“…Cellulose, the basic structural material, constitutes 40-45% of the mass of dry wood. Hemicelluloses are bound to the cellulose skeleton as a matrix substance and make up 25-35% of dry wood mass (29)(30). During wood combustion, the cellulosic materials decompose and yield various breakdown products.…”

“…At the lowest moisture content, the hub section density was lower than the other sections; when the moisture content increased and reached the highest point, the density difference exhibited from section to section of the frond became minimal. Initially, when the moisture content was higher and the vessels of the biomass tissue were filled with water, the effect of other factors on density variation, like volume ratio of vessels to fibers and fiber wall thickness, were less pronounced (Parham and Gray 1984). When the moisture is removed, the density difference will depend more on the other factors, which may vary from section to section.…”

In the gasification process, one prominent factor that affects the quality of the resulting syngas is the moisture content of the biomass feedstock. Determining the moisture content of a feedstock is considered to be one of the challenges of the process. The information about moisture content of a feedstock is required to decide the need for further drying prior to the gasification process. In this study, a novel method was developed for the evaluation of the moisture content from density of oil palm fronds (OPF) in a sufficiently accurate manner for gasification process. A total of 147 samples from different sections of freshly pruned fronds were prepared. The density of each of the samples was determined from its weight and volume. A fine sand displacement method, using fine sand and a graduated cylinder, determined the volume of OPF. The moisture content of the OPF was determined from the weight difference of the samples before and after the drying process. The experiment implied a good correlation between moisture content and density of the biomass, in which the square of the correlation coefficient (R 2 ) value was found to be satisfactory.

“…In addition to cellulose, the cell walls contain other polysaccharides known as hemicelluloses that act as a matrix for the cellulose superstructure (Parham and Gray, 1984). These compounds are branched heteropolymers that are much shorter than the cellulose molecules.…”
