Abstract

CON UN PROCEDIMIENTO COMBINADO, PARA EL TRATAMIENTO TERMICO Y QUIMICO DE BIOMASA QUE CONTIENE LIGNOCELULOSA Y PARA LA OBTENCION DE FURFURAL SE AÑADE DISCONTINUAMENTE LA BIOMASA A UN DIGESTOR (1) CALENTADO BAJO ADICION DE LIQUIDO DE HERVIR EN EL DIGESTOR (1) Y SE EXTRAE DISCONTINUAMENTE CELULOSA O BIOMASA PRETRATADO EL DIGESTOR (1). PARA GARANTIZAR UN RENDIMIENTO ALTO DE FURFURAL SE EXTRAE DURANTE DE LA FASE DEL CALENTAMIENTO, LIQUIDO DE HERVIR DEL DIGESTOR (1) Y SE AÑADE UNA INSTALACION PRODUCTORA DE FURFURAL, Y SE RETORNA EL LIQUIDO DE HERVIR QUE ESTA LIBERADO AL MENOS POR LA PARTE MAS GRANDE PENTOSAS O BIEN FURFURAL AL DIGESTOR.
