Abstract

The coking of stainless steel 304H alloy (SS304H) has been investigated in ethane-steam mixtures in the presence/absence of a few ppm of H₂S at 700°C. In this, first detailed study of the influence of H₂S on carbon morphology on SS304H, we show that the addition of H₂S greatly altered the carbon morphology, in the long-term experiments (90 h). For shorter exposure times (4 h), carbon formation decreased as H₂S concentration was increased. This improved carbon tolerance of SS304H is likely due to adsorption of sulphfur on its surface. Addition of H₂S did not change the ethane cracking initiation temperature or the product distribution.
