Resumo: Optimized conditions for palm oil and ethanol enzymatic biodiesel synthesis were determined with different immobilized lipases SiO2-PVA-immobilized lipase from Pseudomonas fluorescens and acrylic resin-immobilized lipase, Novozym®435, from Candida antartica, in solvent-free medium. A full factorial design assessed the influence of temperature (42 – 58°C) and ethanol: palm oil (6:1 – 18:1) molar ratio on the transesterification yield. Main effects were adjusted by multiple regression analysis to linear models and the maximum transesterification yield was obtained at 42°C and 18:1 ethanol: palm oil molar ratio. Mathematical models featuring total yield for each immobilized lipase were suitable to describe the experimental results.

Uma matriz de planejamento fatorial foi utilizada para avaliar a influência da temperatura (42 – 58°C) e a razão molar entre etanol e óleo de palma (6:1 – 18:1) no rendimento de transesterificação alcançado para cada preparação de lipase. Os efeitos principais foram ajustados por análise de regressão múltipla a modelos lineares e o rendimento máximo foi obtido quando o sistema operacional foi operado a 42°C com substratos contendo etanol e óleo de palma na razão molar de 18:1. Os modelos matemáticos que representam o rendimento global da reação para cada lipase imobilizada foram considerados adequados para descrever os resultados experimentais.Universidade Estadual De Maringá2011-02-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionbiocatáliseapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/759410.4025/actascitechnol.v33i2.7594Acta Scientiarum.
