Pre-pyrolysis and pyrolysis ashes of oil palm empty fruit bunch biomass from South Tangerang, Indonesia: Mineral probabilities and their potential applications based on XRF analysis

In this study, oil palm empty fruit bunch biomass from oil palm plants in Puspiptek area, South Tangerang, Indonesia was pyrolyzed with a temperature of 700 °C for about 4 hours flowing by inert gas (N2) for about 30 minutes. This process yields biochar which consists of two parts, i.e. carbon conte...

Description
Summary:In this study, oil palm empty fruit bunch biomass from oil palm plants in Puspiptek area, South Tangerang, Indonesia was pyrolyzed with a temperature of 700 °C for about 4 hours flowing by inert gas (N2) for about 30 minutes. This process yields biochar which consists of two parts, i.e. carbon content and ash content. This study aimed to determine the mineral composition of ash content. An X-ray Fluorescence (XRF) characterization was performed in order to determine the mineral composition of ash content. Two samples were used for being characterized by XRF, i.e. pre-pyrolysis ash and pyrolyzed ash. The result of XRF characterization showed some of predicted minerals such as K2SiO3, SiO2, CaSiO3, Fe2SiO5, FeAlSiO5, CaSO4 and P2SiO7 on pre-pyrolysis ash and CaCO3, Fe2SiO5, K2SiO3, CaSiO3, CaSO4, MgSiO3, P2SiO7, Al2SiO5 and MnSiO3 on pyrolyzed ash. Based on these predicted mineral compositions, pre-pyrolysis ash has a potency to be used as a mixing material for anti-weathering coating for wood and ceramics applications. On the other hand, pyrolyzed ash has a potency for being used as fertilizer and or fertilizer mixture.
