A Preliminary Study of Scanning Electron Microscopy (SEM) for Characterization of the Wood Pellet Process of Sengon Wood (Albizia Chinensis)

Abstract

. Previously, Sengon wood waste from existing sawmills was underutilized. Therefore, one way to utilize this wood waste is to convert it into fuel because the energy demand in this world continues to increase. In doing so, an initial study was conducted to determine the characteristics of wood pellets from Sengon wood using Scanning Electron Microscopy-Energy Dispersive of X-ray Spectroscopy (SEM-EDX), resulting in more porosity in the middle than at the bottom and top because the middle is denser than the inside of the Sengon wood pellet, while the upper part has fewer pores because the outer part of the wood pellet experiences friction with the ring die so that the resulting pores are smoother. Meanwhile, on average, the elements that have been tested have the highest atomic weights, namely C-K elements (40.36%); elements O-K (52.08%); element CuL (1.29%); Elements of AIK (0.85%); SiK element (1.95%); CIK elements (0.42%); KK elements (1.39%) and CaK elements (1.64%). sawdust. Biomass resources have been considered as one of the most promising renewable raw materials to replace fossil resources today. potential application of renewable energy sources to replace fossil fuel combustion as the main energy source in various countries, and discusses issues related to biomass combustion in boiler power systems. where biomass includes organic produced as a result of photosynthesis as well as municipal, industrial and animal waste materials. A summary of the basic concepts involved in burning biomass fuels is presented.
