O Resumo deverá ser escrito em língua inglesa e conter no máximo 300 palavras em itálico. Deve Investigações anteriores sugerem que a aplicação de catalisadores de argila funcionalizada apresenta eficiência catalítica semelhante aos métodos convencionais de produção de biodiesel. Entretanto, pouca atenção tem sido dada aos estudos sobre a aplicação de outros compostos contendo K e Na na produção de catalisadores argilosos. Assim, o presente trabalho investigou a produção e aplicação na transesterificação de etil e metila de bentonita funcionalizada por K 2 CO 3 , KCl, K 2 SO 4 , NaF, Na 2 SiF 6 e KHSO 4 . As reações de transesterificação do óleo de algodão foram realizadas a 70°C por 2 h sob agitação e refluxo utilizando metanol ou etanol. Bentonita e catalisadores foram caracterizados por indicadores de Hammett e difração de raios X. Os resultados sugerem que os compostos químicos de K e Na interagem fortemente com a argila. Os catalisadores ácidos proporcionam uma baixa conversão do óleo de semente de algodão e os catalisadores alcalinos apresentam alta atividade catalítica na transesterificação de metila e alguma conversão na reação com etanol em temperaturas moderadas.Downloads
