“…The results of the sensitivity analysis of the fast pyrolysis of banana pseudo-stem conducted by Abdullah et al [23] were used to validate this study. Of the studies reporting the pyrolysis of banana wastes [22][23][24][25][26], theirs alone gave a report of temperature sensitivity. Some discrepancies with fast pyrolysis results will be present due to differences in the systems.…”

Pyrolysis has been established as a good technique of recovering energy from biomass. In this study, a thermodynamic model was developed on ASPEN Plus V8.8 to study the temperature sensitivity and yield of products from the pyrolysis of different banana wastes. The wastes considered were banana peels, pseudo-stem and leaves. The model was validated with experimental results for pseudo-stem pyrolysis. From comparison, the pseudo-stem was observed to give a slightly higher yield of gas compared to the other residues. Thermodynamic predictions of gas yield are similar for the different feedstock at low temperatures but varying at higher temperatures with the leaves producing less. Furthermore, the yield of oil from leaves is less and that of char is higher than for the other residues. The fluid phase products (bio-oil and syn-gas) were higher for pseudo-stem than for the other residues due to greater proportion of volatile matter from the proximate analysis. The suitability of banana pseudo-stem for bio-oil production via pyrolysis is established in comparison with the other residues studied. The leaves and peel are more suitable for low-temperature thermochemical processing for bio-char production.

“…A very comprehensive discussion of the application of RSM for optimising chemical and biochemical processes has been undertaken by Baş and Boyacı [32]. RSM models have found applications in biodiesel production [12,33], pyrolysis [34], steam reforming [35][36][37], adsorption [38] and a host of other thermochemical and biochemical processes. Standing on this premise, RSM will be applied in optimising the production of biodiesel from Euphorbia lathyris using methanol and NaOH catalyst.…”

Caper Spurge (Euphorbia lathyris) is a weed that is non-edible and have no other competitive use. The oil has a high percentage of mono-unsaturation in fatty acid composition hence an excellent non-edible feedstock for biodiesel production. The aim of this work is to model the production of biodiesel from E. lathyris using methanol and NaOH catalyst on an in silico platform. Based on the results obtained from the model, the effect of the process factors such as temperature, methanol-oil ratio and catalyst loading on the reaction conversion was evaluated. A quadratic model was developed using response surface methodology for estimating the response based on the levels of the process factors. Analysis of variance revealed that the model was significant. The optimal conversion was predicted as 83.5% and can be achieved at a temperature of 65 °C, 9.99 mol/mol methanol-oil ratio and 4.29 wt% catalyst loading. The study has successfully established a simulation framework to study the production of biodiesel from Caper spurge oil (E. lathyris L.).

Thermochemical conversion of biomass is a technique used in recovering its energetic content and for the production useful biofuels. A lot of wastes/residues are generated from the harvesting and consumption of banana fruits. This study developed an ASPEN Plus model for the gasification of banana (Musa Spp.) residues pseudo-stem, the peels and the leaves. The model will be used to study the effect of gasification temperature, gasification pressure and air-fuel ratio (AFR) on the selectivity of the chemical species in the product stream. For all three residues, the selectivity of hydrogen increases with temperature with temperature. At the optimum temperature, the hydrogen molar selectivity in the product stream is 56% (900oC), 55% (900oC) and 53% (700oC) for pseudo-stem, peels and leaves respectively. At the optimum atmospheric pressure, the hydrogen molar percentage in the product stream was 48%, 49% and 50% for pseudo-stem, peels and leaves respectively. At the optimum AFR, the hydrogen selectivity in the product stream is 55%, 52% and 46% for pseudo-stem, peels and leaves respectively. All three residues are reasonably good feedstock for the gasification process but the pseudo-stem possesses a marginal advantage over the others.
