“…Many of the properties discussed above influence the potential energy, such as ashes. MJ/kg for the coal castor bean meal, demonstrating that these results vary with the type of biomass and its properties (Barcellos, 2007;Vale et al, 2001;doumera et al, 2015). Thus, as a continuation of this work proposes perform pyrolysis and analyze the biomass with the greatest potential for energy generation, utilizing important information such as the characteristics described in this study.…”

The residual biomass has become increasingly important in the energy scenario due to its energetic potential and easy acquisition in isolated communities. The heterogeneous nature of biomass makes the analysis of its composition a relevant factor in the development of thermochemical processes. Several researchers show that understanding this heterogeinidade of biomass can be a strategy for optimization and search efficiency of thermochemical processes, since it is possible to predict the results and in addition, the reactor design based on the characteristics of biomass. In this context, the purpose of this work was to study the behavior of three biomass of the Brazilian savana - Dipteryx alata (baru), Hymenaea stigonocarpa (jatobá-do-cerrado) and Caryocar brasiliense (pequi), comparing the lignocellulosic results with the thermal behavior obtained by thermogravimetric analysis. The analysis were compared with results of several researchers, confirming that those analysis are parameters that influence the yield of the desired product. The results of this work elucidate that the moisture and extractives content of pequi is greater than the other biomass and that the temperature peak of cellulose and lignin from all biomass in this study are quite close. However, the hemicellulose’s temperature peak of pequi is lower than baru and jatobá’s temperature peak. Moreover, the results showed that the composition of the lignocellulosic biomass is an extremely important factor in selecting the greater reactivity material.

“…Slow pyrolysis has in the recent past received great attention in utilizing lignocellulosic biomasses into bio-oils, biochar, and non-condensable gases. It has been used to pyrolyse varied biomass feedstocks like microalgae, eucalyptus, castor meal, coconut pericarp, sugarcane bagasse, water hyacinth, cotton stalk, hazelnut shells, sunflower, Euphorbia rigida, rice straw, sorghum, switchgrass and corn stalks among others [4,[14][15][16][17]. Uganda is rich in biomasses that can be used as feedstock for pyrolysis systems.…”

Renewable energy from biomass and biodegradable wastes can significantly supplement the global energy demand if properly harnessed. Pyrolysis is the most profound modern technique that has proved effective and efficient in the energy conversion of biomass to yield various products like bio-oil, biochar, and syngas. This study focuses on optimization of slow pyrolysis of banana peels waste to yield banana peels vinegar, tar and biochar as bio-infrastructure products. Response surface methodology using central composite design was used to determine the optimum conditions for the banana wastes using a batch reactor pyrolysis system. Three factors namely heating temperature (350-550 o C), sample mass (200-800 g) and residence time (45-90 min) were varied with a total of 20 individual experiments. The optimal conditions for wood vinegar yield (48.01%) were 362.6 o C, 989.9 g and 104.2 min for peels and biochar yield (30.10%) were 585.9 o C, 989.9 g and 104.2 min. The slow pyrolysis showed significant energy conversion efficiencies of about 90% at p-value ≤ 0.05. These research findings are of primary importance to Uganda considering the abundant banana wastes amounting to 17.5 million tonnes generated annually, thus using them as pyrolysis feedstock can boost the country's energy status.
