The proximate analysis, oil content, and higher heating value were all determined experimentally and compared to other biomass previously published in the literature. The findings appear to be similar to other biomass materials utilized as solid biofuel feed-stock materials. Olive cake and wood samples have lower calorific values than anthracite coal, ranging from 25% to 40% lower. According to the results of this study, olive cake samples had the highest oil extractive content (14.5 wt%), followed by pine and beech woody samples with 8.9 wt% and 3.1 wt%, respectively. The calorific values of the biomass samples tested ranged from 18 to 22 MJ/kg, making them suitable for use as fuel. Moreover, the high volatile matter content (78% to 93%) was appropriate for chemical energy conversion by gasification or combustion process. Jordan can create roughly 8000 tons of pomace oil per year from the waste solid olive cake, based on existing results. Furthermore, the olive cake’s energy potential in Jordan is estimated to be 38 MW based on the higher heating value of the tested samples and the annual quantity of this resource. In the meantime, due to limited annual production, Jordanian firewood has the modest energy potential (2.4 MW).展开更多

The use of biomass fuels derived from agricultural waste biomass, generally available in large quantities, has been advocated. This article, therefore, presents some bio-fuels in use or in acceptability test phase in some countries of West Africa and particularly in Senegal but also their characteristics, compared to those of wood or wood charcoal. Samples were prepared and analyzed for moisture content, ash content, volatiles mater, fixed carbon and calorific value. The results indicate that charcoal and bio-charcoal (not mixed with clay) have the best calorific value, while pellets and typha briquettes have the best results in volatile matter and fixed carbon. The results of moisture are generally satisfactory against the use of clay as a binder detrimental to fuel performance. These results suggest that pellets and bio-fuels are used as an energy source for domestic purposes;that the binder is changed in others;pelletizing and briquetting transformations are expanded in other residues such as rice husks, peanut shells.展开更多
