Investigation of the Carbonization Behavior of Olive Pomace

Abstract

Pomace is the solid residue obtained from the olive oil production process (during pressing or centrifugation). Pomace has a chemical content high in nitrogen, potassium, and low in phosphorus and carbon. This feature of pomace makes suitable the investigation of its usability in the reduction of metal oxides after carbonization. In this study, carbonization behavior of waste pomace was investigated for the searching of waste pomace instead of coke, which is one of the most important reducers in the reduction of metal oxides, or by mixing it with coke. For this purpose, the fixed carbon and sulfur content of the samples treated after the carbonization process were examined, and the most suitable carbonization test conditions were determined. In order to determine the optimum test parameters, the pomace that supplied from Marmarabirlik was placed in a metal crucible and carbonized in a muffle furnace at temperatures of 500, 600, 700 and 800 oC and for 1, 2, 4 and 6 hours. After carbonization XRF analysis was applied to the samples . When the analysis results are examined, the highest amount of carbon was recorded as 88.4% in the sample treated at 700 oC for 6 hours, and the lowest amount of sulfur was recorded as 0.005% in the sample treated at 800 oC for 6 hours.
