An increase in the content of reducing sugars after the pretreatment is achieved. Its effectiveness is confirmed, offering a practical procedure to produce alternative energy. Factors such as the calcium hydroxide concentration (0.1 and 0.5g Ca(OH)2/g-dry matter), liquid to solid ratio (12 and 28ml/g-dry matter), temperature (40 and 70°C), stirring rate (0 and 200rpm), an average particle size (0.45 and 1.015mm) were assessed using an experimental design. On average, kikuyo grass had the highest lignin removal (28.31%) while the African oil palm fiber had the lowest value (14.10%). The average particle size was a statistically significant factor for the pretreatment of African oil palm fiber, the stirring rate was an important factor during the pretreatment of kikuyo grass. The Ca(OH)2 concentration had a major effect on the pretreatment of sugarcane bagasse and coffee pulp waste. 2021 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49671325021 https://www.redalyc.org/journal/496/49671325021/ https://www.redalyc.org/journal/496/49671325021/html/ https://www.redalyc.org/journal/496/49671325021/49671325021.epub https://www.redalyc.org/journal/496/49671325021/movil 10.7440/res64.2018.03 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.218 Vol.88 |
