Abstract
Process for prolonging the effectiveness of a pyrolytic cracking tube which has been treated with an antifoulant for inhibiting the formation of coke during the cracking of hydrocarbons. The benefits of such treatment are enhanced by the desulfurization of a sulfur-containing feedstock prior to charging it to the treated pyrolytic cracking tube.
