical study, varying the amount of oxygen injected, in a range of 0.21-0.39 kmol kmol~(-1) of waste, allowing the selection of the best work point in terms of net energy. From the theoretical analysis, it was possible to obtain the syngas composition for all the points of the study. The results and directives for the gasification are presented in this paper.
