METHOD FOR PROLONGING THE EFFECTIVENESS OF A PYROLYTIC CRACKING TUBE TREATED FOR THE INHIBITION OF COKE FORMATION DURING CRACKING

摘要

Process for prolonging the effectiveness of a pyrolytic crackingtube which has been treated with an antifoulant for inhibiting the formation ofcoke during the cracking of hydrocarbons. The benefits of such treatment areenhanced by the desulfurization of a sulfur-containing feedstock prior tocharging it to the treated pyrolytic cracking tube.
