Abstract

Procedimiento para la obtención de breas a partir de alquitrán de hulla.Se propone un nuevo proceso para obtener breas con diversas especificaciones a partir del alquitrán de hulla, que presenta como principal avance un aumento considerable del rendimiento en brea. Para ello se somete el alquitrán a un tratamiento con aire a temperaturas entre 250 y 350º C y con 0,2 a 2 MPa de presión. Con ello se consiguen breas de diferentes propiedades según los parámetros de operación utilizados, ysiempre con un rendimiento superior al 80 por ciento respecto al alquitrán de partida.Procedure for obtaining breasts from coal tar. A new process is proposed to obtain breasts with different specifications from coal tar, which has as its main advance a considerable increase in pitch performance. For this, the tar is subjected to an air treatment at temperatures between 250 and 350 ° C and with 0.2 to 2 MPa pressure. With this, breasts of different properties are achieved according to the operating parameters used, and always with a yield greater than 80 percent with respect to the starting tar.
