The answer is yes, although I rarely hear of a runaway in an NHT. Olefinic feeds are quite reactive and can exacerbate the problem. Note that you can start up using olefinic feeds with Eurecat's Totsucat CFP Sulfiding and Activation service. The CFP treatment (Cracked Feed Protection) has also been shown to decrease the deactivation rate caused by running olefinic feeds.

Absolutely, yes.
