VERFAHREN ZUR VERSORGUNG EINES ROHRES MIT KOKSANLAGERUNG- UND KOHLENMONOXIDHEMMENDEN EIGENSCHAFTEN BEI DEM THERMISCHE KRACKEN VON KOHLENWASSERSTOFFEN

摘要

The rate of formation of carbon on the surfaces of thermal cracking tubes and the production of carbon monoxide during thermal cracking of hydrocarbons are inhibited by the use of cracking tubes treated with an antifoulant, including tin compound, silicon compound and sulfur compounds in the presence of a reducing gas such as hydrogen. Additionally, the concentration of carbon monoxide in a pyrolytic cracking process product stream is reduced by the treatment of the thermal cracking tubes of such process with a reducing gas having a concentration of a sulfur compound.
