“…This result corresponds to the results of Lindstrom et al 11 and Severino and Laine. 12 The trend for hydrogen production rate is identical to the methanol conversion for different preparation methods. The production rate and the volumetric percentage of hydrogen for R10:5:5 during the range of 220 to 300 °C were in the range of 0.30 to 0.68 mol/h • g catalyst, and 0.25% to 0.38%, respectively.…”

The catalytic performance of methanol reformation using Cu/ZnO/Al2O3 was investigated at low temperature. The operation conditions, such as composition of Cu, Zn, and Al, temperature, molar ratio of H2O/CH3OH, weight hourly space velocity, catalyst weight, and kind and flow rate of carrier gas (helium and air), were evaluated to obtain the optimum reaction condition. The catalysts were prepared by oxalic coprecipitation, coprecipitation, and polyol method. The weight composition of Cu, Zn, and Al prepared by oxalic coprecipitation was 15:15:5 by high-throughput screening of combinatorial chemistry method, which was the best Cu/ZnO/Al2O3 catalyst. The prepared catalysts showed high activity and selectivity towards hydrogen formation. The methanol conversion, production rate, and volumetric percentage of hydrogen using this best catalyst were larger than 95%, 0.65 mol/h x g and 59%, respectively, and the CO volumetric percentage was smaller than 0.22% when the reaction temperature was 240 degrees C. The size and dispersity of copper, and the activity and turnover frequency of the catalyst were calculated as well.

REsumoEste estudo de revisão teve como objetivo analisar a produção de acadêmica sobre o tema conteúdos de ensino da educação física escolar. Foram revisados periódicos da área 21 com extrato Qualis Capes de A2 a B4, postados até novembro de 2015, e selecionados 28 artigos que discutiam os conteúdos nos anos finais do Ensino Fundamental e Ensino Médio de modo central. Mesmo propondo novas justificativas para confirmar a presença dos esportes na escola, bem como a importância de práticas corporais inovadoras, é fundamental atentar para o modo como os conteúdos são -ou não são -problematizados e analisar criticamente porque alguns conteúdos são selecionados em detrimento de outros. Ao final, são apresentados o multiculturalismo e as bases teóricas da pedagogia crítica como possibilidade de promover aprendizagens significativas e formalizar a cultura dos estudantes na escola. Palavras AbstRACtThis review study aimed to analyze the academic production on the subject of teaching content of school physical education. They reviewed journals in the field 21 with Qualis Capes extract from A2 to B4, posted until November 2015, and selected 28 articles that discussed the content in the final years of elementary school and high school in central mode. Even proposing new justifications to confirm the presence of sports in school, and the importance of innovative body practices, it is essential to pay attention to how the contents are -or are not -problematized and critically analyze why some contents are selected over others. At the end, we present multiculturalism and the theoretical basis of critical pedagogy as a possibility to promote meaningful learning and formalize the culture of students in school.
