PROCEDURE FOR OBTAINING BREAS FROM ALQUITRANES AND ITS DISTILLATES FROM THE HULLA RENTAL, THROUGH OXIDATIVE THERMAL TREATMENT.

摘要

Obtaining breasts suitable for multiple applications from distillates from high temperature coal tar with a distillation range greater than 260 ° C, by sequential and combined three-stage application under mild conditions of pressure and temperature (400 ° C, 10 bar g): oxidative heat treatment using as reagent air or oxygen, mixtures thereof, or oxygen depleted air; heat treatment in inert atmosphere, and fractional distillation. As a result, a product is obtained that presents environmental and occupational health advantages, and with potential for application for the manufacture of anodes and cathodes for the aluminum industry, electrodes, synthetic graphite, binders for the refractory industry, waterproofing and carbonaceous materials in general.
