The Effectiveness of Torrefied Agricultural Wastes using Conventional Heating

Abstract

The production of wastes volume from agricultural wastes have led to the selection as a renewable energy feedstock, and it has the opportunity into energy market. A comparison is made between two mode of wastes that is treated (rinse and soaking in water for 12 hours) and raw of coconut husk (CH) tap under torrefaction were investigated. This work has utilized of conventional heating method with mild oxygen concentration for the properties and combustion characteristics feedstock output. As such the influenced parameters with size of 750μm, holding temperature at (200, 240, and 280 °C), and residence duration at (20, 40 and 60 minutes) were involved within this torrefaction setup. The combustion behaviour of tested coconut husks marked three discrete zone, whereby the severity setup resulted to increase the fixed carbon (FC) value, thus leading to higher ignition temperature. The changes in mass yield and the increased of honeycomb-like and spongy-like porous structure were recorded for treated coconut husk than of the raw. The functional group results from Fourier Transform Infrared (FTIR) test showed a valuable interest of treated mode also been discussed.
