Abstract

LA INVENCION SE REFIERE A UN PREPARADO DE LIGNINA PREPARADO A PARTIR DE UN LICOR NEGRO DERIVADO DE UN PROCESO DE DELIGNIFICACION ALQUILO, COMO POR EJEMPLO EL PROCESO DE SULFATO, PROCESO DE SODA O PROCESO DE POLISULFURO. EL PREPARADO DE LIGNINA, QUE CONTIENE LIGNINA PRINCIPALMENTE Y POR LO MENOS UNA GRAN PROPORCION DEL CONTENIDO DE SODIO DE LA LIGNINA SEPARADA DEL LICOR NEGRO, QUE SE DERIVA DE DICHO PROCESO HA SIDO SUSTITUIDO POR CALCIO, CON LO QUE SE OBTIENE UN PREPARADO DE LIGNINA QUE TIENE UNAS PROPIEDADES MEJORADAS QUE HACEN QUE EL PREPARADO SEA MEJOR PARA SER UTILIZADO COMO COMBUSTIBLE.
