“…7. While our study results obtained for single-axis compression could not be directly compared with results published in literature [21], because the measurement parameters used were different, the characteristic curves and the measured results were close to those obtained by other researchers, validating our tests. Since the curve points were plotted using the same x coordinates for all curves, averaging was performed based on the forces that caused the different deformation values.…”

“…Mechanical behavior under single-axis load was investigated using a piston-operated compaction cylinder with an external/internal diameter of 100 / 80 mm [21]. The piston and its IN-STRON 2525-802 load cell was mounted on the vertically moving slider of an INSTRON 5581 universal mechanical measurement instrument (UMM), with the compaction cylinder mounted on the mounting plate in accordance with the horizontal position of the piston (Fig.…”

“…Prior to the transesterification, oils were usually extracted from oil seeds through various methods such as mechanical [6][7][8], pressurized solvent extraction [9], soxhlet extraction [10], ultrasonic extraction [11,12], aqueous enzymatic oil extraction (AEOE) [13,14], stirring and shaking extraction [15] to mention a few. These methods have been reported to be used for the extraction of vegetable oils and other plant essential components, each with intrinsic advantages and shortcomings [16].…”

Background The energy requirements are globally on a rapid escalation, as technology advances, which is also true for a developing country like Nigeria, which is dependent on fossil fuels and its derivatives. Apart from its adverse effect on its economy, it has also negative impacts on the health and the environment, in general. However, investments in renewable energy are faced by the competitive oil prices, the very high investment cost for renewable energy, and high local electricity prices. This paper appraises the attractiveness of investing in renewable energy sources over the continued use of non-edible oil for electricity generation. Methods This paper explores the application of biomass seed oil to produce a renewable fuel (biodiesel) using heterogeneous base catalyst. Meanwhile, two-step processes were employed to produce the biofuel. In the first step (esterification), the acid value of the oil was reduced to the recommended limit (FFA ≤ 1.5) using H2SO4, while in the second step (transesterification), the catalyst calcination of grounded Brette Pearl Spar Mable (BPSM) pre-soaked in methanol was used as a biobase for biodiesel production. For the optimization, minitab response surface (MRS) and artificial neural network (ANN) were employed to model and optimize the process variables responsible for the optimum production of the oil and the biodiesel. Results The result presented showed that T. peruviana seed was found to be rich in oil with an average yield of 44.00% (w/w), and the oil was highly unsaturated with a high FFA. The maximum experimental biodiesel yield obtained was 86.00% at a catalyst amount of 4 g, a reaction time of 70 min, and a methanol/oil ratio of 0.1(v/v). This result was validated in triplicate under the same conditions, which yielded 85.70% (v/v) for MRS and 85.98% (v/v) for ANN. Furthermore, the optimization results also indicated that the p values (p < 0.05) of the model terms were significant, and the accuracy of the models achieved by MRS and ANN based on R2 depict that both optimization tools gave good predictions of R2 (MRS: R2 = 99.98% and ANN: R2 = 99.97%). The properties of the biodiesel, as described in other earlier reports using the same feedstock with different catalysts, indicated that the produced biodiesel had properties which agreed to those reported in the literature. Conclusions T. peruviana seed has proved to be a good biomass raw material for oil production, and its conversion to biofuel using a heterogeneous biobase catalyst showed its suitability as a renewable environmental friendly fuel. Government should invest in more sustainable sources of energy by imposing law for the use of non-edible oil or decreasing the price of electricity.

The mechanical behavior of Enset pulp commonly known as "kocho" in Ethiopia was examined under compression loading test involving a compressive device and a pressing vessel. The pulp was pressed at initial pressing height 70 mm at deformation values ranging between 5 mm and 30 mm and pressing speed 10 mm/min. Applying the tangent curve equation, the mathematical description of the dependency between compressive force and appropriate deformation of Enset pulp was described. The maximal yield of liquid contained in the pulp and the liquid emerged during the pressing process were determined. The dependency between liquid emerged and deformation was mathematically described, which showed a linear function. It was further observed that the liquid contained in the pulp surfaced throughout the pressing process. Deformation energy, volume energy and gradient volume energy in relation to deformation were respectively calculated. It was seen that deformation of Enset pulp at 20 mm was energy efficient compared with deformations lower or greater than 20 mm. PRACTICAL APPLICATIONThe theoretical linear model determined in this present study for the description of mechanical behavior of Enset pulp under compression loading provides useful information for application in nonlinear pressing involving screw presses for the design and development of simple technology for optimization of energy requirement in Enset pulp processing and other important products. This new technology when developed would contribute substantially to the improvement of Ethiopian's and other African countries' food security.
