Abstract
En la presente invencion un proceso mejorado se revela para la manufactura de hidrocarburos clorados por medio de oxicloracion que producen niveles reducidos de toxinas ambientales tales como clorobencenos, bifenilos policlorados, dibenzodioxinas policloradas y dibenzofuranos policlorados. El proceso involucra la oxicloracion del lecho fijo o del lecho fluido catalizado de un reactivo de hidrocarburo que contiene de 1 a 3 átomos de carbono. El proceso de oxicloracion consiste de poner en contacto el reactivo de hidrocarburo con oxígeno o gas oxigenado y por lo menos una porcion del cloruro de hidrogeno obtenido externamente en la presencia del catalizador de oxicloracion en una zona de reaccion calentada, operada de 150 degree 8C a 600 degree C y recuperando el hidrocarburo clorado de los efluentes de la zona de reaccion. El mejoramiento consiste en el uso de por lo menos una porcion del cloruro de hidrogeno de una fuente externa diferente a la recuperacion del fluoruro de hidrogeno de la pirolisis térmica del producto del proceso de oxicloracion operado, donde el cloruro de hidrogeno externo, que contiene hidrocarburos aromáticos, es pretratado antes de utilizarse en el proceso de oxicloracion operado por medios para la remocion de los hidrocarburos aromáticos.
