In the Amazon, Euterpe oleracea Mart. (açaí), is part of the identity of traditional communities, and the fruit is integrated into their everyday sociocultural dynamics. Hydrolysis and pyrolysis of residual biomass can be alternatives to yield sugars, ethanol, biochar and bio-oil. The açaí seeds subjected to oxidative pretreatment followed by acid hydrolysis increased cellulose to fermentable sugars (reaching 23.5%) and second-generation ethanol production (17.441 L t−1). Açaí oil (ca. 30%) was extracted using a Soxhlet apparatus (using hexane as solvent) and detected through gas chromatography coupled to mass spectrometry (GC-MS), where acids accounted for 82.43% of the total composition, while alcohols comprised only 13.15%. For pyrolysis, temperatures (500 and 550 °C), time (20 and 30 min), and activation temperature (750 and 800 °C) were evaluated, resulting in yields of ca. 22% for biochar and 30% for bio-oil. For the bio-oil, the main compounds detected by GC-MS were acids (16.3%), aldehydes (13.08%), amides (12.19%), alcohols (6.72%), and phenols (4.64%). The obtained biochar displayed surface area values of 553.7 m2 g−1 and 10% crystallinity, indicating its more amorphous nature.

The Legal Amazon Region has numerous lignocellulosic biomasses with unknown technological properties, contrasting with an urgent demand for energy transition towards a more sustainable economy. This study analyzed the biomasses of baru husk (BH), cupuaçu husk (CH), and pequi seed (PS) through slow pyrolysis at 650 °C to assess the suitability of the bio-oils and biochars as potential biorefinery bioproducts. The physicochemical characterizations showed that all residues are potential candidates for bioproduct production, with CH biomass obtaining the best results for biochar production due to its high carbon content (80.65%) and surface area of 298.0491 m2 g-1, while BH and PS are more suitable for bio-oil production due to their high volatile matter content (> 84%). The main compounds in the bio-oil identified by gas chromatography-mass spectrometry (GC-MS) were phenolic (48.5, 56.7, and 60.36% for BH, CH, and PS, respectively) and furanic (22, 12.17, and 10.28% for BH, CH, and PS, respectively). Finally, it is concluded that based on the physicochemical and morphological characteristics obtained in this study, the pyrolysis products have potential for future investigation in various processes such as adsorption, carbon sequestration, and obtaining valuable chemical compounds, contributing to the promotion of the bioeconomy through sustainable waste management. properties economy , (BH) (CH) (PS 65 C biooils bio oils bioproducts 80.65% 8065 80 (80.65% 2980491 298 0491 298.049 m g1, g1 g 1, 1 g-1 biooil oil > ( 84%. 84 84% . 84%) chromatographymass chromatography mass GCMS GC MS (GC-MS 48.5, 485 48 5 (48.5 567 56 7 56.7 6036 60 36 60.36 respectively 22, 22 (22 1217 12 17 12.17 1028 10 28 10.28 respectively.

Abstract: The objective of this work was to obtain, through the tree pruning pyrolysis, coal to be used in the removal of pollutants present in gray waters. The coal obtained during the process was used in a gray water filtration column and dye adsorption test. In this investigation it was proposed the treatment of gray water by the following series steps: (a) coagulation/ flocculation, (b) decantation, (c) sand filtration and (d) coal filtration column. The maximum coal yield was 60.10% obtained at 360 ºC and heating rate of 30 ºC/min. The gray water polishing using the coal obtained from the tree pruning pyrolysis process was efficient in the removal of the studied analytical parameters. For turbidity, COD, total solids and residual chlorine parameters, the removal values were 99, 98, 71 and 100 %, respectively. The charcoal from the filtration column was responsible for removing organ matter of gray water.

Uma das chaves para manter a melhoria da alta qualidade de fabricação está no uso de cartas de controle. Neste trabalho, cartas de controle multivariada baseadas nos escores da componente principal mais significativa e no sinal analítico líquido foram desenvolvidas para monitoramento simultâneo da qualidade de dois princípios ativos (isoniazida e rifampicina) numa formulação farmacêutica (amostras produzidas no laboratório e na produção) empregando um espectrômetro portátil na região do infravermelho próximo. Os limites previstos em ambas as cartas multivariadas foram calculados a partir das especificações de qualidade da formulação farmacêutica (± 5% do valor nominal para cada princípio ativo). O uso das cartas de controle multivariadas forneceu uma simples e poderosa ferramenta para avaliar a formulação farmacêutica aliada a espectroscopia no infravermelho próximo. O procedimento é rápido e flexível para o monitoramento da produção desta formulação farmacêutica produzida na UFRN/Brasil, com o objetivo de introduzir a tecnologia analítica de processos ao tratamento de tuberculose pulmonar.

One of the keys to maintain high manufacturing quality improvement is the use of control charts. In this work, multivariate control charts based on significant principal component (PC) scores and net analytical signal (NAS) were developed to simultaneously monitor the quality of two active pharmaceutical ingredients (API) (isoniazid and rifampicin) in pharmaceutical formulation (laboratory samples and production samples) using a portable near infrared spectrometer. The limits for both multivariate charts were estimated using the quality specifications from the pharmaceutical formulation (± 5% of the nominal content of each API). The use of these multivariate control charts has provided a simple and powerful tool to evaluate the content of pharmaceutical formulations based on isoniazid and rifampicin capsules combined with near infrared spectroscopy. The procedure is rapid and adjustable for monitoring the production of the pharmaceutical preparations produced at UFRN/Brazil toward the process analytical technology (PAT) for the treatment of pulmonary tuberculosis.
