Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO PARA LA COMBUSTION PARCIAL DEL LICOR CONSUMIDO DE CELULOSA UTILIZANDO UN QUEMADOR CONECTADO A UN REACTOR MIENTRAS SE AÑADE UN GAS QUE CONTIENE OXIGENO, MANTENIENDO UNA TEMPERATURA DE MAS DE 700 C EN EL REACTOR Y AÑADIENDO AL MENOS LA MITAD DE LA CANTIDAD NO COMBUSTIBLE REFERIDA DE OXIGENO AL REACTOR PARA LA COMBUSTION PARCIAL DEL LICOR CONSUMIDO DE CELULOSA A TRAVES DEL QUEMADOR, EN FORMA DE OXIGENO CALIENTE QUE CONTIENE GAS AÑADIDO A TRAVES UN CANAL DISPUESTO COAXIALMENTE ALREDEDOR DE UNA LANZA DE LICOR PREVISTA PARA LA ADICION DE DICHO LICOR CONSUMIDO DE CELULOSA, CON LO QUE LA RELACION DE PESO ENTRE EL OXIGENO DEL GAS QUE CONTIENE OXIGENO Y LOS SOLIDOS DE LICOR CONSUMIDO DE CELULOSA ES DEL ORDEN DE 0.1-0.7:1.THE PRESENT INVENTION REFERS TO A PROCESS FOR THE PARTIAL COMBUSTION OF THE CONSUMED LIQUOR OF CELLULOSE USING A BURNER CONNECTED TO A REACTOR WHILE ADDING A GAS CONTAINING OXYGEN, MAINTAINING A TEMPERATURE OF MORE THAN 700 C IN THE REACTOR AND ADDING THE REACTOR AND ADDING THE OF THE NON-COMBUSTIBLE QUANTITY REFERRED FROM OXYGEN TO THE REACTOR FOR THE PARTIAL COMBUSTION OF THE CONSUMED LIQUOR OF CELLULOSE THROUGH THE BURNER, IN THE FORM OF HOT OXYGEN CONTAINING GAS ADDED THROUGH A COAXALLY READY CHANNEL AROUND THE WIDTH SAID CELLULOSE CONSUMED LIQUOR, SO THE WEIGHT RATIO BETWEEN THE OXYGEN OF THE OXYGEN-CONTAINING GAS AND THE SOLIDS OF CELLULOSE CONSUMED LIQUOR IS OF THE ORDER OF 0.1-0.7: 1.
