Abstract

EL PRESENTE INVENTO SE REFIERE A UN METODO PARA PRODUCIR PASTA PREPARADA BAJO CONDICIONES ALCALINAS. EN DICHO METODO EL MATERIAL DE CELULOSA ES PUESTO EN CONTACTO, EN UN DIGESTOR, CON UN LICOR DE SUSPENSION ALCALINA QUE CONTIENE DISUELTOS COMPUESTOS DE SODIO Y POTASIO, CON UN LICOR DE SUSPENSION AGOTADO SEPARADO DEL MATERIAL QUE CONTIENE CELULOSA Y EXTRAIDO PARA LA RECUPERACION DE ENERGIA EN PRODUCTO QUIMICOS, DONDE: A) EL INDICE MOLAR, CALCULADO COMO K/K+NA, ENTRE POTASIO Y SODIO EN UN LICOR EN SUSPENSION AGOTADO, EXCEDE 0,25 ; B) EL LICOR DE SUSPENSION AGOTADO SE CONCENTRA CON RESPECTO A SU CONTENIDO DE MATERIAL SOLIDO, Y ES SOMETIDO A UNA OXIDACION PARCIAL EN UN REACTOR, RESULTANDO EN LA FORMACION DE UN GAS COMBUSTIBLE QUE ES EXTRAIDO DEL REACTOR; C) SE SUMINISTRA UN GAS QUE CONTIENE OXIGENO AL REACTOR PARA APOYAR LA OXIDACION PARCIAL; D) LA TEMPERATURA DE OPERACION EN EL REACTOR SE AJUSTA A ENTRE 400-1200 GRADOS C; E) EL GAS COMBUSTIBLE OBTENIDO EN ASOCIACION CON LA OXIDACION PARCIAL YQUE CONTIENE COMPUESTOS DE METAL ALCALI LIQUIDO/SOLIDO, SE SEPARA LA PARTE PRINCIPAL DE SU CONTENIDO DE ALCALI Y SE UTILIZA PARA LA PRODUCCION DE ENERGIA UTIL; F) LOS COMPUESTOS DE METAL ALCALI QUE HAN SIDO SEPARADOS DEL GAS PROCESADO, SON DISUELTOS EN LIQUIDO, EL CUAL ES UTILIZADO BIEN POR COMPLETO O EN PARTE PARA PREPARAR UN LICOR DE SUSPENSION.
