We were previously shown that those altered by Extremis aren't immortal. Tony killed one on the airplane by blasting out his heart. I think the assumption in that situation is that without a heart to feed blood to the rest of your body you'll die.
When Killian was blown up the first time, he took a lot of damage, but it seems that his body mostly stayed in tact.
The second explosion by Pepper, as Elfangor states, was probably too much for Killian's body to handle, and he died.
