 Tung’s fruits (Aleurites fordii) produce oil of great applicability in the market of painting and covering due to its drying characteristics. Tung’s oil may be an alternative for the production of new biofuels. In this study, it was evaluated the energetic potential of the fruit, oil and biodiesel obtained from the Tung. The average yielding of the extracted seed oil was 50.6%, a value similar to those presented in literature. Moreover, its density presented a value of 931.5 g L-1 and its acid index, 4.5 mg KOH g-1. In the last step of this study, biodiesel was produced by basic methyl route using potassium hydroxide. The specific mass of the produced biodiesel was 909.2 kg m-3 at 20°C; its acid index was 0.473 mg KOH g-1 and its flash point was 178°C. The values of heating values in natura and the low level of ashes in the residual biomass makes the Tung’s fruits a promising renewable clean source of energy of second generation fuel.

Pellets refer to solid biofuels for heating and power. The pellet’s integrity is of great relevant to ensure safe and effective transportation and storage, and comfort to stakeholders. Several materials that are supportive, whether organic and inorganic, to pellets exist. However, no work in the literature is linking making hybrid non-wood pellets with addition of residual biomass from distillation of cellulosic bioethanol, and this requires further investigations. Figuring out how effective this challenging agro-industrial residue could be for reinforcing non-wood pellets is accordingly the scientific point of this study focusing on management of waste and valorization of biomass. The pilot-scale manufacturing of hybrid pellets consisted of systematically pressing sugarcane bagasse with the lignocellulosic reinforcement at the mass ratios of 3:1, 1:1, and 1:3 on an automatic pelletizer machine at 200 MPa and 125 °C. Elemental contents of C and H, durability, and energy density all increased significantly from 50.05 to 53.50%, 5.95 to 7.80%, 95.90 to 99.55%, and 28.20 to 31.20 MJ kg−1, respectively, with blending the starting material with the reinforcement at 1:3. Preliminary evidence of residual biomass from distillation of second-generation bioethanol capable of highly improving molecular flammable/combustible properties, mechanical stability, and fuel power of composite non-wood pellets exist.

This article studies the possibility of intensification of Kharanorskoe deposit brown coal alkaline activation by way of electromagnetic microwave radiation (EMR) exposure in order to obtain sorbents. There is data that presents investigation of qualitative and adsorption properties of sorbents obtained from 0-2 mm brown coal samples impregnated with potassium hydroxide at a KOH / coal of 1 g / g weight ratio and subjected to thermolysis at 800 °C in the thermal shock mode. The authors carried out a detailed analysis of three options for thermal treatment of the coal-alkali mixture ahead of thermolysis: coalalkali mixture drying to indiscrete mass, EMR treatment and combination of ones. The design of a laboratory microwave oven for heat treatment of raw materials based on the use of EMR at a frequency of 2,450 MHz is presented. It was found out that the effect of electromagnetic microwave radiation with a frequency of 2.450 MHz makes it possible to increase the adsorption activity on iodine by 4-6%, reaching a value of 97%, to significantly shorten the time of preliminary heat treatment of the coalalkali mixture and to shorten the thermolysis time when sorbents obtain.

Oilseed pumpkin seeds are known to be rich in oil and nutrients. Their content in bioactive components gives them some assets that make them beneficial for human health. Although commonly consumed as a snack, pumpkin seeds are ready to claim more uses. The identification of pumpkin species is a major resource in this study. Thus, we worked with three pumpkin species: Cucurbita maxima (CMa), Cucurbita moschata (CMo) and Cucurbita pepo (CP). The species effect on the chemical composition, the content of bioactive compounds and the antioxidant activity was studied. As a result, the analysis of pumpkin seed oil revealed a polyunsaturated fatty acids (PUFAs) content ranging from 52.23% to 57.65%. Our study also revealed that this oil was a good source of phenolic compounds, in particular CMa with a value of 27.52 mg gallic acid equivalents per gram of methanolic extract and 633.51 mg/kg of total tocopherols, which gives it a very strong antioxidant character. In addition, it showed a high antioxidant potency (126.20 ± 20.44) μg/ml for CMa. In this respect, it can be said that the species effect can be a very important factor influencing the nutritional quality of pumpkin seed oil.

<p><em>The processing of passion fruit juice generates a large amount of by-products, which are seeds and shells, which are usually discarded becoming an industrial waste problem. It represents significant waste amounts, turning it a scientific and technological interesting resource to add value. The passion fruit seed oil has a wide range of application in industry, but it presents a high content of unsaturated fatty acids, being susceptible to oxidative rancidity. An alternative to avoid the exposure of the oil to atmospheric air, that leads to its oxidation, and increase its stability is its microencapsulation. In this work the passion fruits seed oil was extracted with hexane and the resulting oil was microencapsulated by emulsification solvent evaporation with poly(&epsilon;-caprolactone) (PCL). The influence of the experimental conditions, stirring rate and oil amount, was evaluated on the final average diameter (Dp) and size distribution (Polydispersion index, PDI) of the microcapsules by Students T-test with 95% of confidence. The interaction of the polymeric shell with the encapsulated oil was evaluated by Spectroscopy Fourier Transform Infrared Spectroscopy (FTIR). The yield of oil extraction obtained was equal to 29.5%. Microcapsules with 137.4 &micro;m were obtained when 500 RPM of stirring rate was used. A significant difference was observer in Dp between the blank microparticles (no oil) and microcapsules at 500 RPM. When the stirring rate was increased to 1,000 RPM any significant difference was observed in the Dp nor in PDI to microcapsules. It was possible to observe interactions between the polymeric shell and the passion fruit oil by FTIR spectra.</em></p><p><em>DOI: 10.14685/rebrapa.v5i2.151</em></p>
