An eco-friendly catalyst prepared from rice husk was used to synthesize dihydropyrimidinones (DHPMs) and achieved a yield of 92%.
In this work, a commercial cellulolytic cocktail was immobilized on glutaraldehyde activated chitosan gel. The concentration in the gel preparation, pH, immobilization time and enzymatic loading were evaluated. Immobilized cellulases showed better hydrolysis performance when an enzyme of 134 mg protein/g carrier used for at pH 9.0 30 minutes. Hydrolysates with glucose content 13.43 10.35 g/L obtained Avicel pretreated sugarcane bagasse as substrate, respectively. cellulase lost 60% its after...
Teaching and research laboratories generate wastes of various compositions volumes, ranging from diluted aqueous solutions to concentrated ones, which, due milder self-regulation waste-management policies, are carelessly discarded, with little attention given the consequences for environment human health. In this sense, current study proposes application supercritical water oxidation (SCWO) process treatment complex refractory wastewater generated in teaching universities. The SCWO, which...
O uso do bagaço como biomassa para a produção de bioetanol apresenta uma série vantagens: já vem processado das indústrias, está disponível em grandes quantidades, tem custo mínimo, pronto no local, evitando aumento devido ao transporte. Neste sentido, este trabalho teve por objetivo análise desempenho abacaxi, oriundo indústrias suco, submetido pré-tratamento com hidróxido cálcio e peróxido hidrogênio alcalino, partir um planejamento fatorial 2
Com a crescente e competitiva demanda do etanol em relação aos combustíveis fósseis surgiu um novo desafio no cenário mundial: aumentar produção sem área plantada, evitando assim competitividade por espaço com outras culturas alimentícias, caso qual se enquadra proposta de segunda geração. Neste sentido, este trabalho teve objetivo análise desempenho bagaço abacaxi como possível biomassa para 2ª Foi avaliada etapa hidrólise enzimática, visando maior obtenção ART (Açúcares Redutores Totais)....
The supercritical water gasification (ScWG) technology is a promising alternative to produce hydrogen rich syngas from renewable sources such as ethanol or residual glycerol the biodiesel manufacture. ScWG process can achieve high selectivity towards and elevated conversion efficiencies in short reaction times. In this work, of mixtures were investigated absence catalysts. At constant pressure 25 MPa, effects temperature (500 – 700 °C), feed flow rate (10 20 mL min-1), organic carbon...
Palladium and nickel supported on Nb2O5 were synthesized via wet impregnation method tested for the Suzuki-Miyaura reaction. The catalysts characterized by X-ray fluorescence, textural analysis, scanning transmission electron microscopy, thermogravimetry/differential thermal analysis diffraction. catalyst resulted in high isolated yields (91%). Satisfactory (48%) achieved employing catalyst. Hot filtration experiments performed to evaluate reaction heterogeneity. submitted consecutive...
