Zusammenfassung:	Process for prolonging the effectiveness of a pyrolytic cracking tube which has been treated with an antifoulant for inhibiting the formation of coke by the desulfurization of a sulfur-containing feedstock prior to charging it to the treated pyrolytic cracking tube. La presente invencion se refiere a un proceso para el termofraccionamiento de hidrocarburos, que comprende hacer pasar una alimentacion de hidrocarburos desulfurada a través de un tubo de fraccionamiento tratado, operado bajo condiciones de fraccionamiento, en donde el tubo de fraccionamiento tiene depositado sobre una superficie del mismo, en contacto con la alimentacion, al estaño y al silicio, para que resista la formacion del coque.
