FREMGANGSMAATE TIL AA MOTVIRKE DANNELSEN AV KARBON PAA METALLFLATER I EN KRAKKINGSPROSESS OG MIDDEL TIL UTFOERELSE AV FREMGANGSMAATEN.

摘要

The formation of carbon on metals exposed to hydrocarbons in a thermal cracking process is reduced by contacting such metals with an antifoulant selected from the group consisting of a combination of tin and silicon, a combination of antimony and silicon and a combination of tin, antimony and silicon.
