Effect of torrefaction on oil palm empty fruit bunch pelletization

Abstract

This paper focuses on the properties of raw and torrified pellet from EFB by varying different parameters including energy consumption, moisture adsorption, Meyer hardness test and pellet density. To save storage space and transport costs, it can be compressed into fuel pellets of high physical and energetic density. The pelletizing properties were determined using single pellet press and pellet stability was determined by compression testing. J Fundam Appl Sci. 2017, 9(3S), 955-968 956 Pelletization of raw and torrified empty fruit bunch (EFB) from compression single pellet press (SPP) was investigated to quantify the energy consumption and pellet properties including moisture adsorption, pellet density and Meyer hardness. Energy consumption for torrified EFB pellet were significantly higher than those for raw EFB pellet, while the moisture adsorption rate of torrified EFB pellets increased with increasing the severity of torrefaction.

Influence of Torrefaction Parameters on Elemental Properties of Torrefied Oil Palm Empty Fruit Bunch Biochar

“…Torrefaction occurs at a temperature of 200 to 300°C, duration below 2 hours with heating rate between 5-15°C/min and in an inert condition, also known as oxygen shortage [12], [13], [14]. The process is influenced by various parameters, including holding temperature, residence time, heating rate, air pressure, particle size, and moisture content.…”

Elucidating on Time and Temperature Effects on Torrified Moldy Bread

“…These data are essential for understanding the effects of moisture, volatile matter, and fixed carbon on the sample's structure and combustion behaviour. Consequently, elevated moisture levels lead to slower combustion, while high ratios of volatile matter to fixed carbon signify greater fuel reactivity [11].…”
