Can Feed Sulfur Be Both Good And Bad?

This blog provides some historical context to my previous blog,  Metal Catalyzed Coking and feed Sulfur (S) requirements. Moreover, I will also address the flip-side of too little feed S and discuss the impact of too much and its effect on catalyst performance. I’ll also cover how catalyst Surface Area (SA) impacts the recovery from […]
