“…And this difference can be again attributed to different growing conditions of oil palm (Chiew and Shimada, 2013). High values (over 30%) of volatiles produce more heat during the combustion process, which causes pellets to burn more quickly and thus be less convenient as fuels (Jain, 1994;Kataki and Konwer, 2002). With regard to MC, Lam et al (2015) reported 13.5% in EFB pellets, higher value than the one obtained in this study.…”

“…These results were in parallel with the findings of Nasser et al [6] on vine prunings (FVI ranging from 225 to 508). On the other hand, a wide range of FVI values, from 369 for Litsea polyantha to 2089 for A. nilotica, which presented ash contents ranging from 3.6% to 0.9%, respectively, has been found [29]. This means that the ash content is the most important variable adversely affecting FVI values [6].…”

Abstract:The objective of the study was to analyze chemical structure of date palm (Phoenix dactylifera L.) by employing ultimate, proximate and thermo-gravimetric techniques. Samples from different anatomical parts of date palm, namely trunk, frond base, frond midrib, leaflets, coir, fruit stem, date stone, and fruit empty bunches were considered for the experiments. Based on the findings in this work palm leaflet samples gave the highest amount of extractives content (32.9%), followed by date palm stone specimens with 31.5%. Cellulose content values of 32.8% and 47.5% were obtained for date palm stone and palm coir samples, respectively. Overall the hemicellulose contents of all samples were relatively similar to those of typical wood or non-wood lignocellulosic materials with the two exceptions of palm coir and palm leaflets. Both palm coir and palm leaflet specimens had 12.6% and 16.1% hemicellulose content. Volatile matter values of 74.3% and 87.5% were determined for leaflets and fruit empty bunch samples. The ash content of the samples ranged from 1.4% for date stone to 15.2% for palm leaflet samples. The thermal decomposition was completed below a temperature of 500˝C with an exception of those samples taken from palm leaflets. Taken together the data indicate that date palm stone and palm coir revealed could be more viable for renewable energy production than the other specimens considered in this work.

“…The determination of N is another useful element to determine the energetic attitude of a biomass, although it is not yet possible to provide the optimal range of its content in the tree species to be used for energy purposes [18]. The percentage content of C, N and H may also be useful for the indirect estimation of heating value, even though the biological and structural variability of the considered species, the different harvesting period, the growth environments examined, etc.…”

Abstract:We set out to determine the particle-size distribution, the fiber, the bark and the leaves content, the heating value, the CNH and the ash content of a wide sample of wood chips, collected from 10 forestry and 10 agroforestry production sources. This sampling focused on two main production types: forestry (Full Tree System-FTS-and logging residues-LR) and agroforestry (Short Rotation Coppice-SRC). For the forestry production wood chips from coniferous and broadleaf species were considered. For the agroforestry production wood chips from poplar plantations were examined (different clones with two different harvesting intervals). Overall, we collected 400 samples. Particle size distribution was determined with an automatic screening device on 200 samples. The higher heating value was determined on 200 subsamples using an adiabatic bomb calorimeter. The CNH and the ash content was ascertained on another 200 subsamples. FTS and SRC (with three year old sprouts) offered the best quality, with high fiber content (71%-80%), favorable particle-size distribution and good energetic parameters. On the contrary, both logging residues and SRC (with two year old sprouts) presented a high bark content (18%-27%) and occasionally a mediocre particle-size distribution, being often too rich in fines (6%-12%), but the energetic parameters are in the normal range.
