Abstract:

This research paper presented the concept, design and construction of the device to thermogravimetric measurements and the results of tests carried out on wood pellets. The purpose of this paper is to study the characteristics and thermal degradation behavior of wood pellets for biofuel production via gasification technology and construct the device. The elemental properties of the feedstock were characterized by an elemental analyzer while thermal properties were investigated using thermogravimetric analyzer (TGA). The gasification processes were being carried out at room temperature up to 900°C in the presence of nitrogen and air as gasification agents, gas flowing at 500 ml/min. The investigated parameters are particle sizes and heating rate. The particle size used is in the range of 425 to 500 um. The heating rate applied is 10°C/min. Sample weights were varied from 0.5 to 1 gram, and a stainless – steel tray was used for the test. The further part of the paper contained the results of the tests carried out on wood pellets in the form of thermogravimetric curves. These studies are conducted by looking at opportunities to improve the energy efficiency of the gasification process of biomass.

Keywords: Characterization, Gasification, Thermogravimetric analysis (TGA), Wood pellet, Thermogravimetric measurements.
