Abstract

SE DESCRIBE EL PROCESO PREFERIDO PARA OBTENER LA MEJORA DE BREA PRODUCIDA CON LA DESTILACION DE MATERIAL DE ALQUITRAN DE CARBON CRUDO. EL PROCESO INCLUYE EL TRATAMIENTO DE ALQUITRAN DE CARBON CRUDO POR REACCION CON FORMALDEIDO, SEGUIDO DE DESTILACION DEL ALQUITRAN DE CARBON PARA PRODUCIR BREA DE ALQUITRAN DE CARBON CUYA PRODUCCION SE INCREMENTA SIGNIFICATIVAMENTE SOBRE LA OBTENIDA SIN EL TRATAMIENTO DE FORMALDEIDO.
